Arizona right-hander Zac Gallen pitched six scoreless innings, Corbin Carroll doubled and scored, and the Diamondbacks beat the Texas Rangers 2-0 in Phoenix on Wednesday.

Gallen (11-13) stretched his scoreless streak to 12 innings, and he has given up only one run in his last 18 innings over three starts. His ERA dropped to 4.77, the lowest it has been since early May.

Carroll has 73 extra-base hits, tied with the New York Yankees' Aaron Judge for second in the majors. The Los Angeles Dodgers' Shohei Ohtani has 74.

Gabriel Moreno hit an RBI single in the first and the Diamondbacks scored on an infield error in the second in a game defined by pitching. The D-backs had three hits, none after the second inning.

Gallen permitted four hits, only one hit after Ezequiel Duran's two-out double in the second inning. He struck out five and walked one. The Rangers, who had five hits, had as many as two runners on base in only the first and fifth innings.

Texas starter Jack Leiter (9-8) gave up two runs on three hits in six innings, with eight strikeouts and three walks. He retired 13 of the last 14 he faced after Arizona scored in the second. Leiter has a 2.89 ERA in his last 12 starts.

Arizona (70-71) has won six of eight and is 4-0-1 in its past five series. The D-backs are 5 1/2 games behind the New York Mets for the third National League wild-card spot.

The Rangers (72-69) remained 1 1/2 games behind the Seattle Mariners for the final American League wild-card position.

Jake Woodford pitched around a one-out walk in the ninth for his third save in six chances.

The Diamondbacks took a 1-0 lead in the first after Ketel Marte walked with one out. Marte was thrown out at home trying to advance on Carroll's double before Moreno singled in Carroll.

Alek Thomas walked and Tyler Locklear singled with one out in the second, and Thomas scored from third for a 2-0 lead when first baseman Jake Burger mishandled Jake McCarthy's grounder for an error. Burger's error was Texas' first in 20 games.
