Mandatory Credit: Arianna Grainey-Imagn Images \[/caption\] TACOMA, Wash. - Beginner’s luck can be a blessing or a curse. Or both: just ask Colt Emerson, whose early apparent MLB breakout had a lot to do with early luck in the Show (and whose process has taken a big dive after that luck ran out). It’s not clear how Michael Arroyo - the Mariners’ eighth-ranked prospect according to Baseball America - will be affected by his own good luck over his first week and a half of Triple-A play. But there’s no question that the 21-year-old righty has seen an early comfort boost at his new level as his batted balls keep falling in for hits. “I think there’s a big difference between Double-A and Triple-A, but it’s the same baseball,” Arroyo said. “There’s a different environment, but it’s the same baseball and it’s the same game.” Arroyo got the call-up from the Double-A Arkansas Travelers to the Triple-A Tacoma Rainiers alongside fellow 21-year-old Lazaro Montes. Beyond their age, shared level, and status as top batting prospects, there are plenty of differences between these two. Where Montes is one of the biggest power bats in the minors, Arroyo is a contact-first hitter with a history of good swing decisions. In Double-A this year, Arroyo swung at 79% of pitches in the zone and 29.3% of pitches outside the zone (per TJStats), a difference on par with the most discerning major league batters. During his first nine games in Triple-A, however, he has swung at 78.1% of pitches in the zone and 40% of pitches out of the zone, a much less impressive difference. And yet Arroyo has a .350/.391/.600 slash line through those nine games, going 14-40 with two doubles and two homers. His .364 BABIP won’t continue unabated in the future - and he hasn’t hit the ball particularly hard yet at his new level - but his identity as a contact hitter entails a recognition that sometimes, things won’t fall his way. “I think I am mostly a contact hitter. I’m always focusing more than anything on hitting the ball on the barrel,” Arroyo said. “After you hit it, you don’t have control of it, so I focus more on hitting it on the barrel of the bat.” The hard-hit rates and exit velocities will have to increase, however. He is making a good amount of contact, with just a 20.2% whiff rate (extra notable due to his high chase rates to this point), but his 31.4% hard-hit rate is in the 25th percentile of all Triple-A players and the hardest hit ball he has so far went off the bat at 104.8 miles an hour. For Arroyo, though, hard contact is something that is best to let happen when it does, rather than try to force the issue. He talked about hitting the ball squarely on the bat and letting his own natural strength do the work for him. > [#Mariners](https://x.com/hashtag/Mariners?src=hash&ref%5Fsrc=twsrc%5Etfw&ref=emeraldcityspectrum.com)' Triple-A IF/LF prospect Michael Arroyo on his approach at the dish and whether he's focusing more on power at this point in his MiLB career: [pic.twitter.com/f0SGuXRQna](https://t.co/f0SGuXRQna?ref=emeraldcityspectrum.com)— Callaghan Bluechel (@CalBluechel) [July 20, 2026](https://x.com/CalBluechel/status/2079340684197433570?ref%5Fsrc=twsrc%5Etfw&ref=emeraldcityspectrum.com) Given Arroyo’s track record, it wouldn’t be surprising if he truly adjusts to Triple-A pitching at some point soon. He played with the major league camp during much of Spring Training this year, giving an earlier glimpse into how he can play against some of these major league pitchers. He impressed quite a bit during that time, with a homer and two doubles, and four of his seven batted balls were over 100 miles an hour. He didn’t have any extra-base hits in the World Baseball Classic, but he went 4-13 with a pair of stolen bases. According to Rainiers hitting coach Seth Mejias-Brean, there are a couple holes in his hitting to iron out, but he is impressed with how Arroyo has played so far. “With (Arroyo), I think just handling the situation, so putting good ABs together,” Mejias-Brean said. “Maybe he’s going to have maybe a little bit of challenge with some different fastballs, or just different scouting reports that guys have, or they might bust him in a little bit more, but other than that, they’re (Montes and Arroyo both) pretty elite hitters for their age.” Mejias-Brean worked with Arroyo in Double-A last year, so coaching him again is a matter of tweaking things around the edges and polishing Arroyo’s swing for the majors. “Some cues, for me, it’s just be patient. Try to turn the right dials at the right times,” Mejias-Brean said. “And by turning the dials, we’re not turning it 10%, we’re just doing that 1% each day and \[he can\] just gradually become a big-league hitter.” Arroyo’s bat is the clear strong point in his status as the Mariners’ eighth-ranked prospect, with a hit tool of 60 on the 20-80 scale according to Baseball America. Is is the bat that will make or break his career once he makes the major leagues, but that doesn’t mean defense plays a backseat. He has long been an infield prospect with below average or fringe-average defensive ratings, but with a full infield in Triple-A, he is playing most of the time in left field. Former Mariners outfielder Franklin Gutiérrez, currently a special assignment coach in the M’s farm system, has been working with Arroyo for a while on his outfield skills. “I train a lot with Franklin Gutiérrez, always every game or every time I don’t understand something, I call him, I write it down, and it’s always pertinent," Arroyo said. “He always has good advice, and he helps me a lot.” Arroyo seems like a serviceable left fielder at this point, not a black hole in the position but unlikely to wow anyone with his defense. Still, it offers a range of positional versatility for the young Colombian to fit wherever his eventual team - be that the Mariners or someone else - needs him. And will Arroyo see the big league diamond in 2026? It’s hard to say. He still needs quite a bit of time to fully adjust to Triple-A pitching, after all. There has been speculation that the right-handed prospect might fill in the Rob Refsnyder role at some point towards the end of the year, but he doesn’t have much of a lefty-righty split this season and has historically tended towards reverse splits (batting better against same-sided pitching) earlier seasons in the minors. It wouldn’t be surprising to see an eventual September call-up for Arroyo, even if it’s only for a week or so after the Rainiers’ season comes to an end later in the month. But the Mariners certainly can’t count on him as a meaningful boost this year. But if or when Arroyo starts finding consistent barrels in Triple-A this year and settles his opening patience hiccups, there will certainly be a conversation.
