PEORIA, Ariz. -- James Shields essentially emptied his entire repertoire on Sunday, which isn't something you usually see from a pitcher who is making his first start of the spring.
Not willing to merely work on fastball command against the A's at the Peoria Sports Complex, Shields leaned on the stuff that will serve him during the regular season -- his fastball, changeup and curveball.
"Unless I'm working on one specific pitch, I like to go with everything. Everything is there," Shields said.
Shields, the No. 2 starter in the Padres' rotation, tossed two scoreless innings. He allowed two hits and struck out four, throwing 33 pitches, 24 of which were strikes in the Padres' 6-5 loss.
"They were fouling a lot of balls off and working the count a bit," he said. "But overall, I felt pretty good, for the most part. It's nice to get out there."
That's not saying Shields didn't have to work a little.
He allowed a leadoff single to Billy Burns, which meant he had to work out of the stretch mere minutes into the game. He even worked on his pickoff throw, as he threw over to first base on three occasions with Burns on base.
Shields, coming off his ninth consecutive season of 200 or more innings, said he feels every bit as strong this spring as he did a year ago, his first with the team.
Last season, the Padres monitored Shields' workload in spring after he threw 25 innings during the 2014 postseason and 227 innings during the regular season.
"It's nice to have rest, but I've been in the playoffs quite a bit in my career," Shields said. "I felt I was just as strong last Spring Training as this Spring Training.
"My body feels great. I think my workout regime and workout routine dictate how my body feels."
San Diego manager Andy Green was impressed with how crisp Shields' stuff looked.
"He has got an expansive repertoire where he feels comfortable with anything in any count," Green said. "From a hitter's perspective, that's uncomfortable. You never know what you're going to get, or when you're going to get it."
• Padres outfielder Travis Jankowski didn't play Sunday against the A's, but he was available after being hit in the helmet by a line drive during morning workouts. The ball caught Jankowski on the right flap of his helmet. Green said he'll likely play on Monday.
