Talks between the Phillies and outfielder Jayson Werth on a potential contract extension have hit an "impasse," according to Werth's agent. Agent Jeff Borris told CSN Philly that he has discussed Werth's future with Phillies general manager Ruben Amaro Jr. "I've had dialogue with Ruben since the winter meetings," Borris said. "I don't want to rule out the possibility of his re-signing with the Phillies, but it would appear right now we're at an impasse." Werth's name has popped up in rumors because the Phillies signed first baseman Ryan Howard to a five-year, $125 million extension on Monday, which may limit their ability to compensate the outfielder.
