KANSAS CITY, Mo. (AP) — Bobby Witt Jr.'s grand slam in the 10th inning gave the Kansas City Royals an 8-5 victory over the Minnesota Twins on Friday night.

Witt finished 4 for 5 with six RBIs, falling a triple short of the cycle and pulling out the game for the Royals after they blew a 4-2 lead in the ninth.

Brady Singer struck out a season-high 10 in five innings for the Royals, who needed their 13th comeback win of the season after Jorge Polanco's two-run double with two outs in the ninth tied it at 4-all.

Minnesota then went ahead on Kyle Farmer's RBI single in the 10th off Taylor Clarke (2-4) before Witt won it with his 17th homer of the season off Jhoan Duran (2-5).

Kyle Isbel hit a leadoff 400-foot home run off Twins starter Sonny Gray in the third. It was the first homer allowed by Gray against the Royals since August 2014.

Witt also had an RBI double in the sixth and a run-scoring single in the eighth.

Gray pitched six innings and gave up three runs on five hits with five strikeouts. Gray extended a 15-game winless streak dating back to April 30 against Kansas City.
