The Yankees have signed corner infielder Mat Gamel to a minor league contract this week, according to Baseball America's Matt Eddy. Gamel has mostly played first and third during his (brief) major league career, and while he's never really stuck in the big leagues, it never hurts to take a low-risk flyer, especially with all the injury concerns the Yankees have.
In just 106 major league games and 269 plate appearances, Gamel has hit a paltry .229/.305/.367 with a 78 wRC+. He did perform pretty well in both 2010 and 2011 at the minor league level, posting a triple slash of .309/.387/.511 with a 127 wRC+ in 2010 and hitting .310/.372/.540 with a 121 wRC+ in 2011 (both years he spent in the Brewers system). In fact, Gamel was once one of the Brewers top prospects, and Baseball America ranked him as the 34th best prospect in baseball in 2009.
Unfortunately, he never quite put it all together in the majors, and he's been out of baseball altogether since 2012. Gamel has torn his right ACL multiple times - once chasing down a pop up in 2012 and again in 2013 before injuring his knee yet again in 2014 while working out at home.
Obviously this signing probably will amount to nothing and we'll never see anything of Gamel anywhere close to the majors. Little seems to be known of even where the Yankees are considering fitting Gamel in, as first base is locked up at all three minor league levels. The best case scenario is probably him finding some at bats as the DH in Trenton or Scranton, so at least the Yankees can see if Gamel has anything left in the tank.
Fun fact: Gamel is the older brother of Yankees prospect Ben Gamel, who played outfield for Trenton in 2014.
