Kansas City, Mo. ? Minnesota’s Cristian Guzman is pain-free and worry-free.

It’s no wonder his hitting streak has reached 21 games.

Kansas City second baseman Luis Ordaz stretches out as he tries to get his glove on a ball hit by Minnesota's Bobby Kielty. Kielty picked up a single on the play, and the Twins won the game, 9-2, Friday night in Kansas City, Mo.

“Guzzy doesn’t worry about too many things. I’ll tell you that right now,” Twins manager Ron Gardenhire said Friday night after Guzman smacked two singles in a 9-2 victory over the Kansas City Royals.

Guzman, who scored twice, has the longest current hitting streak in the majors and the Twins’ best since Shane Mack hit in 22 straight in 1992.

“He’s just having a good time playing the game,” Gardenhire said. “The big thing with Guzzy is he’s healthy now. His body feels good. He’s having a good time because he’s able to play pain-free. He had two bad shoulders for a long time.”

A.J. Pierzynski drove in three runs and Rick Reed (12-6) won for the sixth time in seven decisions. The AL Central leaders took a 5-0 lead in the second en route to their fifth win in six outings.

Reed gave up six hits and one earned run in seven innings. He struck out five and didn’t walk anyone the 14th time in 26 starts he hasn’t walked a batter.

“It seems like every time you walk a guy, whether it’s one out or two outs, they find a way to score,” said Reed. “I figure if they’re going to score, make them earn their way.”

Jeff Suppan (8-14) lost his seventh straight decision. He pitched five innings and was relieved after giving up three straight hits in the sixth.

He was charged with nine runs on 10 hits and five walks. Suppan, who was 3-0 in one four-start stretch in May, has not won since beating Chicago, 8-6, on July 17.

“The only way he’s going to come out is by pitching,” Royals manager Tony Pena said. “We’re going to talk to him and we’re going to go from there. Walks have been a problem for him. He pitches behind the hitters.”

Minnesota outfielder Dustan Mohr was conked in the head by a foul ball during batting practice and lay on the turf a couple of minutes before walking off on wobbly legs.

“Things were a little blurry for a minute,” said Mohr, who had a big, red welt on his bald head.

Then, when pinch-hitting in the eighth, he fouled a ball off the plate which bounced back and hit him in the mouth.

“I was trying to keep my eye on the ball,” he deadpanned. “I guess I was trying to knock some sense into myself. It just wasn’t my day, I guess. Tomorrow I’m wearing a football helmet to batting practice.”

Pierzynski hit an RBI double to start the second-inning rally, then Luis Rivas hit an RBI grounder followed by RBI singles from Guzman, Corey Koskie and David Ortiz.

Pierzynski’s bases-loaded single in the fifth made it 7-2. Ortiz brought in another run with a double-play grounder in the sixth and Jacque Jones scored on a fielding error by left fielder Chuck Knoblauch on Guzman’s single.

After Raul Ibanez doubled in the Royals’ fourth, Michael Tucker tripled off the bullpen fence in right and later scored when catcher Pierzynski threw wildly to third on a pickoff attempt.

Notes: Francisco Pena, the 12-year-old son of Tony Pena, has been taking batting practice thrown by his dad for the past two days. 2B Rivas made a sparkling play on Joe Randa’s grounder in the fourth, diving to his right and throwing out the runner from his knees. Suppan made his league-high 28th start. Reed’s ERA fell from 4.24 to 4.10. AL batting leader Mike Sweeney went 1-for-4, lowering his average from .351 to 349.
