Piscotty hit a two-out double in the eighth inning, and Martini singled him home to put the A's in front. It was Martini's first career hit in the big leagues, a clutch single up the middle.
Oakland reliever Blake Treinen got Matt Davidson to ground out into a game-ending double play to pick up his 17th save and secure the win for the Athletics, who bounced back from a Friday night loss to the White Sox with their sixth victory in their last seven games.
Tim Anderson's three-run home run highlighted a five-run first-inning for the White Sox. Jose Abreu and Kevan Smith each had RBI singles in the frame as Chicago jumped out to a 5-0 lead.
The A's chipped away at the deficit. Piscotty hit his sixth home run of the season, a two-run shot in the second inning.
Oakland has hit a home run in 24 consecutive road games, tying the major league record set by the 1996 Baltimore Orioles.
Jed Lowrie's two-run double drove home Jonathan Lucroy and Franklin Barreto to the tie score at 5 in the fifth inning.
Olson's solo home run gave the A's the lead at 6-5 in the sixth inning. Chicago answered back with a tying run on Yoan Moncada's RBI groundout in the bottom of the sixth.
Athletics reliever Lou Trivino (5-1) struck out four of the five batters he faced to pick up the win.
Both starting pitchers left the game with injuries. Oakland starter Daniel Mengden suffered a sprained right foot and left after two innings. He surrendered five runs on four hits with a strikeout and a walk.
Chicago starter Dylan Covey left after four innings with a sore hip. He was charged with four runs on two hits, striking out one and walking four.
White Sox reliever Juan Minaya (0-2) took the loss.
Oakland right-hander Paul Blackburn is slated to start in Sunday's series finale. The White Sox are expected to counter with left-hander Carlos Rodon.
