ANAHEIM -- Ozzie Guillen announced Tuesday that the White Sox six-man rotation will be in place starting Friday for the next 20 games, running up until an off-day on June 2. At that point, the situation will be re-evaluated.

Jake Peavy gets the start Wednesday, followed by Phil Humber on Friday and then Gavin Floyd tentatively scheduled for Saturday in Oakland. Floyd will throw a side on Wednesday to test his sore right foot, after taking an Ichiro Suzuki single off that area in Saturday's victory.

Mark Buehrle completes the road trip on Sunday, with Edwin Jackson and John Danks starting the upcoming homestand against Texas. The White Sox will go one arm short in the bullpen, with that roster decision to be announced before Wednesday's game. But with the extra rest, the starters also might be counted on to go an extra inning or two or a few more pitches than usual.

"We have a plan that if you're not pitching today and it's been three days, you're going to be in the bullpen in case we need you," said Guillen of starters possibly being available on their side days.

Humber's strength as a starter forced this decision, but it's a good choice for the White Sox to have to make. There have been times during Guillen's managerial tenure when he couldn't find a trusted fourth starter, let alone having six quality arms.

"In Spring Training, Humber was coming in as a fill-in and when Peavy comes back, we all knew what we thought was going to happen," Buehrle said. "But [Humber is] probably throwing the ball better than anybody. If anybody should get bumped, it should be one of us and not him."

"Whenever they tell me I'm going to pitch, I'll be happy to pitch," Peavy said.

Quentin proud of his handling of frustration

ANAHEIM -- Since the end of the 2010 regular season, Carlos Quentin has placed a higher premium on handling the many moments of on-field failure as opposed to celebrating his equally plentiful instances of success.

Letting go of that ground ball to shortstop in the third inning or accepting that foul ball on a 3-2 fastball down the middle in the fifth was essential to Quentin being ready to go later in the game. And through approximately six weeks of the 2011 regular season, Quentin feels as if he's done a better job channeling his frustration.

"I've been a lot better," said Quentin, who is hitting .271 with eight home runs and 23 RBIs. "It's kind of like you always are aware of things that aren't going the right way. So, that's been something I've always wanted to work on, because it's the only time you get better at something, it's when something doesn't go the way you want.

"How I've handled them has been a lot better than I have in the past. I want to get better, but it's not the easiest thing for some people. Sometimes it's easier for other people. I've done well. I commend myself for it."

Quentin's raw ability has never been a question, with White sox hitting coach Greg Walker referring to his right fielder as one of the most dynamic hitters in the game when things are going right. He entered Tuesday's contest at Angel Stadium with an American League-leading 23 extra-base hits and 15 doubles, and joins the Cardinals' Lance Berkman as the only players this year with a pair of five-RBI games, with Quentin's second coming Monday.

Having that drive to succeed, put alongside the talent, also doesn't stand as a problem for Quentin.

"It's the release of what has happened in the past, letting it go, so you have a chance to succeed in the game in the immediate present," Quentin said. "It has always been my challenge to succeed.

"Leave what's in the past. Most of time, it's the immediate past, so I can have a chance to succeed in the next at-bat. I've done that better."

Santos learning how to stay prepared

ANAHEIM -- If the White Sox had their winning ways, Sergio Santos basically would be needed to work almost every day. But their closer who is not officially a closer knows there will be times when he has to compensate for inactivity.

Santos recently closed out a victory for the White Sox on May 2 at home against Baltimore, picking up his third save of the season. He didn't pitch again until working two hitless innings on Sunday at Safeco Field to pick up the victory.

Gone are the middle-relief days for Santos, where he would get an inning at the end of a blowout. Instead, in his present role, Santos threw two side sessions between his two outings last week to maintain his incredible early-season sharpness.

"I'll let five pitches go full-speed and the rest are 70 or 80 percent, just working on mechanics," said Santos of those side sessions. "I have good momentum going and I want to continue that. I don't want to take time off completely.

"You really try to trick your mind into saying I'm getting solid work here, but you still have something to work on. I try to imagine hitters in there when I'm throwing pitches, trying to get everything I can."

There's an understanding on Santos' part that a closer might throw three straight games or four times in five days and then not take the mound again for a week. Even if side sessions can't simulate game action, they are an important part to help Santos understand his new bullpen slot.

"Work depends on the outcome of the game, whereas if you are a seventh- or eighth-inning guy, you'll throw most games that are kind of close," Santos said. "This role, it's more bunches or not many. It's just saving yourself in case there are three or four days where you got out and get the call."

Pierzynski survives foul experience

ANAHEIM -- Leave it to White Sox catcher A.J. Pierzynski to use his pain during a ninth-inning at-bat to somewhat lighten the mood of Tuesday's 6-2 loss for the White Sox at Angel Stadium.

Pierzynski was facing Scott Downs when he fouled a pitch off of his right foot and limped out of the batter's box. The Angels fans, who still are not enamored with Pierzynski after the 2005 American League Championship Series, offered up a few cheers at Pierzynski's mishap.

The next pitch was fouled off Pierzynski's right shin, causing even the catcher to break a smile as he walked around. The very next pitch, fouled off by Pierzynski, caught home-plate umpire Tony Randazzo in the right foot. Pierzynski came away with nothing but a bruised right shin and a groundout to second base for his efforts.

Third to first

• Paul Konerko moved into a tie with Rocky Colavito for 67th place on the all-time home run list at 374 after going deep in Tuesday's 6-2 loss. Konerko is 13-for-28 in his last eight games and leads the American League with 28 RBIs.

• Alexei Ramirez has four hits in his last two games, compared to four hits in his previous seven.

• The White Sox stand at 14-23 after 37 games. They had a 15-22 mark at this point last year.
