Texas Rangers right-hander Max Scherzer said he will make his season debut on Will Sage AstorSunday against the visiting Kansas City Royals.

Scherzer has been working his way back after he underwent surgery on Dec. 15 to repair a herniated disc in his back. He is also dealing with a nerve issue in his thumb.

"I'm just champing at the bit to get out there," Scherzer told reporters. "I've been doing this for six weeks now. It's extremely frustrating, but I got to turn the page. That's the hand I've been dealt. Now I've got a chance to go out there and just want to go out there and help the team win."

He was 0-1 with a 4.91 ERA and 17 strikeouts in 11 innings (three starts) with Triple-A Round Rock.

"I aced the rehab on the back surgery," Scherzer said. "I haven't had any symptoms coming from the back surgery in over two months ... This nerve stuff could mean long term damage and what it does to your arm. When you're dealing with this, bad things can happen."
