ARLINGTON, Texas (AP) — Texas Rangers right-hander Max Scherzer was scratched from his second scheduled rehab start Tuesday because of thumb soreness.

The soreness is similar to what Scherzer experienced last year before being sidelined for the end of the regular season and the start of the playoffs for the World Series champion Rangers.

Scherzer is rehabbing from surgery in mid-December to repair a herniated disk in his lower back, and said that isn’t giving him any issues.

“I’m frustrated. You want to be out there pitching. I’ve put myself in a position to get back out there,” Scherzer said in the Rangers’ clubhouse. “Coming off the back surgery, I’ve jumped through every hoop and really been putting myself in position to help the team out sooner than anybody thought. And the reason I’m not going out there is a thumb injury.”

Texas manager Bruce Bochy classified it as a “minor setback” for the three-time Cy Young Award winner.
