LOS ANGELES (AP) - Lucas Harrell took a shutout into the eighth inning, J.D. Martinez homered and the Houston Astros used four relievers in the eighth to get out of a bases-loaded jam and help secure a 3-1 victory over the Los Angeles Dodgers on Friday night.

Harrell (4-3) scattered five singles, walked three and did not strike out a batter during the longest of his 15 big league starts. The 26-year-old right-hander, facing the Dodgers for the first time, allowed only two runners as far as second base and got 17 of his outs on groundballs - including all three outs on comebackers to the mound in the seventh inning.

Clayton Kershaw (4-2) was charged with three runs - two earned - and five hits over seven innings with six strikeouts on the fourth anniversary of his major league debut.
