RR says #Brewers Corey Hart will undergo surgery on left knee and is out for the season.— Joe Block (@joe_block) June 28, 2013
This news isn't a complete shock after hearing that Hart needed to get a second opinion on his knee. He had already been out since getting surgery on his right knee in the offseason, and now his left knee will need surgery as well. The Brewers had hoped to count on Hart for their offense, as he was coming off a 30 HR season where he batted .270/.334/.501. However, his health ended those plans for 2013.
The question now is what the Brewers will do with Hart in the offseason. He will be a free agent at the end of the season, and after missing a whole year due to knee surgeries, his value will have declined. The Brewers could decide to sign him to a new deal, but Jaymes Langrehr of Disciples of Uecker points out that at age 32, this is his third knee surgery in two years. Hart will need to prove his health again, and a one-year deal will probably be the best way to do it. The question is if that deal will be with the Brewers or someone else.
