The D-Backs have placed outfielder Eric Byrnes on the 15-day disabled list with a strained left hamstring. It appears that this injury will haunt Byrnes the rest of the season. He has played in 52 games this season for the Diamondbacks and he is 43 for 206 (.209 avg, .641 OPS) with 28 runs scored, 6 homers, 23 RBIs and 4 stolen bases. The D-Backs have recalled 26-year old righty reliever Connor Robertson to replace Byrnes on the roster. Robertson has pitched in 32 AAA games this season and he was 5-2 with 1 save, a 3.86 ERA and a 1.19 WHIP. The Diamondbacks will really miss Byrnes whose all out hustle seems to get the team motivated.
