4. Manny Parra
When the Brewers hired Rick Peterson, I said that his only job was to turn Manny Parra into "... something" and Rick Peterson doesn't work here anymore, so there you go.
Manny Parra is probably the most frustrating player on the Brewers' roster. As talented as any other pitcher they have, he just doesn't seem to have what it takes mentally to put it together as a starter. One day he'll look like an ace and the next he won't make it out of the first inning. He's been doing it for three years, but the Brewers were willing to give him one more shot in 2010 to finally reach his potential. To finally grab that brass ring that has been eluding him his entire career. To finally become the man we think he can be.
He didn't. Instead, he put up a 6.19 ERA as a starter and will begin 2011 as a full-time member of the bullpen. Classic Manny.
3. Carlos Gomez
When the Brewers traded JJ Hardy for Carlos Gomez, it seemed that the Brewers had found their long-term replacements for both JJ Hardy and Mike Cameron. An extremely skilled defender, with loads of speed, who just needed to figure out how to not get out so much. As things turned out, Gomez's .288 on-base-percentage led to increased play for Jim Edmonds, and when Edmonds was inevitably traded, the Brewers got another man who would steal time from Carlos: Chris Dickerson.
Nobody can doubt Carlos Gomez's talent, but at some point (much like Manny Parra) the team is going to run out of patience waiting for him to figure it all out and give another centerfield prospect a chance.
What's that? We traded Lorenzo Cain? We're stuck with Carlos Gomez for the time being?
I remember... the Alamo.
2. Alcides Escobar
Coming into 2010 Alcides Escobar was the Brewers' shortstop of the future and the main reason that JJ Hardy found his way to Minnesota. His brief call up in 2009 caused nothing but excitement among the Brewers faithful. A .300 batting average and some of the best defensive plays you've ever seen? Yes, please. Ozzie Smith 2.0 didn't really seem that far-fetched after all. We liked him so much that we mostly ignored the stories about him and his estranged wife and child. Which was so unlike us.
And then 2010 happened. Everything that could go wrong did go wrong. His .235/.288/.326 line is honestly one of the ugliest things I've ever seen (besides Alcides himself) and his defense, while excellent, didn't seem as otherworldly as it did just a year before. When Craig Counsell started to steal starts towards the end of the season, we were all relieved, and by the time he was included in the Zack Greinke trade, we hardly even noticed. The Alcides Escobar era ended with a whimper. Just like his at-bats.
