Should the Reds Consider Moving Zack Cozart Along Faster?

via daylife.com. Zack Cozart went to school in Mississippi. That means he likes food, and lots of it. Whoooweee!

Even before the Reds traded Alex Gonzalez yesterday, I had been thinking about shortstop prospect Zack Cozart for a couple of days.  I know Cozart isn't a major prospect  - he's probably not even in the top 10 in the Reds' system - but he may be the closest thing to a legitimate big league shortstop that the Reds have in the minors.  Because of this, he interests me.

For those that don't know much about Cozart, he's reputed to play gold glove level defense at shortstop.  John Sickels says this in his most recent prospect book (p. 110):

Cozart is an excellent defensive shortstop, with above average to excellent attributes in all categories.

This is a fairly typical scouting report for the 23-year old right-hander who the Reds took in the 2nd round of the 2007 draft.  The knock on him has always been his bat though.  He's said to have a quick bat, but a poor approach, swinging for power more than he really should.  He does appear to have made some adjustments this year.  He has walked twice as much this season as last in 12 fewer PA, and he's traded some home runs for doubles.  Personally, I prefer a player that has at least one serious batting skill than to be no real threat across the board.  If Cozart's patience at the plate is a reall change, his potential ability to get on base could be a good asset for him.

But that's not what interests me about him.  To me, I'm mainly interested in his glove, and maximizing his value at the big league level.  I don't think he'll ever be a great hitter, though I suppose he could be a slightly below average one, which would suffice.  The key though is to take advantage of his superior glove while it is at it's peak.  A player's overall value tends to peak around age 27 or 28, but defensive value usually peaks a bit before that.  As Beyond the Boxscore has shown in the following graph, a shortstop's range peaks around age 24, and then typically starts a general decline from there:

For a player like Cozart, whose value is going to be predominately tied to his glove, his peak is likely to be earlier than is typical.  It might make sense for the Reds to push him to the big leagues in 2010, so that they can take full advantage of his defensive value while it is peaking.  I imagine this was a similar philosophy to what the Reds did with Dave Concepcion in the 1970s.  Concepcion was a disaster at the plate his first three seasons, but they still got some value out of him because of his excellent glove. To be honest though, I'm not real sure if it was a net positive - he was TERRIBLE at the plate.

Then again, the 70s Reds also had plenty of bats at other positions, so they could sacrifice offense at shortstop.  The 2009 Reds - close to the worst offense in Reds history - don't lead us to believe that they could take on a no hit shortstop and succeed.  The ideal situation is still to acquire someone like J.J. Hardy or perhaps to move Brandon Phillips over to shortstop and get a decent bat to play 2B.  However, barring any solid acquisition, I think the Reds could do much worse than putting a cheap Cozart in at shortstop in 2010 and trying to find a strong bat in a more offensive prone position like left field.

So then,

does Cozart project out to be Janish?

Wear something sexy to my funeral.

by Pops Daniels on Aug 15, 2009 11:15 AM EDT reply actions   0 recs

he's shown a slightly better bat than Janish so far in the minors

though honestly that’s more because Janish is a terrible hitter more than Cozart being a good one. But yeah, he’s not going to be a huge upgrade over Janish.

Any idea on how Cozart's glove compares to Janish's?

Because unless it’s remarkably better, I don’t really see a serious benefit to rushing Cozart if we have the exact same player already on the roster. Sure, we’d be taking advantage of his defensive prime, but that’s where we are with Janish right now too. If we don’t rush Cozart and end up missing his defensive prime, then perhaps he just was never destined to be in the majors. Maybe instead of rushing him, we should be looking to cultivate him as trade bait?

TotalZone at Minorleauesplits.com

has Cozart rated MUCH higher than Janish, but there are big time error bars on that data. MLS has Cozart rated as +30 R/150 games over the last 2 seasons. Janish is worth about +13 R/150 over 2007/2008.

Cozart will be better than Janish

Cozart is the Reds future at SS, not Valaika. Dude at, http://redsminorleagues.com/depth-chart/ , has Cozart ahead of all other Reds minor league shortstops with his stock rising. I also heard him on Lance’s show one day saying in his opinion, Cozart has raised his stock to be in the top 3 or 5 prospects that the Reds have.

September 2010

The Reds development people believe Cozart can be in the big leagues by September next season and he’s progressing at a clip they are very comfortable. But yeah, they think he’s the future shortstop.

Do you think they are happy enough with him to not make a move on JJ Hardy, if he's available?

Lately, the Reds mgmt doesn't seem too happy with any of their prospects.....

I really do not think

the Brewers will send Hardy to a team in their division. The Red Sox will probably add him to their collection of talent.

No Bucks, No Bang

Don’t think they’re going to have the money to make a big play for Hardy or many other established players. We’ll see. Hardy is a difficult case because he’s already close to $5 mil and I believe he’s still in his arb years.

by Mr. Redlegs on Aug 15, 2009 5:53 PM EDT up reply actions   0 recs

he has at least one arb year left

possibly two if he stays in the minors long enough.

