Riggans' season could be finished

Catcher's recovery time after knee surgery may keep him out

BOSTON -- Reserve catcher Shawn Riggans' season could be over after having surgery to clean up an infected bursa sac in his right knee on Wednesday.

"That really needed a lot of attention quickly, so it would not become more infected so it would not become more serious," Rays manager Joe Maddon said. "[Riggans is] back in St. Pete; doctor's taking care of him right now.

"Once again, our medical group got on it very quickly and apparently it's going to be successful. It may still be up to a four-week gig in regard to rehabbing because of the severity of the injury."

Maddon conceded that Riggans' season could be over based on the projected time of recovery.

Michel Hernandez, who was selected from Triple-A Durham on Tuesday, will likely get Riggans' playing time.

"I'm probably going to lean toward him based on what I've heard," Maddon said. "First of all, the experience level, and then what I've heard about him defensively. So yes, [Hernandez is likely the guy]."

Maddon added that it's likely that Hernandez will get a start during the weekend series against the Yankees.

Hernandez, 30, was acquired from the Pirates for cash considerations on Aug. 31, joining Durham's postseason roster. He hit .266 this year with three home runs and 17 RBIs in 76 games for Triple-A Indianapolis. His only other Major League experience is five games with the Yankees in 2003.

Riggans is hitting .222 with six home runs and 24 RBIs in 44 games this season.
