In a season littered with forgettable games and unsuccessful stretches, remember Wednesday.

Not only were the White Sox trailing the Mariners 4-0 in Michael Kopech's return to the mound, Seattle starting pitcher Luis Castillo looked to have no-hit stuff after striking out the first seven hitters he faced.

"I thought it was going to be a long day," acting Sox manager Miguel Cairo told reporters. "But you know, the guys fought back and it was a team win and it was unbelievable."

In a back-and-forth affair against a Mariners team that had won 10 of its last 12 to solidify a wild-card berth, the White Sox got up off the mat and exited T-Mobile Park with a 9-6 win.

The Sox took 2 of 3 from Seattle before heading to Oakland for a four-game series against an Athletics team that has the worst record (50-87) in the American League.

"He's a pretty good pitcher," Eloy Jimenez said of Castillo, who the Mariners acquired from the Reds in a July 30 trade that sent three of their top prospects to Cincinnati. "He started really good. But we never give up."

Jimenez got the rousing comeback going with a 2-run homer off Castillo in the fourth inning, but it was Jose Abreu providing the spark.

On a team that's had issues running hard to first base, Abreu grounded to third and busted it down the line to avoid a double play. Jimenez followed with a 423-foot home run.

"If I was still playing right now, I'd want to be like (Abreu)," Cairo said. "I will follow him. I would be imitating the way he works, the way he prepares himself. He's the captain, he's the horse."

Abreu (RBI single) and Jimenez (RBI double) struck again in the sixth inning, when the Sox scored 4 runs to take a 6-4 lead.

The Mariners answered back with solo runs in the sixth and seventh to tie the game before the White Sox took a 7-6 lead in the eighth inning and tacked on 2 more runs in the ninth.

"These were the games earlier in the year we weren't able to pull out," said Sox closer Liam Hendriks, who struck out the side in the ninth inning to earn his 31st save. "That's one thing we've got going in this clubhouse right now, we're not backing down. We're not afraid to claw our way back and do that sort of stuff. It was a good team effort."

Making his first start since facing only four batters in an Aug. 22 games against the Royals and exiting with a left knee strain, Kopech pitched 3⅔ innings against Seattle and gave up 4 runs on 4 hits and 2 walks to go with 4 strikeouts.

"Physically, I felt great," Kopech said. "Ball was coming out good, knees felt good, shoulder felt good. I'm glad I'm back, glad I can make a contribution to the team. Wish I had done a little better job but either way, we came out with a W."
