Warren, relievers implode as White Sox tee off on Yankees

Joe Girardi knew last night might not go smoothly.

“In a major league debut, you never know what to expect,” the manager said before the game.

Adam Warren’s did not go well.

And for one night, at least, the Yankees showed how much they could miss Andy Pettitte and CC Sabathia in a 14-7 loss to the White Sox.

“I wouldn’t make too much of it,” Girardi said after watching his makeshift pitching staff get beaten up. “It was a bad night. Everyone has them. I wouldn’t be too quick to form a judgment.”

It’s hard not to, since the Yankees are going to be forced to rely on some pitchers who are either inexperienced or inconsistent now that Pettitte (fractured left leg) and Sabathia (groin) are out until after the All-Star break.

BOX SCORE

Warren was the first starter to fill in for Sabathia, and after he held the White Sox scoreless in the first inning, the Yankees gave the 24-year-old four runs in the bottom of the inning.

“I felt good about my stuff at that point,” Warren said. “I had a sigh of relief getting through that first inning. In the second inning, I found it hard to find my rhythm.”

He was knocked out in the third after giving up six runs in 2 2/3 innings and replaced by David Phelps, who is in good position to take Warren’s spot in the rotation with Freddy Garcia scheduled to start for Pettitte on Monday.

“He looked pretty good to me,” Girardi said of Phelps, who had been in the minors trying to become a starter again after spending time in the Yankees’ bullpen. “When we sent him down, he just hadn’t pitched a lot, and that wasn’t something we wanted from him, because we really believe he’s in our future plans.”

Those plans could start as soon as Wednesday, though Girardi wasn’t ready to make any announcements after last night’s debacle.

The Yankees tied the game at 6-6 in the fourth, but the game quickly unraveled. While Phelps (1-3) got the loss — he gave up A.J. Pierzynski’s leadoff homer in the fifth that put the White Sox up for good — he wasn’t the main culprit out of the pen.

That was Cory Wade, whose horrific run continued as he surrendered six runs in 2 2/3 innings, just like Warren.

”He’s just not locating well,” Girardi said of Wade, whose ERA has shot up to 5.79. “He’s up in the zone.”

He was so bad, Dewayne Wise — the outfielder — had to come in to clean up the mess. Wise mercifully managed to get the final two outs of the inning and the Yankees’ bats went quietly in the ninth.

Warren figures to be headed back to Triple-A Scranton/Wilkes-Barre with the Yankees needing someone else to eat up innings in case another starter falters. D.J. Mitchell is a possible replacement, since he’s already spent time in The Bronx this season.

With last night’s implosion, the Yankees are even more reliant on veterans like Hiroki Kuroda, who heads to the mound today hoping to help the team avert a three-game losing streak.

”Hopefully somebody comes up big,” pitching coach Larry Rothschild said after Sabathia and Pettitte went down Wednesday.

The Yankees likely have to hitch those hopes to Garcia and Phelps.
