Jeremy Affeldt took a flight to Philadelphia on the advice of Giants trainer Dave Groeschner to see a specialist about his stubborn left groin injury. He expected to get an MRI exam have a five-minute conversation and fly right back.

“He comes back and says 'Here are the reasons why you need surgery'” Affeldt said. “I was like 'What?'”

Affeldt underwent a procedure to repair a tear in his groin muscle and also fix a sports hernia which wouldn’t have gotten better on its own. He plans an aggressive rehab schedule and plans to be “part of the solution” next season.

He acknowledged he didn’t solve much of anything this season -- the first of a three-year $18 million extension.

“Everybody feels the need to be better but I do take a lot of responsibility for what went down” said Affeldt who was 1-5 with a 3.74 ERA and appeared in just one game after aggravating his groin injury July 20.

His 1.24 K/BB ratio was exactly half as high as the previous season and his worst since 2006.
