20-Year-Old ShortstopSS
Seattle Mariners AAA
2026 Fantasy Outlook
Barring a surprise offseason move, Emerson has a real chance to be the Mariners' starting third baseman as early as Opening Day. He has always been young for his levels while projecting for at least above-average power and with at least above-average hitting ability. His run in the second half of 2025 was perhaps his most impressive stretch to date, slashing .307/.405/.515 with nine home runs, nine steals (on 11 attempts), an 11.3 percent walk rate and a 17.5 percent strikeout rate in 59 games across High-A, Double-A and Triple-A. He wasn't at Triple-A long (just six games), but Emerson logged a 64.7 HardHit%, 35.3 percent line-drive rate and 174 wRC+. The lefty-hitting Emerson doesn't turn 21 until after the All-Star break, so while he isn't an elite athlete, he's a legitimate hitting phenom and could end up with a plus hit tool and plus power. A shortstop by trade, Emerson will add third base eligibility shortly after his big-league debut, which is a nice bonus. Read Past Outlooks

Inks $95 million contract extension

The Mariners signed Emerson to an eight-year, $95 million contract extension Tuesday, Robert Murray of FanSided.com reports.
Analysis
The deal includes a club option for a ninth year and can top $130 million if all incentives are reached. It's a record contract for a player yet to reach the majors. Emerson came close to winning a roster spot with the Mariners in spring training and now, with a new long-term contract, is a good bet to be promoted to the big club sooner rather than later, though he will remain at Triple-A Tacoma for now, per Ryan Divish of The Seattle Times. J.P. Crawford (shoulder) is on the 10-day injured list with a right shoulder injury that's nagged at him since the start of spring training and faces an uncertain timetable. Leo Rivas has been filling in at shortstop for Seattle, but the club could eventually look to Emerson to fill that void. Emerson, 20, slashed .285/.383/.458 with 16 homers and 14 steals over three levels in the minors in 2025 and is 5-for-14 with a home run in his first three games at Tacoma in 2026.

Past Fantasy Outlooks
2025
2024
Emerson is a really good pure hitter, but the rest of the overall fantasy package is to be determined. He walked more (18.1 BB%) than he struck out (14.0 K%) while hitting .293 as an 18-year-old at Single-A, and he hit .374 in 24 games in 2023 and hit .370 as one of the youngest players in the Arizona Fall League this year. Emerson struggled to a .225/.331/.317 slash line in 29 games at High-A shortly after his 19th birthday, and he missed a lot of time, especially in the first half, with a broken foot. Even amid his struggles in the Northwest League, Emerson boasted a 0.50 BB/K, so he was hardly overmatched. Emerson is a doubles maven, tallying nine doubles in 13 AFL games and 27 doubles in 94 career games in the minors, but he didn't homer in the AFL and has six homers thus far in pro ball. He hits the ball very hard (31.0 Hard%) for a teenage shortstop, but he ran groundball rates over 48 percent at Single-A and High-A last year. Emerson went 15-for-17 on stolen-base attempts in 70 games, so while he only grades as a 50-grade runner, he should be able to chip in double-digit steals early in his career. More over-the-fence power will certainly come, but it's unclear if he'll settle in as a 15-20 homer threat or a 20-30 homer threat.
The Mariners snagged three seven-figure prep hitters in the first 30 picks of the 2023 MLB Draft, and Emerson got the biggest bonus ($3.8 million) and was first off the board at No. 22 overall. A lefty-hitting shortstop, Emerson has already gained good weight since the end of his high school season, up to 6-foot-2 and around 200 pounds. He slashed .374/.496/.550 with two home runs, 10 doubles and eight steals on eight attempts in 24 games across the Arizona Complex League and the Cal League. Emerson has been billed as hit-over-power, and indeed, he had a 17.5 K% and a 14.9 BB% in his pro debut, so the hit tool easily projects as plus. Defensively, he can play shortstop but may move to third base as needed. He isn't a plus runner, but has excellent instincts and gets the most out of his physical tools. Emerson could reach the majors sometime in 2025.
