AAA Nashville wrapped up their season today, and after the game the Brewers raided their roster for three more September callups. Taking them alphabetically:
Sean Halton will be back with the Brewers for the third time this season. He's appeared in 24 games as a Brewer this season and hit .218/.271/.309, while posting a .273/.348/.460 line in 399 plate appearances for Nashville. Ron Roenicke said he'll be the primary first baseman against lefthanded pitchers, which is a pretty limited role.
Johnny Hellweg is a big leaguer for the second time after a disastrous four-game stint earlier this year. Hellweg, acquired last year in the Zack Greinke trade, was the Pacific Coast League's Pitcher of the Year in 2013 but had a hard time translating that success to the big leagues, posting a 10.97 ERA over 10.2 innings and allowing 19 hits, walking 13 while striking out just three. He's expected to start a game in the Cubs series this weekend.
Jimmy Nelson is the only one of these three players with no MLB experience. Nelson is a quick riser in the Brewer organization and represented the team in the 2013 Futures Game in the middle of a season where he carried a 3.25 ERA over 27 starts across AA and AAA. He struck out 9.6 batters per nine innings this season, but is expected to pitch out of the bullpen this September.
Nelson will need to be added to the 40-man roster before tomorrow, so at that point the roster will be full. The Brewers could still open up another spot, though, by placing Rickie Weeks on the 60-day DL.
