Rapid Reaction: A's 5, White Sox 4

CHICAGO -- The Chicago White Sox fell 5-4 to the Oakland Athletics on Thursday in the opener of a four-game series and a seven-game homestand.

How it happened: Oakland's Adam Rosales hit a home run in the 10th inning off reliever Matt Thornton for the go-ahead run, one of four home runs for the A's on the night. The offensively-challenged White Sox did score four times in the first five innings and then didn't score again over the final five. The White Sox left the tying run at third base in the 10th inning when Adam Dunn flied out to the wall in left field on an 0-2 pitch. After Wednesday's 16-inning game, starter Jose Quintana hung in for 7 2/3 innings to help preserve the bullpen, but gave up four runs on three home runs in the process. Oakland's Yoenis Cespedes hit two of the home runs.

What it means: The White Sox showed some resiliency after Wednesday's 5-hour, 42-minute game followed by the flight from Seattle to Chicago that had them arriving in the early-morning hours Thursday. The offense, while still far from being a juggernaut, was slightly improved from what it showed during the recent eight-game losing streak before losing steam in the late innings. The White Sox have lost to the A's four times over the past seven days with three more games remaining between the teams this weekend. The A's have won 17 of their last 20 games. The White Sox have lost nine of their last 10.

Outside the box: The White Sox's continually changing starting staff is beginning to take a toll. After posting a 3.44 ERA over the first 44 games of the season, White Sox starters have posted a 5.49 EA over the last 11 games. Gavin Floyd has already been lost for the season, while in the last few weeks, John Danks has returned, Chris Sale missed a start and Jake Peavy went on the disabled list.

Off beat: The White Sox managed to pack a lot of organizational excitement into one moment as Alexei Ramirez hit a two-run single in the third inning at the same time the White Sox's first-round draft pick was being announced by commissioner Bud Selig. Talk about your coincidences as not only was Ramirez, a shortstop, delivering the two-run hit, but the White Sox were also drafting Tim Anderson, a junior college shortstop out of Mississippi.

Up next: The White Sox will send left-hander Chris Sale (5-3, 2.44 ERA) to the mound against Oakland in the second game of the four-game series. The A's will counter with right-hander Jarron Parker (4-6, 4.90) in the 7:10 p.m. start from U.S. Cellular Field.
