Maeda (biceps) threw a bullpen session Saturday that went well, Betsy Helfand of the St. Paul Pioneer Press reports.

Maeda threw around 25 pitches in the session, and he exclusively used his fastball and change-up. The right-hander is scheduled to throw another bullpen Tuesday, and he'll use all of his pitches in that effort. Maeda will need to throw a few more bullpens before going on a rehab assignment, but he could be back in the Minnesota rotation in the early part of June.
