KANSAS CITY, Mo. — Texas Rangers right-handed pitcher Vicente Padilla tested positive for the H1N1 Type A influenza, which is commonly known as the swine flu.

Padilla traveled with the team for the series against the Kansas City Royals and was at Kauffman Stadium when the team received the lab results. Padilla was sent back to the team hotel.

The Rangers have been ravaged by a flu bug in the clubhouse, which has forced them to juggle their lineup and their pitching staff. The team traveled to Kansas City on Friday instead of Thursday to try to keep players from spreading the virus.

Padilla, who spent the recent All-Star break in his home country of Nicaragua, is the only player who has tested positive so far.

"We have submitted cultures to the health department to determine that," assistant general manager Thad Levine said. "This is the only guy who we have information back from right now. Without speculating, it's reasonable to expect that we will find that some of our other guys have it."

Levine said after talking with the team doctors and Major League Baseball officials, the club would not treat swine flu differently than the common flu. The Rangers have prescribed medication, including Tamiflu, to all team personnel who have experienced symptoms.

That's been a lengthy list. Closer Frank Francisco was the first player to get ill and he's on the disabled list with a mild case of pneumonia.

Reliever Eddie Guardado didn't come to the park for two games in Arlington because he was too sick.

"I had never missed a game for being sick in my career," he said. "My wife came and asked me if I was all right and I said, 'Why don't you just bring the gun.' That's how bad it was. I've never been like that ever."

Catcher Jarrod Saltalamacchia, infielder Omar Vizquel, outfielder David Murphy and reliever Willie Eyre also have experienced some symptoms. Saltalamacchia did not play Friday night while Murphy started at designated hitter.

Levine said the Rangers were surprised to hear about Padilla, because the right-hander has been feeling better. He missed his scheduled start Wednesday, but is still on target to start Tuesday in Arlington.

"We're taking all the same precautions," Levine said. "We just now have a label associated with one of our players that probably at the end of the day sounds a little more dire than it may be."
