Yankees' Chien-Ming Wang out until September

New York Yankees pitcher Chien-Ming learned Monday that he will be sidelined until at least September because of an injured right foot.

New York Yankees pitcher Chien-Ming Wang's foot injury is worse than first feared.

Wang, 28, learned Monday that he will be sidelined until at least September after tests revealed a partially torn tendon in his sprained right foot.

He must use crutches and wear a protective boot for the next six weeks.

New York's pitching staff has been decimated by injury, with Brian Burney, Phil Hughes, Ian Kennedy and Wang on the shelf.

"It is a manager's worst nightmare when a pitcher is on a basepath," Yankees manager Joe Girardi said. "It is unfortunate."

Wang hurt the foot as he ran the bases in Sunday's 13-0 interleague victory over the Houston Astros, who, as a member of the National League, don't subscribe to the American League's use of a designated hitter.

"The National League needs to join the 21st century," Yankees co-chairman Hank Steinbrenner fumed. "They need to grow up and join the 21st century.

"Am I [mad] about it? Yes. I have got my pitchers running the bases and one of them gets hurt. He is going to be out.

"I don't like that and it is about time they address it. That was a rule from the 1800s."

Wang suffered the injury as he rounded third base on Derek Jeter's sixth-inning single, hobbling home to score and doubling over as he crossed the plate.  

"We don't hit, we don't run the bases," Yankees pitcher Mike Mussina said of AL pitchers in general. "You get four or five at-bats a year at most and, if you happen to get on base once or twice, you never know.

"We run in straight lines most of the time. Turning corners, you just don't do that."

"This is always a concern of AL teams when their pitchers have to run the bases and they're not used to doing it," Steinbrenner said. "It is not just us — it is everybody.

"It probably should be a concern for NL owners, general managers and managers when their pitchers run the bases. Pitchers have enough to do without having to do that."

Wang has pitched well this season, posting an 8-2 record, including 5-0 on the road, with a 4.07 earned-run average in 15 starts.

The Taiwanese right-hander is 54-20 with a 3.79 ERA, four complete games and one save in 97 appearances (95 starts) since he made his major-league debut with the Yankees on April 30, 2005.
