Manager Alex Cora said that Jansen (lat) is available to pitch in Saturday's game against the White Sox, Alex Speier of The Boston Globe reports.
Jansen was unavailable Friday due to a lat issue and missed out on a save opportunity. However, he's feeling well enough to suit up and pitch Saturday as needed. Jansen has 25 saves and a 3.70 ERA across 48.2 innings this season.
