Amed Rosario hit two of the Yankees' six home runs as visiting New York beat the Kansas City Royals for a 12th straight regular-season meeting, prevailing 15-1 on Tuesday night.

New York's Cody Bellinger, Anthony Volpe, Trent Grisham and Jazz Chisholm Jr. also went deep. Rosario had four hits and four RBIs, and the homer-hitting quintet combined for 12 RBIs. Grisham, Volpe, Ben Rice and Austin Wells each had three of the Yankees' 24 hits.

It was the first time in Yankees history that all nine starters had at least two hits.

That was more than enough offense for Cam Schlittler, who allowed one run over six strong innings. He yielded only Bobby Witt Jr.'s third-inning homer while lowering his ERA to 1.50. Schlittler (7-2) gave up four hits while striking out six without a walk.

Winners of three straight, New York has not lost to Kansas City since Game 2 of the 2024 American League Division Series. Overall, the Royals have lost 14 of their past 19 games.

Royals opener Bailey Falter (0-2) got the first two Yankees hitters out on two pitches. Bellinger sent the fourth pitch of the game over the right field fence.

Paul Goldschmidt then doubled and scored on a single by Rice that was originally called a catch by Royals right fielder Jac Caglianone, but overturned via a New York challenge. Rosario capped the four-run first with a two-run drive into the left field stands.

The Yankees added a run in the second, when Volpe's drive barely cleared the left-center-field wall. They made it 9-0 with four more runs in the third, two charged to Falter, who exited with one out in the inning. New York got an RBI single to left from Volpe, a run-scoring groundout from Grisham and Bellinger's single that plated a pair.

Falter allowed seven runs on nine hits in 2 1/3 innings. He had no strikeouts and no walks.

Schlittler, meanwhile, was cruising until Witt went the opposite direction, clearing the right field fence with two outs in the third.

Aaron Judge got in on the fun in the fifth with an RBI double. Grisham's solo shot came in the seventh against Steven Cruz. Chisholm became the last Yankees starter with a hit when he went deep during a two-run eighth, and Rosario clubbed a two-run homer off position player Tyler Tolbert in the ninth.
