Rosales' fourth homer of the season came off White Sox reliever Matt Thornton (0-2), a 1-1 pitch that was just fair to left field.
Yoenis Cespedes hit two home runs for the second time in three games. Josh Reddick also connected. All four homers were solo shots.
A's reliever Jerry Blevins got the win (5-0) while Grant Balfour earned his 14th save in as many attempts.
The A's have won six of seven and 17 of 20. Oakland is 12-2 during a 17-day stretch without a day off.
The White Sox have lost nine of their last 10 games.
