Once again, another no-brainer.
5. Mark Watson (0.0 WAR)
Here's the token 2003 guy. 2 innings. There you go.
4. Chris Bushing (-0.2 WAR)
Bushing got his shot in 1993, with 4.1 innings (and 6 runs given up). He was actually called up from Chattanooga, and was at one time traded for Nick Capra. Now you know!
3. Giovanni Carrara (-0.2 WAR)
Here's a guy who actually played a long time, only briefly for the Reds, though. He ended up making 2 starts for the Reds in 1997 using that number, and spent '96 wearing #40, where he had 5 starts. I think he's most well known at this point for being a reliever for the Dodgers in the early to mid 2000s, but he had a little bit of Reds time too.
2. Gary Redus (-0.4 WAR)
He ended up accumulating 5 WAR over the 4 seasons he was with the Reds, and the speedster Redus is one of the most memorable players from the early 1980's. He wore #61 in his rookie season, where he had 89 AB in the 1982 season.
1. Bronson Arroyo (21.5 WAR)
Duh. The Nasty Hook might be the first shoo-in Reds hall of famer on this list, and for good reason. Arroyo (likely) ends his Cincinnati career with a 4.05 ERA in 8 seasons with the team, and almost amassed 1500 strikeouts. I have a feeling that Arroyo is one of those players that this generation of Reds fans will end up telling their grandkids about. Never missed a start, and was as consistent of a performer as you'd ever see. Personally, I hope he liked the city enough to return as a coach someday, but I bet he'll end up in the press box before he does that.
