KANSAS CITY, Mo. (AP) — Bobby Witt Jr. and Salvador Perez hit two of Kansas City’s four home runs to back a strong start by rookie Noah Cameron, and the Royals beat the Pittsburgh Pirates 9-3 on Monday night. Cameron struck out seven in a season-high seven innings. The left-hander allowed three hits, a walk, and two runs — on Tommy Pham’s two-run shot in the third. Witt went 2 for 3 and scored twice to extend his hitting streak to 11 games. Witt hit his 13th homer, a two-run shot the opposite way to right-center field off reliever Chase Shugart to give the Royals a 6-2 lead in the fourth.
