KANSAS CITY, Mo. (AP) — Jordan Walker homered and Miles Mikolas pitched six sharp innings to lead the surging St. Louis Cardinals past the Kansas City Royals 1-0 on Saturday night.

Mikolas (3-2) allowed two hits with four strikeouts and two walks for the Cardinals, who have won three straight and 12 of 13. St. Louis is 7-1 on a nine-game trip to three cities, winning all three series.

Walker connected leading off sixth. Iván Herrera’s two-out single in the fifth was the only other hit for the Cardinals.

Kyle Leahy permitted two hits in two innings of relief and Ryan Helsley finished the four-hitter for his ninth save.

Hard-luck loser Noah Cameron (1-1) went 6 1/3 innings in his second major league start. The 25-year-old left-hander from St. Joseph, Missouri, became the first pitcher to begin his career with consecutive starts of 6 1/3 or more innings without giving up more than two hits in either one.
