Max Scherzer's long road back from injury has been one of the Toronto Blue Jays' most closely watched storylines this season. The 40-year-old right-hander, who missed nearly three months due to a thumb issue, spent weeks building up his pitch count in the minors before finally rejoining the Major League roster against the Cleveland Guardians.

Scherzer's greatest challenge is squeezing a few more innings out of his well-worn right arm and battered thumb.
