Wikipedia says it is "a common injury in baseball players." Notable cases Jose Canseco, Oakland Athletics outfielder (1989) Ken Griffey, Jr., Seattle Mariners outfielder (1996) Jim Thome, Cleveland Indians first baseman (1996) Eric Hinske, Atlanta Braves first baseman (2003) Ryan Kalish, Boston Red Sox outfielder (2007) Dustin Pedroia, Boston Red Sox second baseman (2007) Troy Tulowitzki, Colorado Rockies shortstop (2010) Domonic Brown, Philadelphia Phillies outfielder (2011) Pablo Sandoval, San Francisco Giants third baseman (2011, right; 2012, left) Nick Markakis, Baltimore Orioles outfielder (2012) So hopefully Choi just sucked.
