PHILADELPHIA -- J.A. Happ has turned himself into a legitimate National League Rookie of the Year candidate.

But will he have a chance to win it with the Phillies?

Happ, who threw seven scoreless innings Sunday in Florida, has heard his name mentioned repeatedly recently in a potential trade for Blue Jays right-hander Roy Halladay. Happ is 7-0 with a 2.68 ERA this season, and there is some belief the Blue Jays would require a young Major League-ready pitcher as part of the package. Happ would seem to be that guy.

"I'm trying to do what I can to stay here," Happ said Monday. "I don't know if that's going to be enough, but I'll find out. I'm trying to do my part and that's all I can do."

Happ leads NL rookies in wins, ERA and opponents' average (.222), is second in innings (94) and third in strikeouts (65). He is the only rookie to throw a shutout this season.

His ERA is fourth-best among all NL pitchers. Only Dan Haren (1.96), Tim Lincecum (2.27) and Matt Cain (2.32) are better. His opponents' average is fifth-best among all pitchers in the NL, trailing Haren (.187), Clayton Kershaw (.193), Yovani Gallardo (.208) and Lincecum (.214).

"You guys are basically the only people that talk to me about it," Happ said of the trade rumors. "In the clubhouse here, nobody has talked about it. That's good."

The rumors will continue until Halladay is traded or the July 31 non-waiver Trade Deadline, whichever comes first.
