Jansen (shoulder) threw a perfect ninth inning in Friday's extra-innings loss to the Twins. He did not record a strikeout.
Jansen was said to be dealing with a shoulder issue earlier in the week, but he was available in his normal spot Friday and ended up retiring the side on 11 pitches (nine strikes). While the veteran's command and velocity have both been affected by the shoulder recently, there has been nothing to suggest the team will need to shut him down early, though that's not completely out of the question with Boston's playoff chances dwindling. Jansen is a free agent this winter.
