BOSTON — 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.
Bradley Jr. had two RBI doubles and a single for the Red Sox, who went 6-4 on a 10-game homestand — all under interim manager Torey Lovullo, who took over for John Farrell on Aug. 14. Farrell took a medical leave for the rest of the season to deal with Stage 1 Lymphoma.
Boston trailed 4-2, but scored twice in both the sixth and seventh.
Ryan Hanigan opened the seventh with a single against starter Edinson Volquez and Bradley Jr. hit a grounder inside the first-base bag. He scored on Pablo Sandoval's infield hit off on a dribbler in front of the plate.
Boston had tied it at 4 when David Ortiz had a sacrifice fly and Rusney Castillo an RBI single.
Volquez gave up six runs in 6 2-3 innings.
Trailing 2-1 in the fourth, the Royals scored twice, taking advantage of two errors on one play. Second baseman Josh Rutledge booted a grounder and center fielder Mookie Betts' throw bounced into the Royals' dugout for the first run. Moustakas followed with his RBI double. He homered into the Green Monster seats.
Boston starter Eduardo Rodriguez allowed four runs — two earned — in six innings.
