PHILADELPHIA – Roy Halladay will try to change his fortunes with a new catcher when he takes the mound tonight.

Humberto Quintero – and not Erik Kratz – will start at catcher for the Phillies when they host the New York Mets at 7:05 p.m.

Halladay’s struggles have been one of the biggest Philadelphia storylines this young season.

The ace finished 11-9 last season. He struggled in spring training with a 6.06 ERA. Halladay allowed six hits and five runs in 3.1 innings in his first start last Wednesday against the Atlanta Braves.

The speculation is that Halladay didn’t like throwing to Kratz. Halladay made some comments to reporters in Atlanta that indicated he and Kratz were not on the same page. Halladay did not directly criticize Kratz.

But Phillies manager Charlie Manuel knocked down those theories this afternoon. He said Halladay never complained about Kratz. The manager said he simply wants to see Quintero work with Halladay. Manuel also said Kratz will catch Cliff Lee on Tuesday.

Phillies regular catcher Carlos Ruiz is in the midst of a 25-game suspension for violation Major League Baseball’s performance-enhancing drug policy.

The Mets will start 24-year-old Matt Harvey, who struck out 10 and allowed no runs in seven innings in his first start.
