KANSAS CITY, Mo. — The pitching matchup between left-handed aces Tarik Skubal and Cole Ragans didn't disappoint, but the Detroit Tigers were a disappointment for the third game in a row against the Kansas City Royals.

The Tigers lost, 8-3, on Wednesday.

Maybe this team isn't a postseason contender after all.

The Tigers (23-26) — now on a four-game losing streak — were swept by the Royals in three games at Kauffman Stadium, falling to 9½ games behind the first-place Cleveland Guardians in the American League Central. Since their 5-0 start, the Tigers have an 18-26 record in their past 44 games.

In Wednesday's series finale, Ragans beat Skubal in the anticipated matchup between heavyweight southpaws.

Ragans fired six scoreless innings on one hit and three walks with 12 strikeouts, throwing 100 pitches; Skubal surrendered four runs on six hits and two walks with six strikeouts in five innings, throwing 96 pitches.

Ragans registered a career-high 12 strikeouts.

The Tigers didn't get a hit against Ragans until Riley Greene slapped a two-strike fastball into left field for a single with two outs in the sixth inning. Before that, Ragans walked Jake Rogers in the third inning, Matt Vierling in the fourth inning and Vierling again in the sixth.

After Greene's single, Ragans responded by striking out Gio Urshela to strand two runners in the sixth and compete his outing. Eight of the nine batters in the Tigers' starting lineup struck out against Ragans, with Greene as the exception.

Ragans generated 10 of 15 whiffs with his fastball, which averaged 95.3 mph. He also picked up four whiffs with his changeup. The 26-year-old dropped his ERA from 3.70 to 3.34 with a brilliant performance in his 11th start this season.

Tarik Skubal

Skubal kept the Royals to four runs, but he wasn't at his best.

The Royals scored their first two runs in the second inning, when Freddy Fermin hit an RBI double on Skubal's middle-middle fastball and Garrett Hampson hit an RBI double on Skubal's middle-down changeup.

Both doubles occurred in full counts.

In the fourth inning, Nelson Velázquez demolished Skubal's middle-in sinker that caught too much of the middle of the plate for a solo home run. He hit the ball 430 feet to left-center field with a 110.2 mph exit velocity.

It was the fourth homer allowed by Skubal in 60 innings this season, matching the same number of homers he gave up in 80⅓ innings last season.

The Royals took a 4-0 lead on three singles in a row from Maikel Garcia (changeup), Bobby Witt Jr. (changeup) and Vinnie Pasquantino (fastball) in the fifth inning. Skubal finished his outing by getting Salvador Perez to ground into a double play.

Skubal threw 31 four-seam fastballs, 21 changeups, 20 sliders, 20 sinkers and four curveballs. He threw just 21.9% changeups, down from his season average of 27.9%.

The 27-year-old generated 14 whiffs on 50 swings — a worse-than-normal 28% whiff rate — with seven fastballs, three changeups and four sliders. His fastball still averaged 96.6 mph, but his changeup was not sharp for the first time in a long time.

His ERA jumped from 1.80 to 2.25 ERA in his 10th start.

A few runs not enough

The Tigers scored two runs in the seventh inning against left-handed reliever Will Smith, who replaced Ragans. Spencer Torkelson grounded out and Javier Báez popped out, but Colt Keith walked, Jake Rogers singled and Andy Ibáñez delivered the big hit.

Ibáñez hit a fastball for a two-run double to base of the wall in left-center field.

The Tigers cut their deficit to 4-2.

For matchup reasons, Kerry Carpenter — a left-handed hitter — came off the bench as a pinch-hitter for the right-handed Vierling when the Royals called right-handed reliever John Schreiber out of the bullpen to replace Smith.

Schreiber walked Carpenter on eight pitches, bringing the game-tying run to the plate in Mark Canha, but Canha — who finished 0-for-4 with three strikeouts — flew out to right field and stranded the runners in the top of the seventh inning.

The Royals got the runs back (and then some) in the bottom of the seventh inning, when Bobby Witt Jr. delivered a two-run double off right-handed reliever Alex Lange's two-strike curveball below the strike zone. Lange threw five pitches to Witt, and all of them were curveballs.

The double from Witt extended the Royals' lead to 6-2. Fermin boosted the margin to 8-2 with a two-run single off Lange's first-pitch sinker with two outs in the seventh inning. Lange, who has a putrid 18.9% walk rate, owns a 4.34 ERA after giving up four runs.

Javier Báez made it 8-3 with an RBI single off left-handed reliever Angel Zerpa in the eighth inning.
