CHICAGO -- Chris Sale watched from the dugout as teammate Adam Dunn just missed a game-winning home run in the 10th inning Thursday, and he had a good view of Conor Gillaspie being robbed of a tying homer by Josh Reddick in the ninth a night later.
He'd rather have not seen it at all.
Josh Donaldson hit his first career grand slam, Reddick made a homer-saving catch in the ninth inning, and the Oakland Athletics rallied from a three-run deficit for a 4-3 victory over Sale and the Chicago White Sox.
"I know we are not playing like how we want to play or how we should play, pitching, defense, hitting and all that stuff but we're just running into some tough breaks, running into some bad luck," Sale said. "Robbing a home run? That's when you know it's not going your way at all."
Donaldson's ninth home run of the season came in the sixth inning and helped Oakland right-hander Jarrod Parker (5-6) earn his fourth win in five decisions.
Reddick made a leaping catch to take away a home run from Gillaspie with one out in the ninth to preserve the win.
The White Sox lost for the 10th time in 11.
Sale (5-4) hadn't given up more than two earned runs since April 13 at Cleveland, and he cruised out to a 3-0 lead through five innings in this one.
In the sixth Adam Rosales singled and, after Coco Crisp struck out, Jed Lowrie singled. Yoenis Cespedes followed with walk, and Donaldson hit a 1-1 pitch for an opposite-field home run to right to give Oakland a 4-3 lead.
"They battled him hard that inning. Obviously, that is the only bad inning he had. As far as I'm concerned that game in Cleveland he had another inning like that, so basically he's had only two bad innings all year," said interim manager Don Cooper.
Sale was surprised the ball carried out on the cool night.
"Off the bat, I figured it was going to be a sac fly or something, it just kept going," said Sale. "Just shows you how important one pitch can be in a ballgame."
The Athletics won for the 18th time in 21 games.
"That's big time stuff. We've scored five runs off this guy (Sale) in two games and beat him twice and Donaldson has knocked in all five runs, said Oakland manager Bob Melvin. "He keeps coming up with bigger and bigger hits and his approach is great every time especially with runners in scoring position. He's pretty impressive."
Parker beat the White Sox for the second time in five days with a seven-inning, five-hit effort. He walked two and struck out four.
"It's a fun run. I think right now we're putting together complete games and we're playing well in all facets of the game," Parker said. "Obviously as a starting staff we know it's whatever we can do to keep us in the game. For us just to hang around tonight was huge."
Reliever Ryan Cook pitched out of a first-and-second jam with none out in the eighth and Grant Balfour pitched the ninth for his 15th save.
Sale stayed in the game for 118 pitches. He left after striking out Crisp to lead off the eighth. Sale allowed five hits, walked one and struck out six.
The White Sox had runners on first and second with no outs in the eighth, but Alexei Ramirez killed the momentum when he popped out on a bunt attempt.
"We got to fight about getting discouraged when it happens. We got our best guy out there. Things are looking good all of sudden they aren't looking so good," said Cooper. "But we did battle back. Again, not getting a bunt down that don't help, giving team an out there,"
The White Sox led 1-0 on Tyler Flowers' third-inning home run on a 0-2 pitch by Parker.
In the fourth, Dayan Viciedo's sacrifice fly to left scored Alex Rios, who had singled, stole second when Dunn struck out, and moved to third when catcher Derek Norris threw the ball into center field for an error on the stolen base.
Chicago expanded the lead to 3-0 on a fifth-inning sacrifice fly by Alejandro De Aza, scoring Gordon Beckham. Beckham had led off with a single, moved up on Jordan Danks' ground out and took third on Flowers' single.
