The Braves have placed 20-year old lefty starting RF Jason Heyward on the 15-day disabled list with a deep bone bruise in his left thumb. Heyward has played in 71 games this season for the Braves and he is 64 of 255 (.251 avg, .821 OPS) with 41 runs scored, 11 homers, 45 RBIs and 5 stolen bases. Despite whiffing 68 times already this season Heyward is not a hacker at the plate as he has also walked 42 times this year. The Braves have activated 31-year old righty swinging outfielder Matt Diaz off the D.L. to replace Heyward. Diaz has played in 26 games for the Braves this year and he is 13 of 73 (.178 avg, .477 OPS) with 5 runs scored, 5 RBIs and 2 stolen bases. Diaz is a career .300+ hitter in his major league career so I look for him to step up soon for the Braves.
