Scherzer (forearm/ankle/thumb) expects to make his next rehab start with Triple-A Buffalo on Friday, Mitch Bannon of The Athletic reports.
The veteran right-hander made his first rehab outing with Buffalo on Sunday and threw 41 pitches across three scoreless innings. Scherzer hopes to build up to around 60 pitches in his next start, which could be his final rehab outing before being cleared to rejoin Toronto's rotation.
