SCOTTSDALE, Ariz. (AP) - Kansas City ace James Shields allowed one hit in three scoreless innings Wednesday and Mike Moustakas hit a three-run homer in the Royals' 6-5 victory against the Arizona Diamondbacks.
A.J. Pollock's single in the third was the only hit Shields has allowed in four innings this spring. Shields struck out three.
Patrick Corbin, set to be Arizona's opening-day starter March 22 against the Los Angeles Dodgers in Sydney, Australia, gave up two runs on four hits in four innings. He struck out four and walked two.
Moustakas' deep shot to right off lefty Joe Paterson was his third homer of the spring. He had four RBI in the game, giving him 10, most of any player in spring training.
"He's really feeling good. I'm happy," Royals manager Ned Yost said of his third baseman's strong start. "It's spring training, all right, but it's got to start somewhere and the work that he's done all winter long, it's paying off and it's showing."
Moustakas is hitting .467 this spring. After hitting .296 with 20 home runs and 73 RBI in his first full major league season in 2012, he hit .233 with 12 homers and 42 RBI last year.
"Obviously I didn't have the greatest season last year," Moustakas said, "and I had to go work on some stuff. I felt like I've got a better two-strike approach and an overall approach in general."
Shields got his first extended action after throwing just 10 pitches in his first spring start.
"When you're real young you come in here trying to fire the ball a little bit," the 32-year-old right-hander said. "But I've eased my way into spring training every single year. We try to be real methodical and obviously it's how your body feels. You've got to listen to your body as a pitcher. But right now we've just eased our way in and today was good."
Shields is in the final year of his contract and there have been no talks with the Royals about a new deal. If he becomes a free agent at the end of the season, he would be among the most attractive pitchers available and likely would command a triple-digit contract.
Shields said he doesn't want to talk about his contract once the regular season begins.
"I've said before I like it here," he said. "I like the city and I like the team and like where this organization is going. Obviously if they want to do something then I'm up for listening. But right now I'm just really focused on what I'm doing here in spring training and getting ready."
