Former Mets pitching coach Rick Peterson believes that Johan Santana's surgically-repaired knee is bothering him again.
"I know it's been reported that he's had a blister on his middle finger, and that certainly can be a major, major detriment for a pitcher," Peterson told ESPN 1050 on Monday.
"And then there's been some rumors that you hear about his knee being a little bit bothersome right now.
"And when that starts to happen, when you've got a finger issue and you have that knee issue like he had before, you really start to get a little concerned about that."
Santana has a 6.50 ERA over his last six starts, including a nine-run debacle against the Yankees on Sunday.
