HOUSTON - Derek Fisher homered and had an RBI single for his first major league hits in a nine-run sixth inning to help the Houston Astros to a 13-2 victory over the Texas Rangers on Wednesday night to avoid a three-game sweep.
The Astros led by three with no outs in the sixth when Fisher, who made his debut on Wednesday, connected off Jeremy Jeffress for a solo home run to the seats in left field. Two pitches later, Jake Marisnick hit a pitch into nearly the same spot to extend the lead to 6-1.
Houston had pushed the lead to 10-1 when Fisher came up again with two outs in the inning. This time he laced a single to right field to send another run home.
But the Astros weren't done scoring in that inning yet. Dillon Gee plunked Marisnick before George Springer added a two-run double to make it 13-1. The Rangers finally escaped the sixth when the 13th batter of the inning, pinch-hitter Alex Bregman, grounded out.
Houston's top prospect Francis Martes (1-0) allowed three hits and one run while fanning seven in five innings in his first major league start.
Rangers starter Andrew Cashner (3-6) yielded 10 hits and four runs in 4-plus innings for the loss.
Joey Gallo hit his 18th home run on a 466-foot shot to straightaway center field in the seventh for the Rangers, whose five-game winning streak was snapped.
Marwin Gonzalez drove in three runs and Brian McCann and Carlos Beltran added two RBIs apiece for the Astros.
Houston took a 1-0 lead on a groundout by Carlos Correa in the first. McCann doubled to start the second and the Astros extended their lead to 2-0 when he scored on a single by Gonzalez.
Martes sailed through the first four innings, retiring 12 of the first 14 batters he faced. He ran into trouble in the fifth when Jonathan Lucroy started the inning with a single. Martes then walked Gallo before plunking Jurickson Profar.
Martes struck out Jared Hoying before Lucroy scored on a wild pitch to cut the lead to 2-1. Delino DeShields drew a walk to load the bases again, but Martes retired the next two batters to escape the jam.
