Max Scherzer Injury: Tracking toward rehab start Friday

Scherzer (thumb) is tentatively scheduled to begin a rehab assignment with Triple-A Buffalo on Friday, Ben Nicholson-Smith of Sportsnet.ca reports.

Scherzer had a successful 50-pitch simulated game Sunday and will throw a bullpen session Tuesday or Wednesday. Assuming he comes out of that without a setback, he'll be cleared for a formal rehab start Friday. Scherzer is slated for 60-to-65 pitches in the outing with Buffalo and would require at least one additional rehab start after that before returning from the 60-day injured list. The 40-year-old has been out since late March with right thumb inflammation.
