New York Yankees general manager Brian Cashman said Friday it's possible third baseman Alex Rodriguez could miss the entire season while recovering from hip surgery.Cashman says "there's no guarantees in this stuff" that Rodriguez will be able to play this year.Rodriguez, 37, had surgery on his left hip last week. The team said a six-month rehab would sideline the star slugger until the All-Star break."Yeah," Cashman told WFAN radio. "I think because [of] the serious nature of the surgery and the condition that he's trying to recover from, you know, there is that chance. I can't say it's not possible that he won't be back," he said.The Yankees signed free-agent third baseman Kevin Youkilis during the off-season.Rodriguez is due $114 million the next five years as part of his record $275 million, 10-year contract. He hit .272 with 18 homers and 57 RBIs in 122 games but was benched in three of nine playoff games and batted .120 (3 for 25) in the postseason.Briefly White Sox: Chicago agreed to a one-year deal with a club option for 2014 with right-hander Matt Lindstrom. Giants: Infielder Joaquin Arias signed a one-year deal.
