"This was a big one for us," Mariners manager Scott Servais said. "Obviously we know what Texas has done in our division the last two years. We're starting to get some momentum going our way. Wins like that hopefully lead to some bigger things here coming up the next series against Miami."
Nomar Mazara homered off Mariners closer Edwin Diaz in the top of the ninth for a 7-6 lead, but Dyson again couldn't hold a lead for Texas as he blew his third straight save opportunity of the season.
"These guys have been in this spot before," Rangers manager Jeff Banister said.
