CHICAGO — Todd Frazier’s first season in Chicago has produced 31 home runs, but also an average hovering around .200 and 125 strikeouts.

On Thursday night, Frazier provided the clutch hitting the White Sox coveted when they traded for him in the offseason.

After striking out in his first three at-bats, Frazier tied it with an RBI single in the seventh inning and won it with a liner down the left-field line in the ninth to lift the White Sox to a 7-6 victory over the Seattle Mariners.

“You can’t rely just on the homer,” Chicago manager Robin Ventura said. “I think there’s more to his game than that. You’ve got to be able to knock in runs when you’re not hitting them over the fence.”

Adam Eaton hit a bloop single off Nick Vincent (3-4) to open the ninth and went to second on Tim Anderson’s sacrifice. Jose Abreu was walked intentionally before Frazier’s liner over third scored Eaton, leading to a pileup of players behind the pitcher’s mound.

“Unfortunately, it took me three times to do that,” Frazier said. “To come up clutch today, I felt pretty good.”

David Robertson (4-2) worked around a walk and two incidents of fans running on the field in the ninth that delayed play for several minutes in Chicago’s fourth win in five games.

“The first two guys I was like, ‘Ok. All right. They’ve got it under control,'” Robertson said. “The next guy, I got a little angry there.”

Robinson Cano hit his 29th home run and the Mariners wasted a solid return off the disabled list by James Paxton in their third straight loss. Seattle fell 7 1/2 games behind AL West-leading Texas.

Leonys Martin had a two-run single in a three-run sixth as Seattle built a 6-3 lead off White Sox starter Anthony Ranaudo.

But Anderson, who had three hits, led a seventh-inning rally with an RBI double off struggling Arquimedes Caminero before Frazier’s two-out ground single off Steve Cishek tied it.

Paxton gave up five singles and three runs in the first, then scattered two hits in four scoreless innings before leaving after 90 pitches in his first start since getting hit on the elbow by a comebacker Aug. 7.

“It was just a little bit of rust,” Paxton said. “I was missing the middle a little bit and they were finding some holes. As it went al png made some better pitches.”

Ketel Marte’s fielding error on J.B. Shuck’s leadoff grounder in the seventh led to three unearned runs for Chicago.

Ranaudo was charged with six runs and five hits in 5 1/3 innings in his third third start with the White Sox.

“Against a lineup like that, your mistakes get exposed,” Ranaudo said. “I think that happened, but luckily we’ve got a good team and we’re having some fun right now.”

TRAINER’S ROOM

Mariners: 3B Kyle Seager (bruised right foot) missed his second straight game, with manager Scott Servais saying it’s “50-50” if he’ll play Friday. Mike Freeman was recalled from Triple-A Tacoma for infield depth, with RHP Tony Zych sent down. … DH Nelson Cruz hit a sacrifice fly in the first a day after leaving with back spasms.

White Sox: LF Melky Cabrera (illness) sat out. … GM Rick Hahn said CF Austin Jackson (knee surgery) and INF Matt Davidson (broken foot) won’t return this season. … An MRI on 2B Brett Lawrie, out with hamstring, calf and knee issues, came back clean.

UNRULINESS

Two men initially ran on the field, with one removing his shirt. One was tackled on the field, while another jumped back into the stands before he was taken by security. Then before a pitch was thrown, another man ran on the field and also took off his shirt.

Robertson treated it like a replay challenge delay.

“Seemed like getting the guys off the field, at least it was something to watch instead of just watching the umpires holding the headphones and just listening,” he said.

STARTING OVER?

White Sox chairman Jerry Reinsdorf hasn’t authorized rebuilds in the past. But with Chicago on pace for a fourth straight losing season, Hahn reiterated a roster teardown is possible.

“Everyone in that front office is looking for the best path to get us on an extended period of success,” Hahn said, “even if that involves a short-term step back.”
