Again he wasn't jerked around. He got hurt and didn't perform. I agree about Gallo, I didn't like the signing, but Wallner would've ended up taking those at bats, don't you think?
Is this really true? What I remember is he has always gotten injured a few weeks into his MLB stints. The one time he played a little longer, he was playing hurt which tanked his overall MLB numbers. This is a tough game and when you get your chance you gotta step up.
I would call him up and get him at bats down the stretch with a possibility of making the playoff roster. Then next year keep him for depth until he either breaks through or you deal him at the deadline for next year's triumphant division winning stretch run.
I'd like to see both Wallner and Larnach get at bats down the stretch. If Larnach goes off give him a chance to continue in the playoffs. I would also stick with Wallner as well, but maybe a couple of days off to reset are in order.
