New York, NY (Sports Network) - Speaking on Alex Rodriguez's recovery from recent hip surgery on Friday, New York Yankees general manager Brian Cashman admitted that the possibility of the star third baseman sitting out the entire 2013 season does exist.

During a radio interview with New York's WFAN, Cashman commented that he's optimistic that Rodriguez will meet his projected six-month timetable to return to the Yankees' lineup, but acknowledged the three-time American League MVP's availability remains uncertain at this point.

"Best case scenario, yeah, he should be back," Cashman said. "Worst case scenario he won't be back, or there might be something in between."

Rodriguez underwent an arthroscopic procedure to repair a torn labrum and bone impingement in his left hip on Jan. 16, with the Yankees initially stating that the 37-year-old would likely be sidelined until at least the All-Star break.

Cashman warned that the recovery process could take longer, however, depending on how Rodriguez's body responds to rehabilitation.

"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 [of missing the season]," Cashman said.

Cashman did say that Rodriguez, who had just 18 home runs and 57 RBI while batting .272 over 122 games last season, would "do everything in his power to put himself in the position to get back and be healthy and productive,"

Rodriguez's injury prompted Cashman to sign veteran Kevin Youkilis to a one- year contract in December, with the onetime Boston Red Sox standout slated to handle third-base duties until A-Rod returns.
