CHICAGO — Tarik Skubal wasn't at his best.

Skubal, the ace of the Detroit Tigers, remains the frontrunner to win the American League Cy Young Award, but the steady left-hander stumbled for the first time in a long time Saturday night against the lowly Chicago White Sox.

He allowed three runs in five innings, throwing 88 pitches.

The Tigers, though, supported Skubal by scoring eight runs between the third and fourth innings, which led to what ended up a blowout 13-4 win over the White Sox in the second of four games in the series at Guaranteed Rate Field.

Skubal has an MLB-leading 2.58 ERA in 26 starts.

The Tigers (64-66) can reach .500 for the first time since June 5 with back-to-back wins Sunday and Monday to conclude the four-game series, thus sweeping the White Sox, who dropped to 31-99.

In Saturday's game, Skubal gave up eight hits — only the second time he has allowed more than seven hits this season — with zero walks and eight strikeouts. Five of the eight hits came in the 26-pitch third inning, with four of them in a row.

The White Sox opened the third with four consecutive hits: Dominic Fletcher ripped a double to right field on a down-and-in slider, Brooks Baldwin flared a single to center field on a fastball at the bottom of the strike zone, Corey Julks smacked a single to right field on an inside sinker, and Luis Robert Jr. pulled a single to left field on middle-middle changeup that should've been below the zone.

The hits from Fletcher and Julks were with two strikes, while Robert jumped a poorly located first-pitch changeup. One run scored on each of the singles from Julks and Robert, cutting the Tigers' lead to 5-2.

The White Sox scored their third run, making it 5-3, with one out in the third inning, when Andrew Vaughn redirected an up-and-in sinker for a hard-hit single into center field. One pitch before the single, Vaughn missed a home run opportunity by fouling off a middle-middle changeup.

After Vaughn's single, Skubal retired eight of the final nine batters he faced to complete his rocky start. Three of the eight hits off him belonged to Julks, who also had a leadoff single in the first inning.

Skubal generated 11 whiffs on a 49 swings — a 22.4% whiff rate — with four fastballs, five changeups and two sliders. His fastball averaged 95.6 mph, down 1.3 mph from his season average.

Supporting Skubal

The Tigers ran circles around left-hander Ky Bush and right-handed reliever Touki Toussaint in the third and fourth innings, occurring immediately before and after Skubal surrendered three runs.

The breakthroughs created longer-than-usual wait times for Skubal. The four-run third kept him on the bench for nearly 19 minutes; the four-run fourth kept him on the bench for more than 23 minutes.

SERIES OPENER: Tigers surge late for 5-2 win over Chicago White Sox

The Tigers grabbed a 1-0 lead in the first inning on Andy Ibáñez's RBI single, then separated themselves from the White Sox in the third and fourth innings.

For a 2-0 lead, Matt Vierling turned on a middle-in fastball from Bush for a leadoff solo home run to left-center field in the third inning, his 15th homer of the season. Colt Keith's groundout, Jake Rogers' double and Parker Meadows' single also drove in runs, extending the margin to 5-0.

Facing Toussaint, the Tigers walked three times in a row — Ryan Kreidler, Vierling and Jace Jung — to start the fourth inning, in which runs scored on Riley Greene's force out and Spencer Torkelson's single for a 7-3 lead. A two-out single from Rogers made it 9-3.

Late-game runs

The White Sox scored their fourth and final run in the seventh inning off right-handed reliever Brenan Hanifee. In the top of the ninth, Keith crushed a two-run home run — his 12th of the season — for an 11-4 advantage.

It was Keith's first homer since July 27.

Zach McKinstry also tacked on a two-run home run in the ninth for a 13-4 lead. Both Keith and McKinstry hit home runs off right-handed reliever John Brebbia.

Vierling, Keith, Rogers Meadows and McKinstry produced multi-hit games in the Tigers' 14-hit performance, which also included five walks. Every starter except Ryan Kreidler collected a hit.
