MINNEAPOLIS -- In four games against the Twins this week, Tyler Flowers and A.J. Pierzynski have each been behind the plate twice. As he continues to progress, Flowers is likely to continue to see more time at catcher this month and into the 2012 season.

In 24 games (21 starts) for the White Sox, the 25-year-old Flowers has batted .227 with three home runs, 10 RBIS and an OPS of .749. Pierzynski, by comparison, had hit .288 with six homers and 40 RBIs over 110 games entering Wednesday.

"[Flowers] put himself back on the map not just for this year but next year, too," said White Sox manager Ozzie Guillen. "That's what we were waiting for."

Flowers' development has come slowly since the White Sox acquired him as one of six players in a trade with the Braves for Javier Vazquez in December 2008.

But since he was recalled from Triple-A Charlotte, Flowers has been solid in the second half for the White Sox, especially defensively.

"Now he's more hungry than he was before," Guillen said. "Signing A.J. and [Ramon] Castro back maybe opened his eyes to, 'Wait a minute, I'm getting behind.' We've been waiting for this kid for the last two years but couldn't get anything from him. Now we are."

Quentin likely to return this weekend

MINNEAPOLIS -- Right fielder Carlos Quentin took batting practice this week at Target Field for the first time since suffering a shoulder strain on Aug. 20. He could be back in action soon for the White Sox, but the question is where and in what capacity.

With the Minor League seasons having wrapped up, Quentin will not be able to go through the usual rehab process. He'll likely have to just jump right back in at the Major League level.

"Pretty good," White Sox manager Ozzie Guillen said of how Quentin looked. "I think he's ready to go out there. We need to figure out, since Minor League is over, try to figure out how to do something about it. But I like the way he's swinging. It seemed like he was pain-free."

Quentin injured his left shoulder making a diving catch in the first inning against the Rangers on Aug. 20, and was eligible to return from the disabled list on Monday when the series against the Twins began.

"Hopefully in the next couple days -- I don't think tomorrow, but maybe over the weekend -- he'll be back in the field," Guillen said.

Peavy expected to face Tigers on Monday

MINNEAPOLIS -- For now, the White Sox will move forward with a six-man rotation that includes right-hander Jake Peavy.

Both Philip Humber and Zach Stewart -- who both delivered brilliant performances in Monday's doubleheader -- are scheduled to start against the Indians over the weekend in Chicago, and Peavy is expected to follow them on Monday against the Tigers.

"I think we should keep it the same way," manager Ozzie Guillen said of the rotation. "I'm not going to throw in the towel.

"I think [Peavy] should prepare himself for his next start. I don't think there should be any problem with that. I expect him to go out there in the next start."

If the White Sox decide they're out of the American League Central race, it's likely Peavy will be shut down at that point, to avoid any further injury risk.

Peavy said after his start Tuesday night, in which he tossed 6 1/3 scoreless innings in a 3-0 win, that he felt he could continue to pitch, but would leave the decision up to the White Sox.

"I'll let those guys make that decision," Peavy said. "All I can do is be honest with them about the way I feel. Obviously, now it doesn't seem like we're playing for much."

Rios putting together solid finish at the plate

MINNEAPOLIS -- Center fielder Alex Rios entered Wednesday's series finale against the Twins with a six-game hitting streak, including a solo home run in Tuesday's 3-0 victory.

Rios has batted .423 with 11 hits in 26 at-bats while driving in three runs during the streak. Over his past 27 games (23 starts), Rios batted .288, raising his average from .206 on Aug. 2 to .224 entering Wednesday's contest.

White Sox manager Ozzie Guillen said the key for Rios has been hitting to all fields, rather than trying to pull the ball too often.

"You can see it every time Alex wants to pull the ball ... it's a ground ball somewhere," Guillen said. "But when he stays in the middle of the field, he does what he's doing right now. The last couple weeks, that's why he's been doing it."

Rios' streak ended in Wednesday's 5-4 loss, as he went 0-for-4 with a sacrifice fly. He struck out looking with the tying run at third in the eighth inning.
