The .226 BA from him isn't a problem? His complete lack of impact isn't a problem? The GIDP tonight a crunch time wasn't a problem?
One GIDP in a "crunch time" is not a problem, no. It's baseball.
His BA? Sure, if you ignore his OBP then his BA is a problem.
His complete lack of impact
He's in the two hole. He's about the best number two batter I've seen around. His approach to at-bats is completely professional, he's seeing a ton of pitches and getting on base, he's setting the table for those that comes after him.
I expect him to move down in the order at some point because Morse is choking and Zimmerman can't do it all. Then you can watch for his impact.
