The Seattle Mariners walked off the Arizona Diamondbacks, 3-2, when Victor Robles delivered a run-scoring single in the bottom of the 10th inning, the first walk-off hit of his 10-year major league career. What began as a tightly contested game through nine innings unfolded into extra baseball, and a handful of pivotal moments — two solo homers surrendered by Merrill Kelly, a wild pitch that produced a run for Arizona and a sac fly that tied the game — decided the outcome.
Seattle jumped in front early when Cole Young connected for a solo home run in the bottom of the second inning off Merrill Kelly. The blast put the Mariners on the scoreboard and gave them an early advantage. Young later added a defensive highlight in the top of the eighth with an outstanding jumping grab on a ball hit by Geraldo Perdomo, showing the two-way impact he had on the contest.
Arizona evened matters in the top of the sixth when Corbin Carroll raced home on a wild pitch thrown by Luis Castillo. Nolan Arenado was at the plate when the pitch got away, and Carroll's run made it 1-1. The run erased Seattle's early lead and set the stage for more back-and-forth action in the middle innings.
Seattle reclaimed the lead in the bottom of the sixth when Dominic Canzone homered off Merrill Kelly, a solo shot that pushed the Mariners back in front, 2-1. Kelly, who had given up Young's second-inning home run, surrendered another long ball in the sixth that proved consequential. Later in that same inning, on a play stemming from Julio Rodríguez's at-bat, Ryan Waldschmidt threw out Jhonny Pereda at the plate, a defensive stop that prevented Arizona from tying the score immediately after Canzone's homer.
Arizona answered again in the top of the eighth. Ketel Marte delivered a sacrifice fly to bring in a run off Luis Castillo and knot the game at 2-2. That sac fly erased Seattle's one-run lead and sent the contest into the late innings tied, where both bullpens took over and held the score through the ninth.
In the 10th, Castillo worked his way out of a jam, retiring Ketel Marte to end the threat and keep the Diamondbacks from taking the lead in the top half. On the Seattle side, Jonathan Loáisiga was on the mound in the bottom of the 10th when Victor Robles delivered a single that brought home the winning run. The blow not only ended the game but marked a personal milestone for Robles: it was the first walk-off hit of his decade-long major league career.
The loss extended Arizona's skid to three consecutive games after a stretch in which the Diamondbacks had won 11 of 13. Mariners starter and reliever lines were front and center in the decision, with Merrill Kelly absorbing the two solo homers and Luis Castillo both issuing the wild pitch that produced Arizona's run and later escaping a late-inning jam. Jonathan Loáisiga took the defeat when Robles' single ended the game in the 10th. The sequence of homers, defensive plays and late-inning pitching duels defined a tight game that ultimately finished with Seattle on top, 3-2.
