Kansas City, Mo. ? Don’t tell Raul Ibanez he hit .500 with 10 RBIs during Kansas City’s 5-1 homestand.

“I don’t want to know,” he said. “I don’t even want to think about it.”

Kansas City's Joe Randa, right, congratulates Raul Ibanez after the outfielder's two-run homer. Ibanez singled, tripled and homered Sunday in the Royals' 13-1 victory over San Diego at Kansas City, Mo.

Facing a San Diego staff so weakened that an infielder took the mound for the last four outs Sunday, Ibanez singled, tripled and homered and drove in four runs for the second time in three days to help the Royals rout the Padres 13-1.

The only Royals starter without a hit in the 15-hit barrage was AL batting leader Mike Sweeney, who had hit in 12 straight games and homered in a club-record five in a row.

San Diego’s Jason Middlebrook left the game with a 2-1 count on Joe Randa in the fourth inning and manager Bruce Bochy said later that the reliever would probably go on the DL with a pulled groin.

It was so bad for the Padres, infielder D’Angelo Jimenez became the first position player to take the mound for San Diego in almost three years. Jimenez, the fifth Padres pitcher, was the only one not to give up a hit.

“We pitched Sweeney pretty well but there are also eight other guys over there who can swing the bat pretty well. We just didn’t throw the ball very well at all today,” Bochy said.

Aaron Guiel and Randa drove in three runs apiece, and Jeff Suppan pitched seven innings of four-hit ball as the Padres lost for the seventh time in nine outings.

“A 5-1 homestand is just awesome,” said Ibanez, who also drove in four runs on Friday night. “Everybody’s been swinging the bats well. It’s a lot of fun.”

Suppan (7-6) went over .500 for the first time since May 25. He gave up four hits and struck out three. Julius Matos homered in the seventh, the 21st Suppan has allowed.

Ibanez, who also drove in four runs against the Padres on Friday, reached base five times with three hits and two walks. He singled in the third, hit a two-run homer in the sixth and a two-run triple in the seventh.

“I just feel like every day is a constant battle, every at-bat,” Ibanez said. “A constant grind and a constant adjustment.”

Sweeney was 0-for-3 and his average dropped from .365 to .361. He said he was not pressing to keep his homer and hitting streaks alive.

“I felt good. I just didn’t get the job done,” he said. “Raul did, though. And Joe and everybody else but me.”

Randa had a solo homer and two run-scoring singles.

The Royals scored three runs in the second off Jake Peavy (0-2) on a sacrifice fly by Neifi Perez and RBI singles by Luis Alicea and Guiel.

Peavy, making his second major league start, went three innings. He was charged with four runs on seven hits, with three walks and three strikeouts.

“He couldn’t get anything over consistently but the fastball, and they were sitting on it early,” Bochy said. “He just didn’t have it today.”

Randa, taking over the team lead with 52 RBIs, hit his eighth home run on Peavy’s 2-1 pitch with one out in the third.

Rodney Myers relieved and got Randa to fly out to right.

In the sixth, Carlos Beltran doubled home a run and Randa had an RBI single ahead of Ibanez’s two-run homer off Rodney Myers, who came in for Middlebrook.

Bochy also said right-hander Dave Lundquist would also go on the DL , with a strained right shoulder.
