Drew Waters, MJ Melendez and Michael Massey each hit two-run home runs and the Kansas City Royals snapped a three-game losing streak with a 9-3 win over the Boston Red Sox on Tuesday night.

Brady Singer (8-8) allowed three runs off five hits over 6 2/3 innings, and the Royals finished with six extra-base hits and six stolen bases

Adam Duvall had his 10th home run of the season, and Connor Wong and Jarren Duran added RBIs for Boston, which has lost five of its last six.

Waters said the Royals’ 15-hit night was a result of recent dedication in the cage finally paying off.

Kutter Crawford (5-6) allowed three runs on seven hits over 3 1/3 innings, striking out six and walking two.

With Kansas City leading 1-0 with a runner on in the fourth, Waters connected on Crawford’s cutter and lofted it into Boston’s bullpen in right field for his seventh homer of the season.

Three batters later, Crawford let a fastball get too far inside on Bobby Witt Jr., striking him on his hand. Witt was attended to by a trainer but stayed in the game.

It was the final batter for Crawford. He was replaced by Brennan Bernardino, who was able to get out of the inning without any further damage.

The Red Sox cut the lead to 3-1 in the fifth when Duvall drove Singer’s sinker over the Green Monster seats in left field.

Later, Wong trimmed the gap to 3-2 with a single that scored Alex Verdugo.

The rally was short-lived.

Maikel Garcia led off the sixth with a walk against Red Sox reliever Dinesel Lamet, stole second, then advanced to third on a wild pitch. Garcia scored two batters later via Massey’s groundout.

Salvador Perez singled and Melendez followed with his 10th homer of the season to stretch the lead back to 6-2.
