39-year-old Texas Rangers right-hander Max Scherzer, a three-time Cy Young Award winner, is gearing up for a minor league rehab start on Wednesday following back surgery during the offseason. This will be the first time he sees game action since the surgery.

Scherzer is slated to start for Triple-A Round Rock against Salt Lake at home. The plan is for him to throw around 50 pitches against the Los Angeles Angels’ affiliate team, after throwing 40 pitches in a simulated game last Friday. Rangers manager Bruce Bochy and Scherzer are both on board with this plan.

The surgery on December 15 was to address a herniated disk in Scherzer’s lower back, which caused him to exit Game 3 of the World Series after just three innings due to back discomfort. An MRI post-World Series revealed some inflammation in the back, followed by nerve pain in his leg, leading to two epidural injections. Another MRI then confirmed the herniated disk.

Last summer, Scherzer was traded to the Rangers and went 4-2 with a 3.20 ERA in eight starts before missing the rest of the regular season and the initial playoff rounds due to a strained muscle in his right shoulder. With 3,367 career strikeouts, he is the leader among active pitchers, ahead of Justin Verlander by 21 strikeouts. Scherzer also ranks second in wins and games started among active pitchers.
