KANSAS CITY — An annoying case of back spasms earlier this week temporarily slowed the runaway offensive train that has become Royals’ infielder Hunter Dozier.

But Dozier was back smashing the ball Saturday night, posting his first two-triple game of his career and his first career four-hit game to go along with a career-high four RBIs in the Royals’ 9-4 win over the Angels.

Dozier, who now is hitting .350, was 10-for-24 on the recent road trip, and didn’t even play the final two games when back spasms forced him to rest. He had three doubles and four home runs on the trip. Dozier now is 15 for his last 33.

During the Royals’ six-run third inning, Dozier shot a two-run triple into the right-field corner.

After the Angels had sneaked within 7-4, Dozier came through with a two-out, two-run triple to left-center in the fifth.
