Bruney, Marquez extend staff to 13

BOSTON -- The addition of right-handed hurlers Brian Bruney and Jeff Marquez prior to Monday's series opener at Fenway Park gave the White Sox a 13-man pitching staff.

And White Sox manager Ozzie Guillen might not stop there.

"You give me 25 pitchers, I would take 25 pitchers," said a smiling Guillen. "That's always my philosophy."

Bruney and Marquez replaced right-handed pitcher Lucas Harrell, who was optioned to Triple-A Charlotte, and infielder Dallas McPherson, who was designated for assignment. Guillen pointed out that Tuesday's long rain delay in Texas and Saturday's 14-inning loss in Toronto left the White Sox thin in relief options.

Harrell threw four innings and 67 pitches during Sunday's 13-4 loss to the Blue Jays, making him basically unavailable for the next few days. Guillen wanted to make sure he had some support behind Jake Peavy, who was making his fourth start of 2011 on Monday.

"It's kind of hard for us to figure out to go with 13 or 12," Guillen said. "Most likely I like 12, because it gives me more flexibility on the bench."

Dunn gets a break against tough lefty

BOSTON -- Adam Dunn's 0-for-38 showing against left-handed pitchers made him a logical choice for a night off on Monday against Boston's Jon Lester, one of the game's top southpaws. Dunn continues to fight his way through a miserable start to the 2011 season, entering this three-game set at Fenway Park with a .181 average, five home runs and a Major League-high 69 strikeouts.

The accomplished slugger has survived slumps previously in his career, but has never dealt with a funk running over two months. Yet, Dunn certainly has not given up hope as to how fortunes could change sooner than later.

"Again, you're two good months away from being right on track, so it's not the end of the world," Dunn said. "If we're sitting here in September, and this is like this, then we've got problems. But we've still got four months left. I'm going to keep fighting. I promise you.

"I'm normally pretty good at not letting things affect me too much. This has been one of the tougher things for me. I don't know why it is. I know I'm coming to a new team, we're not playing very well and I feel I'm a big part of why we're not doing well. I think that weighs a little more on me than in the past.

"To get out of it, it's not going to be to sit there and put all the pressure of the world on myself," Dunn said. "It's going to be basically say, 'Go out and have fun.' I've been doing it since I was four years old. I know how to hit. I just need to show it."

Throughout his struggles, Dunn has received e-mails and calls of support from friends and one-time teammates around the game.

"You would think this is the end of the world," said Dunn with a laugh. "But that is cool, people [care] about you and don't like to see you stink. But I don't need a pep talk. I appreciate it, but I'm fine. I'll make it."

Teahen expected to play first and right field

BOSTON -- Where White Sox third baseman Mark Teahen's injury rehab assignment with Triple-A Charlotte is concerned, manager Ozzie Guillen is not worried about the number of at-bats put together by the left-handed hitter.

"More than at-bats, he needs to play more positions," said Guillen of Teahen, who started at third on Monday in the final stages of rehabbing a right oblique strain. "I don't worry about his at-bats. I want him to play a little bit at third base, a little bit at first, a little bit in right field. When he feels comfortable, we'll do what we have to do."

Teahen, who is 2-for-12 in three games with the Knights, figures to replace one of the seven relievers on the staff later this week.

Bruney likes 'fit' with White Sox

BOSTON -- Reliever Brian Bruney followed up a strong Spring Training effort as a non-roster invite with a 1.31 ERA and seven saves over 19 relief appearances for Triple-A Charlotte. The veteran hurler patiently waited for his chance to contribute at the Major League level, liking the fit he found with the White Sox.

"I really like this organization. I like the way it's run. I like the working out, the strength program and everything," Bruney said. "For me, it was a really good fit.

"To be completely honest with you, there weren't a lot of teams calling. I knew I wanted to play for an American League team and once I got to Spring Training, I was really happy with my decision. It's a job. There's still a jersey on your back. I just wanted to go down and do my job in Triple-A and continue to work on things and get better."

Third to first

• With Gavin Floyd having thrown in relief on Saturday, he will flip-flop starts with Phil Humber in this Boston series. Humber pitches on Tuesday while Floyd will pitch Wednesday afternoon.

• Brent Morel's four-pitch walk against Jon Lester in the second inning of Monday's 7-3 victory snapped his club-record stretch of 114 at-bats without a free pass to start the season. His last walk came against Lester on Sept. 30, 2010, covering 126 at-bats in between.

• White Sox pitching coach Don Cooper will miss the entire Boston series due to family reasons. Bullpen coach Juan Nieves will be on the bench.

• Carlos Quentin was hit by a pitch twice in a game for the sixth time in his career on Monday. Quentin has reached double-digit HBP for the fifth straight season.
