articleThe Brief Victor Robles' diving catch in right field in the ninth inning on a looper liner from Carlos Correa led to a game-ending double play that allowed the Mariners to hold on for a 6-4 victory over the Astros. Eduard Bazardo, Gabe Speier and Andrés Muñoz pitched two scoreless innings to close out the win, with an assist from Robles in the ninth. With the victory, the Mariners clinched the season-long tiebreaker over the Astros, which effectively gives Seattle a three-game lead in the AL West with seven games left to play – including Sunday's series finale in Houston. George Kirby (10-7) scattered five hits across six scoreless innings and struck out seven to help the Mariners to the victory that assures them a season series win over the Astros. Seattle led by 6 with two outs in the seventh when Peña’s grand slam off Carlos Vargas got the Astros within 6-4.
