HOUSTON (AP) — Martín Maldonado hit a three-run home run to back a strong start by Zack Greinke and help the Houston Astros to a 5-1 win over the San Francisco Giants on Wednesday night.

The game was tied with no outs in the sixth when Carlos Correa, Kyle Tucker and Abraham Toro hit consecutive singles. Houston took a 2-1 lead when Correa scored on a wild pitch by Caleb Baragar (2-1).

Maldonado then knocked his two-strike homer into the seats in left field to make it 5-1.

Greinke (1-0) allowed one run and scattered seven hits over a season-high 6 1/3 innings for his first win. He struck out seven and walked one.

A night after squandering a four-run lead in a 7-6 loss in 10 innings, Houston’s bullpen came through on Wednesday. Brooks Raley struck out two in 1 2/3 scoreless innings after taking over for Greinke, and Blake Taylor pitched a perfect ninth to secure the victory.

San Francisco starter Trevor Cahill, who was selected to the Major League roster before the game, walked four in 1 2/3 innings. Cahill hadn’t played this season while dealing with a fingernail injury. He was only expected to throw about 50 pitches and was pulled after 55.

Mike Yastrzemski tripled on the second pitch of the game and the Giants took a 1-0 lead when he scored on a single by Alex Dickerson.

Houston had just one hit when Myles Straw singled with no outs in the fifth. But he was quickly erased when he was caught trying to steal second base.

Dereck Rodríguez then walked George Springer and Josh Reddick before an RBI single by Alex Bregman on a liner to center field tied it at 1-1.

TRAINER’S ROOM

Giants: INF Donovan Solano missed his second straight game because of abodominal soreness. Manager Gabe Kapler hopes Solano can return for San Francisco’s next game on Friday. Solano is batting .458 with a home run and 15 RBIs. ... OF Austin Slater was scratched from the lineup on Wednesday, but no reason was given for taking him out.

Astros: DH Yordan Alvarez, last season’s AL Rookie of the Year, could make his season debut soon. Alvarez, who has been on the injured list all season for an undisclosed reason, has been working out at the team’s alternate training site in Corpus Christi, Texas, and manager Dusty Baker said he could join the team in the next few days.

UP NEXT

Giants: San Francisco is off on Thursday before Johnny Cueto (1-0, 5.40) is scheduled to start on Friday night in the first of three games against Oakland.

Astros: Houston also has a day off Thursday before opening a three-game series against Seattle. The Astros haven’t announced their rotation for that series.
