Rangers manager Ron Washington seeks an experienced closer if Neftali Feliz goes to the rotation, reports MLB.com's T.R. Sullivan. Washington told Sullivan he has confidence that GM Jon Daniels can find that reliever; Tim MacMahon of ESPN Dallas/Fort Worth has quotes. Feliz recently changed his mind and expressed a preference to start, which seems to match the Rangers' choice.
Sullivan names Alexi Ogando and Mark Lowe as the "leading in-house candidates" to close, but notes that neither has much ninth inning experience. Lefties Darren Oliver and Arthur Rhodes have seen just about everything, but they're not known for closing either.
Speculating on potentially available experienced closers, Heath Bell, David Aardsma (when he's healthy), Francisco Rodriguez, and Mike Gonzalez come to mind. The Blue Jays have four relievers with closing experience in Frank Francisco (if healthy), Jason Frasor, Octavio Dotel, and Jon Rauch. Dotel and Rauch, I believe, cannot be dealt without their consent until after June 15th.
