CHICAGO -- Matt Thornton and his bullpen mates don't have much use for the ERA statistic. The funny thing is, ERA doesn't have much use for them either.

Despite ranking in the top six in both batting average against and strikeouts, the White Sox bullpen weighs in with a 4.41 ERA on the season. Still, Thornton isn't worried.

"As a reliever, ERA is something I don't really pay attention to, because all it takes is one pitch," Thornton said. "ERA is something you can't really pay attention to as a bullpen. You look at your WHIP, how many baserunners you're allowing, and batting average against. That's a lot more important than ERA."

The logic is that if the bullpen continues to make pitches and hold opponents to a low batting average, eventually the ERA will fall into place. The White Sox have also logged a pedestrian 89 2/3 innings pitched this year, so there is time for the ERA to come down.

"I really think we have a lot of good arms out there, a lot of guys doing a good job, so I don't see it [staying this high]," Thornton said. "I think Tony [Peña] is in the sixes right now, and in his career he's never been anywhere near that."

Teahen still the man at third base

CHICAGO -- With Jayson Nix in Sunday's starting lineup, it appeared that there might be a platoon forming at third base that would start Mark Teahen against right-handers and Nix against left-handers.

White Sox manager Ozzie Guillen dispelled that notion before Sunday's game.

"No, Teahen is my regular third baseman," Guillen said. "Right now I'm just giving him a break. He played yesterday against a lefty, but Nix needs to play. Teahen is going to be out there every day."

The start is Nix's fifth at the hot corner and his second in the last four games. Nix went 1-for-1 with three walks and an RBI on Sunday.

Floyd hopes to be latest starter to rebound

CHICAGO -- Gavin Floyd was hoping to become the third White Sox starter in three games to turn in a performance that defied his ERA coming into the game.

Floyd came up short, however, and his 6 1/3 innings and five earned runs gave him a no-decision, thanks to a good day from the White Sox offense. It was not close to the same caliber as the bounce-back performances from Buehrle and Peavy.

On Friday and Saturday, Buehrle and Peavy combined to allow just five earned runs over 16 innings -- a vast departure from the five-plus ERAs both sported when they took the mound.

"That's what we're looking for," manager Ozzie Guillen said. "I think it's making things easier. Hopefully, our offense helps them a little bit. This ballclub is created about defense and pitching, but in the meanwhile, with the lineup we have, I think we can have better production for them."

Catcher A.J. Pierzynski hopes that the pitching staff continues to build on the strong outings they've been getting recently from previously struggling starters.

"That's what we are built on," Pierzynski said. "Consistent starting pitching, one through five. Buehrle threw well, Jake threw well. John [Danks] has been great all year. Gavin was throwing well. Freddy [Garcia] has been great for us. We are going to hit, and we are going to pitch, hopefully. If we do both of those things, we will be fine."

White Sox make first visit to Target Field

CHICAGO -- Sunday's game marks the final game of a seven-game homestand for the White Sox, and they then will be going to Minnesota. But this trip isn't going to be like any of the trips the White Sox have made to Minneapolis in the past 27 years. 

There will be no more Hubert H. Humphrey Metrodome. In its stead is the glittering new Target Field, which opened its doors for the first time this season.

Manager Ozzie Guillen admitted that he will not miss the Metrodome.

"I don't care if we're going to play on the moon or another planet, as long as we don't have to go to the Metrodome," Guillen said. "Not because of the bad way we played there in the past. I think everything in that ballpark was very unprofessional."

Former Twins backstop A.J. Pierzynski, who spent parts of six years in Minnesota, is excited to play in the new stadium.

"We are looking forward to it," said Pierzynski, who toured the facility during the White Sox final trip to Minnesota last year. "It will be different. Obviously, having played for the Twins organization and coming up there in the Metrodome, it will be cool. It will be nice. The city deserves a nice stadium, an outdoor baseball stadium. They have great fans, great people there. They got what they wanted."

The White Sox hope to get started on the right foot in the new ballpark. The team was 89-114 in the Metrodome.
