KANSAS CITY, Mo. - Saturday night wasn't the start of an offensive breakout after all.

And Chris Capuano certainly didn't seem like any sort of answer for the rotation.

Looking very much like a team playing its 17th game in as many days (and 38th in 40), the Yankees barely registered a pulse Sunday afternoon, doing little at the plate and playing sloppy defense in a 6-0 loss to the Royals in front of 31,251 at Kauffman Stadium.

"We have to turn the page," said Alex Rodriguez, who went 1-for-4, barely missing a home run and settling for a double in the fourth after Edinson Volquez set down the first 11 batters he faced.

The Yankees (22-17), who fell to 2-5 on this nine-game, three-city trip and have scored 11 runs in their last six games, are off Monday before starting a two-game set against the surging Nationals Tuesday night.

"We've played 30 out of 31 [days]," Joe Girardi said. "The week didn't finish the way we wanted it, but you look at our record in that long stretch (19-11), it's pretty good. So I think this off day's really important to our guys physically."

Volquez (3-3, 2.74) encountered little resistance. The righty allowed three hits and no walks in seven innings, striking out five.

"As good as I've ever seen him," Mark Teixeira said.

Teixeira left the game in the seventh inning with a right big toe contusion, suffered when he was hit by a pitch in the fourth inning. X-rays were negative.

"As the game went on, it really got sore, so I was a little concerned," said Teixeira, who expects to play Tuesday night. "I'm just thankful now."

Capuano, out with a quadriceps injury suffered in his first spring training start, was not good, allowing two walks and two singles to the first four batters in the fourth inning before being pulled. The 36-year-old lefthander, signed to a one-year, $5-million deal in the offseason, was charged with four runs and allowed four hits and two walks in three innings-plus. "Certainly not the outing I wanted my first outing," he said.

Salvador Perez put the Royals (24-14) on the board in the second, hammering a full-count changeup into the Kansas City bullpen in left for his fifth homer and a 1-0 lead.

Capuano's afternoon quickly unraveled when he issued back-to-back walks to Lorenzo Cain and Eric Hosmer to start the fourth. When Kendrys Morales singled to right, Carlos Beltran might have had a play at the plate on Cain but instead soft-tossed the ball into second. After Perez rocketed an RBI single to left to make it 3-0, Girardi had seen enough, bringing in Esmil Rogers.

Omar Infante greeted the righthander by pulling a fastball down the third-base line for an RBI double that put runners on second and third. Rogers was able to escape without any further damage.

"The first three innings felt really good, and I think I got away from my aggressive approach," Capuano said. "The two leadoff walks came back to hurt me. It's frustrating."

Omar Infante reached on Chase Headley's throwing error to start the sixth, leading to two unearned runs against Rogers that made it 6-0. It was Headley's team-worst eighth error and gave the Yankees 28 errors, third-most in the AL.

"It's a play I feel I should make 100 out of 100 times," Headley said. "I just need to shore up the consistency. It's not catching the balls, it's just been some throws. I'll get it cleaned up."
