The Phillies are expressing "concern" over Roy Halladay's rough spring training outing on Tuesday.

Halladay allowed seven runs in just 2 2/3 innings against the Tigers.

"He says he's healthy, he feels good and nothing's wrong with him," Charlie Manuel said. "It concerns me, but I've been in the game long enough that if nothing is wrong with him, just keep working with him."

Rich Dubee blamed the results on Halladay's mechanics.

"I would say there's some concern, but most of it has to do with him having no tempo to his delivery," Dubee said. "Nuances to delivery, guys fight that all the time."