And I could see them trading Harang and splitting some of the cost with Brewers. Not that that is what I want.

And not expected until Sept. 2010, what are they going to about next year? Let Janish keep the spot warm for him?

He's past his prime for a CFer, too

The previous article in the series showed outfielders’ peak range was at age 24. Robin Yount was only 29 when he moved from SS to CF.

And he doesn’t really have the kind of bat you need for 1B or DH or LF.

I think Cashman would like to cut him loose at the end of his current contract. But the fans wouldn’t take it well. Especially since A-Rod is signed until he’s about 65.

Whats more important

An improvement at SS or the OF? I know were cluttered in the outfield with a lot of variables, but there are no sure fire RBI machine hitters in that pool.

SS

Gomes may be a husky Hairston ’08, but Jonny-Chris-Jay is a viable outfield. There is no good news about the Reds ’09 Shortstop. Janish is not The Answer much more than Sea Bass was.

To be an RBI machine, you need to have people on base to drive in

You probably won’t see one of those till 2011 at the earliest.

Interesting thoughts on Cozart, but I'm inclined to wait on him

If he was up by September 2010, that would leave plenty of defensive value for the big club and maybe he could contribute with his bat as well. If he’d only be a slight upgrade over Janish you might as well let him develop rather than risk stunting his offensive potential.

Regarding SS or LF, I think between Wlad, Gomes, and C-Dick we have a pretty good chance of fielding a league average LF than we do with our current SS pool. I’d make every effort to get Hardy or Escobar, whichever is made available. Barring that Id move BP to short and call up Frazier at 2B. He seems likely able to contribute right away.

I am content

with a Gomes LF, Dickerson CF, and Bruce RF outfield at least through the rest of the season (assuming Jay makes it back soon). I think we need to get rid of Nix and Taveras (if at all possible without eating too much salary). I think it is smart to try and trade one of Stubbs or Dickerson eventually for a SS and sign a starting pitcher in the offseason.

I think its imperative we try and go after JJ Hardy. He is fairly young, a former all star who still has huge upside, and he fits a huge need for this club. Bill Hall would be a nice get for cheap and could spell Rolen at third. A SP in the offseason is a big need as well, esp with Voltran on the DL for the better part if not all of next season. One interesting trade proposal I’ve heard is BP for Yunel escobar and bring up Frazier to play 2B.

Zack Cozart

Slyde, Zack uses a K in his name. I also think you are underrating him. Offensively he projects to be an average MLB shortstop to slightly above average. Defensively he is above average. He has shown outstanding plate discipline this year and skipped over High A and really didn’t miss much of a beat.

Walt Jocketty said a few weeks ago that they would like to move him up to see what they had before next year. Since it hasn’t happened yet I get the feeling its not going to this season. I think thats a pretty bad plan. The Reds need to know if he can be an option in 2010 before they go to free agency for a shortstop and either over pay, or get someone who is just going to suck because they only want to give him a 1 year deal because of Cozart and no one worth anything is taking a 1 year deal.

I'm not sure how I'm underrating him

I don’t think you’ve said anything much different that what I’ve said. Sure, he could be an average bat for a shortstop, which puts him right around a .700-.720 OPS (I’m looking at median, not average, since Hanley really throws off the curve). And typically, average hitting shortstops get most of their value from their glove (think Orlando Cabrera). This is basically what I’m saying.

Thanks for the correction the spelling of the name, but I got it from you.

Spelling

I didn’t know he used a K until this year.

As for underrating him, I guess the ‘he probably isn’t a Reds Top 10 prospect’ is what I was going with. He is easily inside the top 10. Alonso, Stubbs, Frazier, Heisey, YRod…. those are the only guys I would rank ahead of him right now in the system.

I don't want to bring him up this season

though, like Doug, I wish they had moved him to AAA. My point is that his primary skill is his glove, which is MLB ready. His bat will just have to finish developing in the Majors.

Can't link to dougs site cause I'm on my phone

But el niño destructor was promoted to AAA while Frazier (and Cozart) are stuck in AA. I won’t repeat Doug’s concerns, which I agree with. Ill add though that I think it sends a bad message when a guy with bad defense who rarely walks, strikes out a bunch and is only 22 gets promoted over guys who have great plate approaches and play good defense.

The only way this makes sense is if he’s being showcased for a trade (for Hardy maybe?)

Is it me or is the destructor

seem to be the same type of player as EdE. Especially this year. Very streaky, and the capacity to make a zillion errors.

by mrsmith35sg on Aug 15, 2009 3:25 PM EDT up reply actions   0 recs

maybe

but they are very different hitters. EdE had a decent walk rate and Francisco has much more power. The key difference being that even when he was slumping, EdE typically got on a base a little bit.

