SEATTLE — For the fourth-straight game, a Seattle Mariners starting pitcher registered a quality start in the team's 2-1 win against the New York Yankees on Monday at T-Mobile Park in Seattle.

Monday's quality outing was handled by the most veteran pitcher on the Mariners, 33-year-old three-time All-Star Luis Castillo.

The right-hander threw six scoreless innings Monday. He struck out seven batters, allowed two hits and issued two walks.

Castillo's seventh fanned batter gave him a new career milestone. He reached 1,500 strikeouts with an 82.9 mile-per-hour slider inside to defending American League MVP Aaron Judge in the bottom of the seventh inning.

"(Castillo) was tremendous tonight," Seattle manager Dan Wilson said in a postgame interview Monday. "1,500 strikeouts is outstanding. Congratulations to him on that milestone. Being able to hold this lineup scoreless for six innings, I thought he made just a ton of great pitches."

The Mariners' typical starting catcher, Cal Raleigh, connected for a walk-off RBI single in the bottom of the ninth inning against the Yankees.

The 2025 All-Star was originally slated to get a day off and wasn't in the starting lineup. He received two at-bats during the game after subbing in at designated hitter for Dominic Canzone (who subbed in for Rob Refsnyder earlier in the game).

Raleigh may not have called Castillo's milestone game but he got a firsthand look at it from his spot in the dugout.

"It's amazing," Raleigh said after the game Monday. "He's done an unbelievable job. It's not easy to do in this game and makes it pretty cool that he's able to do that in a Mariners uniform. Very special. Pretty sure he got 1,000 with us too. ... It's always fun to see your teammates — people that you grow very fond of and friends — accomplish feats like that."

Castillo found a great plan of attack early on with Seattle's backup catcher, Mitch Garver.

The pair, who've developed a rapport with each other over the last year, realized that the best results were coming with Castillo's slider and four-seam fastball. The latter of which consistently stayed in the 94-96 mph range.

Of Castillo's 95 pitches, 61 were fastballs (55 four-seam, six two-seam) and 32 were sliders. He fanned five batters with his four-seamer and two with his slider.

"(Castillo and Garver) were on a really good page today," Raleigh said. " ... Had a really good slider going. Obviously had the good four-seam, as well. Mixing some sinkers and changeups. (Garver) knows these guys just as well as I do. He's a great baseball mind, has been around a long time."

The Mariners will try and continue off the foot set by Castillo and secure the series win in game two of the set at 6:40 p.m. PT on Tuesday. Logan Gilbert will start for Seattle and Max Fried will start for New York.
