Jon Garland needed a start like this.

Following a poor outing against San Diego, Garland tossed four scoreless innings to lead the Arizona Diamondbacks over the Kansas City Royals, 11-3, on Saturday.

Tony Clark went 4-for-4, while Josh Whitesell and Josh Wilson homered and drove in three runs each for the Diamondbacks.

Garland, who gave up six runs and six hits in 21/3 innings to the Padres on Monday, only got in trouble once, giving up a leadoff single to Ryan Shealy and a walk to Mike Jacobs in the second inning. The right-hander retired the next three hitters.

Arizona signed Garland in January after he went 14-8 with a 4.90 ERA last season for the Los Angeles Angels.

Royals starter Brian Bannister, who dropped to 0-2 with an 8.53 ERA this spring, gave up six runs on nine hits and a walk in 42/3 innings.

“The numbers weren’t good and so I won’t make any excuses for it, but I was aggressive and just went after guys,” Bannister said. “I’m just trying to compete against myself. I threw better than I threw against the Cubs and so I have to take a positive out of that. But the results weren’t good, so it was a frustrating day.

“I’ll keep mixing in the cutter. That’s my best pitch and my strength. Once I start rolling with that, hopefully I can get on a roll here.”

John Sumoi hit a two-run homer in the ninth for the Royals. Jacobs singled home Billy Butler, who had doubled in the seventh, for the first Kansas City run.

Notes: Royals RHP Doug Waechter had a procedure to remove part of his right middle fingernail that was causing a blister and likely will not pitch in a game for 5-7 days. “The nail cracked,” Waechter said. “One part was basically a pin. Every time I gripped the ball, it was like a pin sticking me in the side of the finger. They basically cut that out. I was going to try to pitch with it, but they told me if it got worse, they might have to take the whole nail. That’s six weeks. So I was like, ‘Hey, wait a second.”‘ … OF Jose Guillen is expected back Monday after his wife gave birth to a son in Miami. … The Royals optioned RHP Carlo Rosa and INF Tug Hulett to Triple-A Omaha and INF Mario Lisson to Double-A Arkansas. OF Derrick Robinson, INF Cory Smith and C Sumoi were assigned to minor league camp. … Royals RHP Matt Wright has not pitched since March 6 because of a strained left groin.