I don’t see the need to rush Francisco. Like Doug says on his site, he won’t be needed until July, 2010 at best. And he really needs to keep working on his plate discipline.

The more I think about it the only way this makes sense is if they are thinking of trading him, especially when you consider Walt wants to re-sign Rolen.

Maybe Rolen is super crazy hurt and since Francisco’s on the 40 man he’s getting a September call-up?

does this mean I'm getting banned?

I actually realized I should go in depth just after I hit “post”.

Balentien was put on the 40-man relatively early and brought onto the Mariners at 22, for all of 4 PAs.

Because he was brought up early and his options were burned, the Mariners needed to trade him before he (hopefully) blossomed. I’d assume the Ms would rather have a 900 OPS Wlad then Robert Manuel.

Bringing up Francisco this year would seem awfully similar, no? Bringing up a guy for just a few PAs in a dead season who anyone could tell you is not ready?

by Cy Schourek on Aug 15, 2009 3:41 PM EDT up reply actions   0 recs

actually

if im not mistaken, the Reds have already burned one of his options this year, no? he had to be put on the 40-man last winter to protect him from the rule-5. so when he was sent to the minors this spring it counted as one of his options.

or am i completely mistaken?

This is about Louisville and having a respectable playoff team; not on the promotional merits of Francisco or Frazier . . . even though Francisco has done enough to be promoted.

Even if they still want Frazier at 2B

I don’t see it necessary to continue to give Luis Bolivar and Eric Eymann consistent playing time when you have a player like Frazier who’s killing AA like he is. The main thing that tells me is that they don’t have nearly the confidence in him that we do.

As for the playoffs argument, I’m fine with thinking that they’d like to see the AAA team succeed, and even add players for the stretch run, but how would Frazier not help them achieve that goal? He’s certainly better than what they’ve got. (Cozart too, actually)

you really think Francisco has done enough to be promoted?

his plate discipline is still horrible (though a bit better) and he isnt making any strides on defense. im not a big believer in Francisco to begin with, but he is only 22 and still has great potential. he can mash better than anyone in the minors not named Mike Stanton, but unless the Reds handle him properly he’ll never have a chance. i get that the Bats are making a playoff push and i’ll even admit that Juan is probably the best power bat available to help out, but to say he has “done enough to be promoted” i think is a stretch.

by Charlie Scrabbles on Aug 15, 2009 6:26 PM EDT up reply actions   0 recs

More theories

They could be promoting him to Louisville not only to fill the hole left by Barker’s promotion, but also to have Francisco be able to work with the Reds AAA coaches so that he can improve in his weak areas (drawing walks and fielding).

He'll mainly be a pinch-hitter (he's lefthanded) because we're so strong from right side with Laynce Nix and Jonny Gomes, - Dusty on Barker (someone tell Dusty that Nix bats lefty)

by RedsMasochist on Aug 15, 2009 6:36 PM EDT up reply actions   0 recs

Exactly

Again, oftentimes these things aren’t based on merit. It’s about filling a slot. Barker was called up to the Reds for whatever reason, Francisco fills that middle of the order spot and keeps moving through the system.

And yes, Francisco has done enough to merit the move-up. It’s not an an outrageous decision. Who is he replacing in Louisville?

Where is Frazier gonna play in Louisville? Is he replacing Stubbs or Heisey? No. Is he replacing Dorn or Valaika? No. Could he replace Eymann? Sure, and maybe he will, but he doesn’t have that many games at 2b and it appears they want him to finish out at the position this year.

Again, it’s about slots and playing time. I also know they don’t want to mess with Louisville too much right now as they get ready for the playoffs. That’s why I was surprised by the Barker call-up.

Defensive ageing curves

Tango did a study last year on defensive ageing that’s worth a read. His methodology is, I think, more precise than Zimmerman’s. Tango’s “matched pairs” compares a player’s out conversion rate (outs per balls in play) on a year-to-year basis when he played at the same position, in the same park, with the same pitcher on the mound, and the same batter-handedness at the plate. Zimmerman just looks at UZR year-to-year, which adds subjective factors inherent in any defensive rating formula.

Tango concludes (after regressing his findings) that a shortstop’s defensive peak is between 24 and 28. The regression is significant because of the selection bias that also affects Zimmerman’s study:

The only shortstops who survive the study are those good enough (or thought to have been good enough) to play in back-to-back years. And a player who performs above the population average is likely a player who benefited from good fortune. Consider that the league-average out rate is around 12.5%, but, for every matched pair under observation, the out rate for shortstops in the first of the two years is at least 13.0%. In essence, that 13.0% contains a tinge of luck. And that luck needs to be extracted.

Before regression, Tango’s data suggests that the defensive peak is between 22 and 24, which doesn’t sound right.

I agree with some others about going with Janish, at least in early 2010. I’d rather make sure Cozart is ready to hit major league pitching by keeping him down a few months in Louisville rather than screw up his development in an attempt to save a few defensive runs.
