Having been in a similar situation two years ago Joba Chamberlain has been following the Matt Harvey elbow saga. Like Harvey Chamberlain really never felt pain in the elbow that was diagnosed as a torn medial ligament which is different than Harvey’s tear in the right ulna collateral ligament. “I could turn a doorknob and rub my head and people said I couldn’t do that’’ said Chamberlain who like Harvey was examined by Dr.James Andrews. “[Andrews] said he didn’t operate on healthy arms.’’ Chamberlain long tossed was a little sore and told Andrews he wanted to have Tommy John surgery. “For me it was a matter of getting it done and knowing it was fixed’’ Chamberlain said of the June 2011 surgery. Harvey has opted to avoid surgery and hopes a six- to eight-week throwing program will help him stay away from Andrews’ scalpel. “Everyone is different and I hope the best for Matt. Maybe he is the exception to the rule like [Roy] Halladay was’’ Chamberlain said of the Phillies right-hander who opted for no surgery on a similar problem. “I just hope Matt is mentally where he needs to be.’’ Manager Joe Girardi said he is looking forward to getting a big piece of the bullpen back Friday night against the Giants. Boone Logan who hasn’t pitched in a game since Sept. 6 because of a bone spur in the left elbow that was discovered Monday threw a bullpen session Wednesday at Rogers Centre. “My hope is yes but it really all depends on how he feels [Thursday]’’ Girardi said of Logan being available. “If he feels good tomorrow then I would say he’s a player for us Friday.’’
