Hope you drafted well. Here's a list for your late night.
Honorable mention: Don Hoak, Billy Bates, Gene Freese, Darrel Chaney, Edwin "E5" Encarnacion, #FarrrrrrDusty
5. Willie Greene (3.7 WAR)
Greene broke in with the Reds at age 20, but didn't really become a regular until his 5th season here in 1996. That was his breakout season, OPSing a career high .822. He was also pretty good in 1997, slugging 22 homers and playing all around the diamond. He'd later get traded to Baltimore, and play in Toronto and Chicago too.
4. Nick Esasky (4.9 WAR)
Exactly. He played for the Reds from 1983 to 1988, mostly at the corner infield spots. His best year here was probably '87, where he hit .272/.327/.529 with 22 homers and 59 RBI. Of course, he went to Boston and had a 30-108 year there, but that's neither here nor there.
3. Billy Myers (6.8 WAR)
Myers played for the Reds from 1935 to 1940, but only wore that number for the last two years. Still though, those were some pretty fantastic years. He finished 14th in the MVP race in 1939, hitting .281/.369/.393 that year, which isn't too bad for a shortstop.
2. Bobby Adams (14.2 WAR)
Bobby Adams might not be a household name anymore, but he spent a decade in Cincinnati as an infielder who could rake. Longevity was the name of the game with Adams, as he spent way more time here than any of the other guys.
1. Red Lucas (1.9 WAR)
With a name like that, he couldn't have played for any other team. Lucas actually accumulated 9.3 WAR in his career here, but only wore a number for the last two. The only pitcher on today's list, he led the league in complete games 3 times, including two seasons with 28. His '29 year was particularly great, as he went 19-12 with a 3.60 ERA and a league leading 1.204 WHIP.
His nickname was the "Nashville Narcissus", which is the coolest thing ever. He wins.
