KANSAS CITY, Mo. (AP) — Seattle rookie Jarred Kelenic spoiled the major league debut of pitcher Jonathan Heasley by hitting a pair of two-run homers that sent the Mariners over the Kansas City Royals 6-2 Friday night.

Kelenic’s first multihomer game of his career kept the Mariners 3 1/2 games behind the New York Yankees for the second AL wild-card spot. Toronto and Oakland also are in the mix.

Chris Flexen (12-6) allowed one run and six hits in 5 2/3 innings.

Heasley (0-1) gave up four runs, all on Kelenic’s homers, and six hits in four innings.

When Heasley delivered his first pitch, he became the fifth Royals pitcher selected in the 2018 draft to pitch for the big league club. According to the Elias Sports Bureau, the 2021 Royals are the first team in MLB history to have five pitchers from the same draft class start a game in one season.

Royals slugger Salvador Perez went 0 for 4 with a walk. He leads the majors with 112 RBIs and has hit 45 home runs — Toronto’s Vladimir Guerrero Jr. hit his 46th earlier in the day.

Heasley gave up a leadoff single to Ty France in the second and Kelenic homered with one out.

In the fourth, Kelenic hit his 12th home run, a 435-foot drive to center field after Heasley hit France with a pitch.

The Royals scored off Flexen in the sixth on Andrew Benintendi’s single. Kansas City eventually loaded the bases, but Michael A. Taylor took a called third strike to end the threat.

Hunter Dozier homered in the Royals seventh.
