Has left fielder Eric Byrnes played his final game this season? That may very well turn out be the case after manager Bob Melvin revealed Wednesday that the Diamondbacks and Byrnes are currently giving serious consideration to the possibility of surgery to fix his injured left hamstring. A decision on the matter isn’t expected for about a week, but if Byrnes does elect to go under the knife, he will be shut down for the year. “I think you’re looking at four to six months (of recovery time) for that type of thing,” Melvin said.”
