CHICAGO -- If he could have it back, Koji Uehara would have thrown a splitter.
That can't happen, though, and Uehara left U.S. Cellular Field on Saturday night saying he would go to bed thinking about what adjustment he needs to make.
Uehara suffered his second loss since joining the Rangers, giving up a go-ahead RBI double to Alex Rios in the eighth inning, as the White Sox pulled out a 3-2 victory.
It was only the Rangers' third loss in their past 13 games, and they still have a five-game lead over the Angels in the American League West.
With the score tied at 2-2 after a strong seven-inning start by Alexi Ogando, Uehara entered the game. He gave up a one-out single to Paul Konerko followed by an RBI double to Rios, which scored pinch runner Brent Lillibridge.
Uehara had an 0-2 count against Rios, but failed to close the door. He eventually threw a 3-2 four-seam fastball that hung over the plate, and Rios roped it into the left-field corner.
"It was a situation where you don't want to throw a ball," Uehara said. "If you miss your location, they'll hit it. It's how you avoid it is what pitching is all about."
Rios wasn't in the White Sox starting lineup, but came in the first inning after Carlos Quentin injured his left shoulder making a diving catch. And Rios started the day with two hits in his last 24 at-bats, but said afterward that he has never lacked confidence in his abilities.
Uehara, meanwhile, took it hard on himself, displeased with his outings so far with the Rangers. Uehara has posted a 4.32 ERA in nine appearances, allowing four runs on seven hits over 8 1/3 innings.
"I'm not convinced with my performance since I got here," Uehara said. "I've got to make an adjustment."
Asked what specific adjustment, Uehara said: "I'll think about it before I go to sleep tonight."
But it wasn't all on Uehara.
The Rangers' offense didn't get much going against White Sox starter John Danks.
Ian Kinsler homered to lead off the game, and belted a solo shot again in the third, but that was it. Danks minimized damage all night.
Texas threatened in the fourth when Nelson Cruz had a one-out double to left-center, but he was caught stealing third.
In the fifth, Mitch Moreland led off with a single and Kinsler had a two-out single later in the inning, but nothing materialized.
Still, Ogando matched Danks.
The White Sox scored single runs in the first and second off Ogando, but he ended his night with five scoreless innings.
"In the earlier innings, I made good pitches, they weren't hard-hit balls," said Ogando, who had his longest outing since July 19. "They got good breaks, but I didn't change anything after the first couple of innings."
The Rangers had a chance in the eighth with two outs. Josh Hamilton had an infield single off Chicago reliever Jesse Crain, and moved to second on a balk.
The White Sox intentionally walked Michael Young, and then ended the inning by getting Cruz to fly out to deep right field.
After the White Sox had regained the lead in the bottom of the eighth, Mitch Moreland reached on an error with one out in the ninth.
Chicago closer Sergio Santos finished it, though, by striking out Elvis Andrus and Yorvit Torrealba.
"It came down to who was going to get the two-out hit," manager Ron Washington said. "They got one, we didn't."
