The Milwaukee Brewers will likely be without 1B Corey Hart for the first six weeks of the 2013 season. Hart will undergo surgery on his right knee to repair a torn meniscus, which should put him on the shelf for the next 3-4 months.

Hart took over first base duties in 2012 after Prince Fielder departed for Detroit and $214 million and Mat Gamel went down with a torn ACL in May. The 30-year old former outfielder hit .270/.334/.507 with 30 home runs in 633 plate appearances last season. A recuperated Gamel is his logical replacement at first for the start of the season.

Hart is entering the final year of a three-year deal and will earn $10 million in 2013. He holds a .276/.334/.491 batting line for his career and a .354 wOBA.
