Montes

Montes and 2B/OF prospect Michael Arroyo are being promoted to Triple-A Tacoma, according to MLB.com’s Daniel Kramer. Montes is the Mariners’ third-ranked prospect and MLB Pipeline’s 26th overall prospect, while Arroyo is the team’s fourth-ranked prospect and MLB Pipeline’s 43rd overall prospect. Montes hit .236/.365/.554 with 25 home runs and five steals in 78 games at Double-A. That came with a 30.5 percent strikeout rate, 18 percent swinging strike rate, and 62.5 percent contact rate, so those numbers will need to improve in Triple-A before he has a legitimate shot to crack the MLB roster.

The 21-year-old Montes is one of Seattle’s top prospects, but he hit just 4-for-25 in 11 spring training games with a 10/1 K/BB ratio. He also hit .213/.319/.433 with 14 home runs and a 30.5 percent strikeout rate in 64 Double-A games to end the 2025 season. He will likely head back there to start the 2026 season.

Montes has busted out of a recent slump with a pair of multi-homer performances over the past week to move into a tie for the minor league-lead with 31 big flies this season. The power-hitting 20-year-old prospect remains a work in progress in the upper minors, but the stratospheric raw power upside is undeniable.

Montes has homered three times in his last four games and is second in the entire minors with 24 big flies this season. The 20-year-old masher’s over-the-fence pop is real and he’s holding his own since being promoted to the Double-A level back in late June with a 1.075 OPS through 16 games. He has a real shot at finishing the year as one of the top 25 prospects in the dynasty landscape.

Montes has torn the cover off the ball this season with a Northwest League-leading 18 home runs through 67 games. The 20-year-old slugging prospect has registered an impressive .268/.387/.572 triple-slash line for High-A Everett and will get his first taste of the upper minors as one of the youngest everyday players in the Texas League. He’s a top-30 range prospect for dynasty purposes with a real chance to finish closer to the top-20 range if he keeps hitting at the Double-A level. Meanwhile, Arroyo has hit .269/.422/.512 with 15 homers and three steals through 65 games. He’s one of the highest-ceiling future power sources at the keystone and is a surefire top-50 dynasty prospect at this stage of his development.

Montes connected for his Northwest League-leading 11th round-tripper of the season on Friday evening with a titanic blast that left his bat at an impressive 114 mph. The 20-year-old corner outfielder will need to tear the cover off the ball as a bat-first prospect to make a significant fantasy impact down the road, but he’s doing everything he can to outperform expectations this season with a robust .966 OPS at the High-A level.

Montes crushed his Northwest League-leading fourth round-tripper of the season on Saturday as his torrid start to the year continues. The 20-year-old slugger has flashed impressive over-the-fence pop and hasn’t had any trouble handling High-A pitching so far, batting .269/.409/.615 with eight extra-base hits, 11 RBI and two steals through 14 games.
