Scherzer (shoulder) will start Saturday's game against the Mariners, Shawn McFarland of The Dallas Morning News reports.

Scherzer appeared in a rehab game with Triple-A Round Rock on Saturday, during which he threw four shutout innings while striking out eight batters and walking one. Following his elite performance, the 40-year-old righty is now slated to make his first start in the majors since July 30, and he'll have the luxury of being welcomed back by a Mariners offense that ranks 25th in MLB with a .675 OPS on the season.
