Colt Emerson returns: Rainiers feature one of baseball’s top 10 prospects
The nifty plays at shortstop and patient swings at the plate hardly resemble a 20-year-old.
It can be easy to forget Colt Emerson isn’t yet old enough to order a cocktail or rent a car. The consensus top-10 prospect in baseball is stoic beyond his years and obsessed with defensive fundamentals — an identity shaped by Mariners infield coach Perry Hill.
“Good players don’t get bored of the fundamentals,” Emerson smiled, reciting Hill’s go-to phrase.
“Just be a winning ball player. That’s it.”
Seattle is expected to call up their top prospect in 2026, but the South Sound can see Emerson up close in the meantime. He’ll start his season in Tacoma’s backyard, the starting shortstop for the Triple-A Rainiers at Cheney Stadium.
The big question: How long will he stay in navy and red?
“Honestly, I haven’t thought about (a call-up) much, just because it hasn’t happened,” Emerson said at Wednesday’s Rainiers Media Day, standing inside Cheney Stadium’s Dugout Club. “But the moment’s going to be surreal. I don’t even think I can imagine. It’s one thing they say that you can’t prepare for.
“Honestly, when that day comes at some point, God willing, I’m going to go out there and be the same baseball player I am today.”
Emerson is the No. 9 prospect in baseball, per MLB Pipeline, selected 22nd overall by Seattle in the 2023 MLB Draft at Lumen Field. He missed much of the 2024 season to injuries, but Emerson began the ‘25 campaign with High-A Everett and promptly skyrocketed through the ranks, finishing his first full professional season in the Pacific Coast League Championship Series with the Rainiers.
He still remembers sitting in Tacoma manager John Russell’s office in mid-September, shortly after arriving from Double-A Arkansas. Only six games remained in the minor league season.
“One week is not going to change your season,” Emerson said, recalling his manager’s words. “The support from the guys in the clubhouse was just amazing. So it’s pretty easy to play when you’ve got that kind of support, support from skip.”
In 90 games with High-A Everett last summer, the hit-to-all-fields lefty slashed .281/.388/.453 with 11 home runs and 51 RBI. The numbers were similar throughout 34 games with Arkansas before the Mariners promoted him to Triple-A on Sept. 16, and Tacoma saw the emerging, pull-side power with Emerson’s promising first impression — a three-run blast in his Rainiers debut that night.
“Colt’s a baseball player,” Russell said. “He loves to play. He’s a very hard worker, very attentive. He wants to do the right thing and play the game the right way. In the brief time we’ve had, one of the couple things we talked about was noticing what’s going on around him a little bit more. Fine-tuning his base running, fine-tuning the daily things that he does. Obviously, he can swing the bat really well.
“We’ve talked about it this year already, when things aren’t going the way you want them to go, how we’re going to navigate that. He’s young, and there’s a lot of things he hasn’t experienced yet that we’re going to introduce him to a little bit this year.”
Russell knows just how valuable an entire spring training spent alongside Perry Hill can be. When Tacoma’s manager played for the Texas Rangers in 1992-93, Hill was the infield coach. The pair reunited with the Pittsburgh Pirates in 2009, when Russell managed and eventually hired Hill to the staff. Small world, eh?
“He’s awesome,” Emerson said of Hill. “He coaches you hard. He tells you the truth, and helps you become a winning baseball player. Just the consistency and the fundamentals are key for that. He really hammers the fundamentals, and I think all great players love the fundamentals.”
Emerson was aboard Seattle’s taxi squad for the magical, 2025 postseason run that fell just short of an American League pennant, but did not appear in a game. In 18 games this spring, the 20-year-old hit .268 (11-for-41) with two homers and eight RBI.
Everett, Arkansas, Tacoma, doesn’t matter. Emerson isn’t changing.
“I just learned how to keep baseball fun,” he said. “Even in the dog days of the summer. It’s July 25, and you’ve played 100-some games already. It’s the same thing every single day when you show up to the ballpark.
“Finding new ways of making days interesting or getting to know different guys… things like that. Just being a team guy.”
The Rainiers begin their season on the road, visiting Triple-A Reno for a three-game set that begins Friday afternoon. First pitch is scheduled for 2:05 p.m.
Tacoma’s home opener is set for Tuesday night (6:05 p.m.) at Cheney Stadium, the first of a six-game series with Triple-A El Paso.
SHORT HOPS
— Tacoma enjoyed their best season of the “Rainiers” era in 2025, winning 86 games and dancing to the Pacific Coast League Championship Series with Triple-A Las Vegas. It was the third time in franchise history that Tacoma won 86 games, joining the 1961 Tacoma Giants (97 wins) and 1969 Tacoma Cubs (86).
“It was kind of a struggle for us early,” Russell said. “We had a lot of call-ups, a lot of movement. A lot more than I’ve ever seen, really, but that’s why we’re here. You want to make sure Seattle has what they need.
“How they came together in the second half… It started becoming a mission and goal for them to continue to win and get to the championship. I think that was one of the things that I really was proud of, that they fought through what they did early.”
— Outfielder Rhylan Thomas, 25, thrived at spring training, batting .486 (18-for-37) with increased pop since leading the PCL with 178 hits last season.
“I feel like I’m ready to contribute at the major league level and I wanted to display that the best I could, and I think I did a good job of that,” he told The News Tribune. “I wanted to display my ability to impact the ball a little harder than in previous years.
“I’ve always been able to hit, but I haven’t been able to consistently impact the ball as hard as I would like. That was an offseason focus for me.”
— Outfielder Brennen Davis begins the Triple-A season on the 7-day injured list (hamstring) after a strong showing at spring training, batting .353 with four home runs in 15 games. Russell expects the 26-year-old to return to the lineup as early as next week.
“He’s feeling a lot better,” Russell said. “Hopefully, him and (OF Victor Labrada), we should be looking to maybe get them back toward the middle or end of next week. Progressing well.”
