SEATTLE (Interstat) — On a night when Luis Castillo was nearly untouchable and Cal Raleigh made history, the Seattle Mariners methodically dismantled the Colorado Rockies 9-2 on Wednesday at a sold-out T-Mobile Park.

Castillo delivered a dominant performance, striking out 10 over 7 1/3 innings of one-hit ball, and Raleigh launched two home runs, including his 60th of the season, to power the Mariners to their fifth consecutive victory before a crowd of 42,883.

The game was effectively decided in the first two innings as the Mariners’ offense erupted against Rockies starter Tanner Gordon. Seattle’s power surge started immediately in the bottom of the first. After Randy Arozarena struck out, Raleigh connected on a solo shot to right field. The very next batter, Julio Rodríguez, followed suit with a homer to left field, marking back-to-back jacks and staking Castillo to an early lead. Josh Naylor then flew out, but Jorge Polanco continued the onslaught with a line-drive homer to right, capping a three-homer inning and giving Seattle a 3-0 advantage.

The Mariners kept the pressure on in the second inning. Dominic Canzone led off with a double and Victor Robles was hit by a pitch. After two outs, Raleigh stepped up again, this time delivering a two-run double to right field that scored both runners and extended the lead to 5-0.

Gordon, the losing pitcher, lasted just 1 2/3 innings, surrendering five runs on six hits. His season record fell to 6-8.

The Rockies, who managed only two hits all night, broke up Castillo’s shutout bid in the fourth inning. With two outs, Blaine Crim hit a solo home run to center field, accounting for Colorado’s first hit and run, making the score 5-1.

Seattle responded immediately in the bottom of the fourth, capitalizing on a Colorado error. Robles reached on a throwing error by second baseman Orlando Arcia and advanced to third on a single by J.P. Crawford. Robles then scored on a sacrifice fly by Arozarena. After a fly out by Raleigh, Rodríguez walked, and Naylor singled to center, scoring Crawford to push the Mariners’ lead to 7-1.

From there, Castillo was in complete control. The right-hander retired 12 of the next 13 batters he faced, with the only baserunner reaching on an error. He mixed a devastating changeup with a high-velocity fastball to keep the Rockies’ hitters off balance all evening. Castillo improved to 11-8 with the victory, departing to a standing ovation after recording the first out in the eighth inning.

The Mariners added insurance runs late. Eugenio Suárez hit a solo home run, his 48th, in the seventh inning. Then, in the eighth, Raleigh provided the final exclamation point, crushing his second homer of the game and his 60th of the year deep to right field. The milestone blast made him just the third catcher in major league history to reach the 60-home run plateau in a single season.

Colorado scratched across a final run in the ninth against reliever Luke Jackson. Orlando Arcia walked, advanced to third on a double by Mickey Moniak, and scored on a groundout by Hunter Goodman.

The loss dropped the Rockies to a dismal 43-115 on the season, while the Mariners improved to 89-69, solidifying their position in the postseason chase. The teams are set to conclude their four-game series on Thursday.

Beyond the standout performances from Castillo and Raleigh, the Mariners’ offense was a collective force, racking up 14 hits. Canzone went 3 for 4 with a double, Polanco had two hits including his home run, and Rodríguez added two hits and a walk to go with his first-inning homer. For the Rockies, Antonio Senzatela provided a bright spot out of the bullpen, tossing 2 2/3 scoreless innings with four strikeouts.

The final score of 11 combined runs fell under the pregame over/under line of 7.5, a testament to Castillo’s brilliance and the Rockies’ overall offensive struggles. The result was largely in line with projections from Interstat, which had given Seattle a 77.8 percent probability to win and projected a 7-3 final score.
