Kimbrel (knee) is lined up to throw 20 pitches in the bullpen Sunday, Peter Abraham of the Boston Globe reports.

EDGE Analysis

Kimbrel was seen on the field prior to Saturday's game, practicing his delivery from the mound without a ball and then throwing in the outfield. The Red Sox want him to throw two bullpen sessions and then some kind of rehab work, whether that be a simulated game or a stint in the minors, before being activated. In theory, all that could be done this week and Kimbrel could join the team on its 10-game West Coast trip, which begins Thursday against the Angels. "Whether or not Craig travels with us remains to be seen. He would be getting close to a rehab appearance. Whether it's a sim game or not, that's all to be worked out," manager John Farrell said. Whatever transpires in the coming week, it looks like Kimbrel is ahead of the mid-August return date originally laid out for him.
