The Milwaukee Brewers announced via their Twitter account this afternoon that they have outrighted infielder Hernan Perez to AAA. Perez subsequently elected to become a minor league free agent.

Perez was once a top prospect with the Tigers, but after struggling in limited action the club cut ties with him after exhausting all his minor league options. The Brewers claimed him on June 2nd and gave the versatile infielder an extended look, especially at third base. He got off to a terrific start, slashing .338/357/.500 (on a .423 BABIP) through his first 33 games until the All-Star Break. He hit only .241/.248/.309 thereafter, eventually settling into a platoon at third base with Elian Herrera.
Overall, Perez ended up hitting .270/.281/.365 with one home run and four stolen bases in his 90 games as a Brewer. He managed only a 69 wRC+ and walked just four times in 238 plate appearances. DRS (+4)and UZR (+5.2) valued him as an above average third baseman, helping boost his fWAR total to 0.4 in 90 games.
Hernan Perez will hit the open market entering his age 25 season with five more years of club control for whomever may sign him. GM David Stearns indicated during the Town Hall Meeting that on-base percentage is something that he values in a hitter, and Perez and his 1.7% walk rate clearly don't fit into that mold. The club had obviously seen enough to know Perez wasn't going to be a part of the future.
As it stands, the Brewers 40 man roster is down to 35. The club will have to make a decision by November 20th about which prospects to add to the 40 man and protect from the Rule 5 Draft.
The internal options at third base are now down to some combination of Elian Herrera (who has won favor with the manager), Luis Sardinas, and Yadiel Rivera. Needless to say that group presents a depressing offensive upside, but there could be plenty of defensive value to be had by employing some sort of platoon using those three. That would be quite helpful to a pitching staff that will feature many hurlers that favor ground balls. There is always a chance that the club could make an outside acquisition, as well.
