Standing in the visitors’ clubhouse in Atlanta a week ago, Roy Halladay mentioned many reasons for his struggles in his 2013 debut. He blamed his location, he partially blamed the weather, and he hinted at some communication problems with catcher Erik Kratz.

Halladay made his second start of the season Monday against the Mets. Interestingly enough, Kratz was not in the starting lineup.

Humberto Quintero caught Halladay Monday. Phillies manager Charlie Manuel said the swap was nothing more than giving Kratz a break.

“(Kratz) caught yesterday, he’ll catch tomorrow,” Manuel said. “Q caught a good game the other night and he’ll catch Halladay tonight.”

Kratz seemed to take it differently.

“There’s one thing that’s consistent out there and it’s me,” Kratz said. “I have to look at myself and look at how we’re doing back there and if I can’t help the team improve then put (Quintero) back there. I have to do a better job.”

Quintero did not catch Halladay this spring, only in bullpen sessions. As an 11-year veteran, Quintero didn’t seem too worried about adjusting to Halladay.

The communication problem between Kratz and Halladay was likely centered on one pitch, a low fastball to Justin Upton in the first inning of the Phillies’ 9-2 loss to the Braves. Upton clobbered the pitch over the right-center field fence.

Halladay said he wanted to pitch up and in, but Kratz’s target was low. He called the pitch “half-hearted.”
