Mike Moustakas’ two-run double capped a four-run ninth inning that carried the AL Central-leading Kansas City Royals to an 8-6 comeback victory over the Boston Red Sox on Sunday.

Moustakas also had a solo homer and RBI double for Kansas City, which salvaged a split of the four-game series.

Boston led 6-4 going into the ninth. After left fielder Jackie Bradley Jr. threw out Omar Infante trying for an inside-the-park homer for the first out, Kansas City rallied with four hits against Junichi Tazawa (2-6), tying it on Eric Hosmer’s two-run single. Moustakas hit a bases-loaded double to right.

Chris Young (9-6) retired one batter and Wade Davis got the final three outs for his 11th save.
