Hanson a late scratch with forearm tightness

DETROIT -- About 10 minutes before game time at Comerica Park on Wednesday, Angels starter Tommy Hanson was scratched because of tightness he felt in his right forearm while throwing a pitch in the bullpen.

Hanson will be re-evaluated on Thursday morning, and the likelihood is that he will land on the disabled list, with Angels manager Mike Scioscia confirming after a 7-4 win that the team will call up another arm for Thursday's game.

Michael Roth, Nick Maronde, David Carpenter and Ryan Brasier can be called up from the 40-man roster, which is currently full. The Angels have the benefit of an off-day on Monday, which means they can push Hanson's spot in the rotation back to July 6. And since Hanson's last outing came last Thursday, his DL stint can be backdated far enough for him to pitch in that game.

"I think there's a chance," Scioscia said of Hanson going on the DL, "just because of being able to backdate it and see where he is."

The Angels are already without Jason Vargas, who's out until late July after undergoing surgery on Wednesday to take care of a blood clot in his left armpit area. Hanson, limited to nine starts after missing nearly four weeks on the bereavement list, warmed up in the bullpen before feeling tightness in his forearm and shutting it down.

Billy Buckner, who recorded the final two outs in Tuesday's 14-8 win, filled in for Hanson and went three-plus innings. Five relievers -- Dane De La Rosa, Scott Downs, Michael Kohn, Kevin Jepsen and Ernesto Frieri -- held the Tigers to one unearned run the rest of the way.

Hanson had already left by the time the visiting clubhouse was open to the media late Wednesday night.

"It happened pretty quickly," Scioscia said. "It happened on one pitch. He felt a little tightness and just had to shut it down."
