SEATTLE (Interstat) — On a night when their offense was held silent for seven innings, the Seattle Mariners authored a stunning comeback to clinch a postseason berth. Josh Naylor laced a bases-clearing, two-out double in the bottom of the eighth inning, erasing a two-run deficit and propelling the Mariners to a dramatic 4-3 victory over the Colorado Rockies on Tuesday night at a raucous T-Mobile Park.

The win, Seattle’s 15th in its last 16 games, improved its record to 88-69 and secured the franchise’s second playoff appearance since 2001. The Mariners entered the game needing a win and a New York Yankees victory over the Chicago White Sox to seal their spot, and both results fell into place. Seattle can now turn its attention to winning the American League West, a goal it can accomplish as soon as Wednesday.

For most of the evening, however, a celebration seemed unlikely. The Mariners managed just three hits and trailed 3-1 heading into the fateful eighth inning against a Rockies team that has endured a dismal season, falling to 43-114.

The game was a stark contrast in pitching styles early on. Colorado starter McCade Brown was dominant, striking out 10 Mariners over five innings of work while allowing just two hits and one run. His counterpart, Seattle’s Bryce Miller, battled through 5 2/3 innings, surrendering three runs on five hits while striking out four.

Colorado struck first in the second inning. Jordan Beck led off with a double down the left-field line, advanced to third on a sacrifice bunt by Ezequiel Tovar, and scored on a two-out, ground-ball single to right field by Kyle Karros.

The Rockies extended their lead in the sixth. Mickey Moniak doubled and, after a walk to Blaine Crim, both runners advanced on a deep flyout. Tovar then delivered a crucial two-run single to right field, scoring Moniak and Crim to give Colorado a 3-0 advantage.

Seattle’s only offense through the first seven innings came via the solo home run. Dominic Canzone led off the bottom of the fifth inning by lining a shot over the right-field fence, his 11th of the year, to cut the deficit to 3-1. Brown, however, limited the damage, stranding a walk later in the inning.

The Mariners’ bullpen kept the game within reach after Miller’s departure. Carlos Vargas, Gabe Speier, and Eduard Bazardo combined for 2 1/3 innings of scoreless relief, allowing just two hits and striking out four. Speier was particularly sharp in the top of the eighth, striking out the side around a single.

That set the stage for the improbable bottom of the eighth against Rockies reliever Juan Mejia. Pinch-hitter Luke Raley was hit by a pitch to start the inning. After J.P. Crawford worked a walk, Mejia struck out Randy Arozarena for the first out. He then fanned Cal Raleigh for the second out, bringing Julio Rodríguez to the plate with the season on the line.

Mejia hit Rodríguez with a pitch, loading the bases for Naylor. On a 1-1 count, Naylor drove a sharp line drive into the gap in left-center field. The ball one-hopped the wall, clearing the bases as all three runners scored easily. Naylor slid into second base with a double, and T-Mobile Park erupted as the Mariners seized a 4-3 lead.

Andrés Muñoz entered in the ninth to close it out for Seattle. He overpowered the heart of Colorado’s order, striking out Ezequiel Tovar and Brenton Doyle before getting Kyle Karros to strike out swinging on a pitch in the dirt, which was scooped by catcher Cal Raleigh and thrown to first for the final out. The save was Muñoz’s 38th of the season.

The victory went to Speier, who improved to 4-3. Mejia took the loss for Colorado, falling to 2-2.

Despite being outhit 7-3, the Mariners capitalized on their limited opportunities, drawing five walks and being hit by three pitches. Colorado’s offense was hampered by hitting into two double plays. The game time was 2 hours and 30 minutes, played in front of an announced crowd of 35,925.

The Mariners will look to build on the momentum and secure the AL West title when the two teams meet again Wednesday. The Rockies, long eliminated from contention, will continue to play the role of spoiler as their difficult season winds down.
