The Angels would love to add a front-of-the-rotation starter like Roy Halladay and they're looking hard for relief help, according to Mike DiGiovanna of the LA Times. Acquiring relievers may be easier than obtaining a top starter, because, as Torii Hunter says, "If they're shopping Roy Halladay, everybody and their momma is going to be after him."
Halladay's teammates, Scott Downs and Brandon League, have become Angels targets, along with Chad Qualls and Rafael Bentancourt. Of the four, Betancourt would presumably be easiest to pry away, as the Jays have yet to become sellers and the D'Backs already traded one late-inning reliever.
