Perez likely to miss a few games with sore hand

KANSAS CITY -- Royals catcher Salvador Perez might miss the last two games of the White Sox series after leaving Monday night's 7-6 loss with a sore and swollen right hand.

The injury occurred previously and was aggravated as he batted on Monday night. X-rays after the game were negative.

"Salvy two days ago got jammed real bad on his right hand," manager Ned Yost said. "He had a couple of swings today that made it worse. It was real sore and real swollen, so it'll probably be a couple of days.

"We'll just rest it for a couple of days and try to get some of that inflammation and swelling out."

Perez was replaced by backup Brett Hayes for the ninth inning.

Herrera, Ventura excited to host equipment drive

KANSAS CITY -- Kelvin Herrera remembers when his love of baseball in the Dominican Republic wasn't accompanied by very much equipment.

Herrera didn't get his first baseball glove until he was about 11. What did he do before that?

"I asked friends, 'Hey, can I use your glove for a couple days?'" Herrera said. "And then my aunt's husband sent me one from New York. I remember it was an Easton, a pitcher's model. It lasted me for like six years."

That's why the Royals, along with Herrera and fellow Dominican pitcher Yordano Ventura, are teaming up with the Baseball Tomorrow Fund to host the annual Royals Equipment Drive. The drive will be held at Tuesday night's game against the White Sox at Kauffman Stadium.

Fans can contribute new or used equipment from 6 to 7:30 p.m. CT on Tuesday outside the Diamond Club on the Field/Plaza Level. Cash donations also are accepted. Fans can get an autographed baseball for a $40 donation or an autographed photo card for a $10 donation while supplies last.

Herrera and Ventura presented a check for $5,000, a BTF grant, to Cristo Rey Kansas City for the purchase of new equipment before Monday night's game. Cristo Rey, beneficiary of this year's drive, is in a national network of 26 schools developed to lift urban youth from poverty by providing a college preparatory education.

"Like me and Ventura, if you receive a little help, it makes things better," Herrera said.

Herrera and Ventura remembered making the most of what little equipment they had.

"For a team, we used just one bat. And it was for both teams," Herrera said. "We used maybe three baseballs and you know when they get wet, they get heavy. So we had to dry them in the sun. Then when you pick it up and rub it, the leather feels like concrete. So that was tough but, as a kid, you enjoyed it. You just wanted to play."

Broken bats were held together with nails and black electrical tape. Torn gloves were stitched together time and again. And baseballs, well, they often were made by the kids themselves.

"I made baseballs with a sock and foam from a mattress. I'd wrap it real tight and put tape around it and it became a real baseball," Herrera said. "And we used to use doll heads for baseballs, too. You cut off the hair and it became a baseball. We used little plastic bottles for baseballs, too. That's how we did it in the Dominican. Anything you could hit."

But if those sock-and-foam balls happened to land in the water?

"Oh, you had to really squeeze them out and then you could play," he said.

The youngsters who benefit from this drive won't have to do that.

"We like to help these kids get this equipment, because I know they're going to use it and they're going to enjoy it," Herrera said.

Adjustment by Butler results in three-hit game

KANSAS CITY -- Billy Butler's first three-hit game of the season on Sunday came after hitting coach Pedro Grifol straightened out a flaw in the designated hitter's swing, according to manager Ned Yost.

"He just had a little mechanical adjustment that he needed to make," Yost said. "He and Pedro figured out what it was a couple of days ago, and he's swinging the bat much better ever since.

"His back elbow was kind of coming out and around, and now he's keeping it tucked underneath him and driving it. It's a very simple adjustment, but it's paid pretty good dividends."

It paid off again on Monday night as Butler went 3-for-5 in a 7-6 loss to the White Sox. That makes him 7-for-13 in the last three games.

Gordon joins rare Royals company with huge game

KANSAS CITY -- Alex Gordon's smash hitting display in Sunday's 8-6 victory over Baltimore was the fifth of its kind in Royals history.

Research shows that only four other Royals had games with at least four hits, two home runs, six RBIs and three runs scored.

Gordon was the first since Kevin Seitzer had six hits, two homers, seven RBIs and four runs on Aug. 2, 1987, against Boston.

The others were George Brett (four hits, three homers, seven RBIs, three runs against Detroit on April 20, 1983), U.L. Washington (four hits, two homers, six RBIs, three runs against Oakland on Sept. 21, 1979) and Willie Wilson (four hits, two homers, six RBIs, four runs against Milwaukee on June 15, 1979).

Infante takes BP, still dealing with back inflammation

KANSAS CITY -- There's still nothing decided on the return of second baseman Omar Infante, who took batting practice on Monday as he recovers from back inflammation.

"It's not really the rotation [while swinging] that's bothering him, it's bending over where he still feels it a little bit fielding ground balls," manager Ned Yost said.

Infante, out since May 7, might go out on a Minor League rehabilitation assignment before getting back into the Kansas City lineup.

"Yes, he could for a day and get him six or eight at-bats maybe," Yost said. "But we haven't discussed it."
