KANSAS CITY, Mo. (AP) — Guardians rookie Steven Kwan kept up an historic start to his big league career with a bases-loaded triple Monday, becoming the first player to reach base at least three times in each of his first four games while leading Cleveland over the Kansas City Royals 10-7.

Kwan, who went 5 for 5 and safely reached six times a day earlier, finished the series 9 for 13, got on base in 15 of 19 plate appearances and scored four times. His three RBIs in the eighth inning Monday were the first of his career.

Oscar Mercado added a two-run homer for the Guardians, who had scored just once over the first two games of the series but piled up 27 runs over the last two to split the season-opening set.

Logan Allen (1-0) earned the win with two scoreless innings of relief in his first appearance of the season.

The series finale was tied 4-all in the seventh when Royals reliever Jake Brentz (0-1) gave up a single, sacrifice bunt and walk. Josh Staumont then gave up bloop singles to Jose Ramirez and Franmil Reyes as Cleveland took a 6-4 lead.

The Royals loaded the bases in the bottom half against Bryan Shaw before Hunter Dozier hit a flyball that Kwan dropped in left field. As a run crossed the plate, Kwan threw out the runner at second base in a bang-bang play that stood upon video review. Nick Sandlin relieved and got Adalberto Mondesi to ground into an inning-ending double play.

Then, the Guardians watched the 24-year-old Kwan cap his dazzling debut series with his three-run triple in the eighth.

Mercado also had a big finish to the series. He hit a grand slam and had five RBIs in the Guardians’ 17-3 romp Sunday, then drilled a two-run homer into the left-field bullpen to give Cleveland a 4-1 lead in the fourth on Monday.

The Royals answered his latest shot in their typical fashion: They scratched and clawed and scrapped for runs. It took two singles, a walk, a sacrifice bunt, a stolen base, an error and a run-scoring groundout, but the Royals managed to coax three runs in the fourth inning to even the score 4-all.

Only one of the four runs off Cleveland starter Aaron Civale was earned, and he left after 3 1/3 innings. Carlos Hernandez lasted another inning for Kansas City but was responsible for all four runs that he allowed.
