Astros take on Giants in Houston Wednesday.

HOUSTON (AP) — Justin Verlander got some run support for the first time in nearly a month and led the Houston Astros over the San Francisco Giants 4-1 on Wednesday.

Verlander (6-2) struck out nine and walked one in six innings, allowing one run and three hits as his major league-leading ERA rose slightly to 1.08. He had given up just three runs over 29 innings during his previous four starts, but the Astros had scored just three runs in that span, getting shut out twice.

Will Harris, Brad Peacock and Ken Giles each followed with a onehit inning. Giles remained perfect in nine save chances.

George Springer hit a tiebreaking, two-run homer in the fifth off Jeff Samardzija (1-3), driving the ball off the facade above the left-field seats. Carlos Correa added an RBI single later in the inning.

Samardzija allowed four runs, four hits and a season-high five walks in 4 2/3 innings.

ROYALS 5, CARDINALS 2, 10 INNINGS

ST. LOUIS (AP) — Drew Butera had a two-run single in the 10th inning and the Royals earned a victory over the Cardinals.

Butera's RBIs were his first since May 2. Jon Jay followed with an RBI single as the Royals won their first series since taking three of four from Detroit May 3-6.

Salvador Perez hammered a first-pitch fastball by Cardinals starter Michael Wacha for his eighth home run of the season to lead off the second.

Blaine Boyer (2-0) pitched a scoreless ninth for the win.
