KANSAS CITY -- The Royals aren't quite certain how many outfielders they might be without for Wednesday night's game against the Yankees.

Center fielder David DeJesus' ankle remains sore, and the Royals didn't know if he would be healthy enough to play.

However, the stay of right fielder Jose Guillen's 15-day suspension has been extended through Tuesday, the Commissioner's office announced on Wednesday, and he is expected in the lineup.

Manager Trey Hillman said the Royals were ready with other options. Presumably, that includes calling up Mitch Maier or another outfielder from Triple-A Omaha.

Hillman said there are no plans to put DeJesus on the disabled list. He hasn't played since Opening Day on March 31.

"Joey Gathright has done a really good job of filling in in center field for David," Hillman said. "He's made a couple of really nice catches -- one in the left-center-field gap against Detroit and one against Minnesota, banging into the 'baggie' the other day in the right-center-field gap."

Pitching matchup
KC: RHP Zack Greinke (1-0, 1.29 ERA)
Greinke pitched a strong seven innings on Thursday, as the Royals completed a sweep of the Tigers. He gave up six hits and just one run, a solo homer. Greinke worked through a solid lineup and twice wiggled out of one-out, two-on jams. He planned his attack carefully, giving the Tigers more fastballs after they had seen Brian Bannister throw a lot of offspeed pitches the previous day. Greinke follows Bannister again against the Yankees. Greinke will probably need some planning here, too; the Yankees pummeled him for an 11.05 ERA in four outings last year.

NYY: RHP Ian Kennedy (0-1, 23.14 ERA)
Kennedy will be looking for better results his second time around after the Rays rudely greeted him on Friday in New York. Kennedy could not make it out of the third inning, as Tampa Bay tagged him for six earned runs in 2 2/3 frames, including a five-spot in the third. Kennedy said that it had been his worst outing since a similar game in the Hawaiian Winter League. The 23-year-old right-hander will be making his fifth career start against the Royals, a team he limited to two runs over five innings in a no-decision last Sept. 6.
