"I'm not worried about the opponents right now," Thornton said. "I'm going to go out there and locate my fastball on both sides of the plate, mix in offspeed stuff a couple of times and get the first one out of the way, honestly.
"For me, it's about getting that first game, getting that good soreness out. Then, coming back for the next game and building off of it, building forward."
Thornton acknowledged that he'll have to make some good pitches in his one inning for hitters who have played a lot already and are dialed up and ready for World Baseball Classic competition. He missed one live batting-practice session this spring due to triceps soreness but never fell off schedule for his Tuesday appearance.
