DETROIT -- The White Sox added a veteran reliever on Saturday in Brett Myers, who recorded 19 saves this season for the Houston Astros before being traded.

But Myers' arrival on Sunday in Detroit will only add to the setup excellence in front of closer Addison Reed, not supplant the rookie from his job.

"This is in no way a sign that anyone is wavering on Addison Reed and our confidence in him," White Sox general manager Ken Williams said after sending two Minor League pitchers to Houston for Myers. "Ultimately, the ninth inning is [manager Robin Ventura's] call."

After Saturday's 7-1 loss to the Tigers, marking a fourth straight setback for the White Sox and a drop into second place in the American League Central, Ventura made that call in favor of Reed.

"Reeder is still going to be closing," said Ventura of the bullpen alignment. "Right now, [Myers] is probably in there doing the same stuff as Jesse [Crain].

"There's the option to move him around and do a lot of different stuff. But for me right now, Addy has really earned the right to do that. He's going to be the one doing that."

Reed has 15 saves in 18 opportunities but is coming off of his toughest blown save of the year, which came on Thursday, when Red Sox outfielder Cody Ross launched a walk-off three-run shot at Fenway Park. The 23-year-old Reed has shown great resilience and fortitude in handling this job, through the ups and downs.

De Aza just what White Sox need in leadoff man

DETROIT-- Between stops at Triple-A Charlotte and with the White Sox, Alejandro De Aza played in 153 games last season.

On Saturday, De Aza took part in his 92nd game of the 94 played by the White Sox this season, meaning he once again should be in the 150s at the end of the year, barring an injury.

The numbers seem similar in terms of endurance, but De Aza explained on Saturday that there is a difference.

"I'm not going to say more pressure because pressure, if you're going to have pressure, you're going to have pressure here, down there or anywhere," De Aza said. "But the expectations? Yeah.

"It's the same, but at the same time, it's kind of different. It's the same baseball, but because it's a different level, you have to try to not make many mistakes. That makes it a little bit different."

De Aza has been the consummate leadoff man and center fielder since taking over the role at the start of the season. He has provided the added bonus of six homers and 37 RBIs, including a two-run drive off Justin Verlander in Friday night's 4-2 loss to the Tigers.

In that instance, though, De Aza was simply trying to make contact and advance Alexei Ramirez from second base to third. He also saw 14 pitches in his first two at-bats, helping to drive up Verlander's pitch count.

"For leading off and being able to take pitches and doing all the things he's been doing, playing center field, and for this being the first year he has done it, it's a tough spot," White Sox manager Robin Ventura said. "But I like what he's done for us.

"He's not afraid to get deep into a count and take some pitches. Between him and [Kevin Youkilis] batting second, guys should be able to see a lot of pitches by the time they come up."

Crain returns to Sox from DL; Floyd to follow

DETROIT -- White Sox right-handed reliever Jesse Crain was reinstated to the active roster from the 15-day disabled list prior to Saturday's game against the Tigers at Comerica Park. Right-handed reliever Brian Omogrosso was optioned to Triple-A Charlotte.

Crain had been on the DL retroactive to June 24 with a right posterior shoulder strain and was expected to possibly return on Sunday, but the White Sox felt confident enough in his recovery to push him up one day.

"It's just one of those that we wanted to get back to normal as quick as possible," manager Robin Ventura said. "He felt fine, so it's time to make the move. Get our guys used to being in there in situations to be ready."

Ventura added that right-hander Gavin Floyd is set to return from the DL on Monday night and start Chicago's series opener against the Twins. Getting Floyd back from his right elbow tendinitis will move the White Sox closer to full strength for the final two-month stretch run.

"We are kind of getting ourselves closer to being back to normal, [in terms] of who we had when we left Spring Training," Ventura said.

As for Omogrosso, who produced a 4.26 ERA over five games since he was called up from Charlotte, a sample of the big league experience leaves him desiring even more.

"I'm on that borderline right now," Omogrosso said. "There are still a lot of aspects I can work on to make myself a better pitcher. Hopefully, once I do that, I can stay up here for a good while."

Third to first

• White Sox head athletic trainer Herm Schneider and Ventura visited the mound to check on Chris Sale during the third inning of Saturday's 7-1 loss to Detroit. Sale had walked Gerald Laird and Danny Worth on nine pitches to open the inning and had taken a Jhonny Peralta single off his left hand in the second.

But there was no need for concern, as the southpaw stayed in the game to work seven innings.

"A.J. [Pierzynski] had walked out and looked in the dugout -- that's why he went out there," Ventura said. "He said he's fine. We just let him go."

"Everything was fine," Sale said after taking a loss for the first time since May 12 and losing for the first time following a White Sox defeat. Sale had won eight straight decisions. "My arm felt good, body felt good."

• Dylan Axelrod, who gave up two runs in the eighth inning on Saturday, was optioned to Triple-A Charlotte after the loss. The rookie was 1-2 with a 5.63 ERA, splitting his time between six starts and four relief appearances.

• Adam Dunn is 1-for-23 in his last six games.
