SCOTTSDALE, Ariz. -- Jake Peavy pitched four innings, allowing a three-run home run to Texas' top prospect Joey Gallo, and the Rangers beat the San Francisco Giants 3-0 on Friday.
Nick Martinez, in the mix for a spot in the starting rotation, allowed two hits over 2 2-3 innings. He struck out four without walking a batter.
Ross Detwiler, also a candidate for a starting spot, pitched two scoreless innings, allowing two hits, walking one and striking out two.
Peavy, who hit two batters, got in trouble in the third after hitting Hanser Alberto leading off. Delino DeShields, who left the game with tightness in his right hamstring, followed with a bunt single.
One out later, Gallo drilled Peavy's first pitch over the right field fence for his second homer of the spring.
Joe Panik doubled and Buster Posey singled with two outs in the first, the closest the Giants came to scoring.
Brandon Belt tripled in the sixth but was thrown trying to score on a wild pitch.
