Hart's injury puts Gamel back into the mix as the starting first baseman. The 27-year-old was initially being slated to be bench player for the Brewers this season while working his way back from that knee injury. He hit .246 with one homer in 21 games last season before going down on May 1. He missed the final five months of the season but is expected to be back at 100 percent when the Brewers report for spring training in February.
A fourth-round draft pick in 2005, Gamel has played in just 106 games since making his major league debut in 2008.
