The Rangers managed four hits in their fifth consecutive defeat overall. They matched the second-longest road skid in team history, an 11-game stretch in April and May 1982. Texas dropped 12 in a row away from home in May and June 2003.
“I think overall a lot of guys are struggling now on offense," Rangers manager Chris Woodward said. “It's unfortunate. I think it gets contagious.”
Crawford hit a solo homer in the seventh inning to break a 1-all tie and Haniger added his 14th of the season in the eighth. The long balls gave the Mariners their season-high third straight victory and their major league-leading 12th one-run win.
Seattle is 12-5 in one-run games, including Friday’s 3-2 victory over Texas.
“That's cool,” Crawford said. “I didn't know that.”
Of his homer, he said: “I was just trying to get a little spark for my team in that inning.”
José Godoy singled home Kyle Lewis in the second for Seattle's first run.
Mariners starter Justin Dunn struck out eight and pitched one-hit ball through 5 2/3 innings to stretch his AL-leading streak of games with three or fewer runs allowed to 15. But he was pulled after allowing his second hit, again failing to make it through the sixth.
“I haven’t pitched a big league game since 2019,” Zamora said after getting four outs. “There was a lot of adrenaline going through me. I think that was part of it all, too.”
Dunn hit Isaiah Kiner-Falefa with a pitch leading off the fourth, then issued back-to-back walks with one out before Solak’s sacrifice fly tied it at 1.
Mike Foltynewicz (1-5) scattered six hits over seven innings, striking out two, but was done in by Crawford’s second homer of the season.
Woodward said Foltynewicz pitched well enough to win in his second straight seven-inning appearance, but the team wasn't “scratching and clawing” for runs.
“There's a few innings where we didn't put any pressure on them,” the manager said.
Mariners: RHP Will Vest returned to the team after his COVID-19-related stay on the injured list.
