2026 Projections
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
Gets invite to MLB camp
The Mariners have extended Emerson an invitation to major-league camp during spring training.
Analysis
Fellow top prospects Kade Anderson, Lazaro Montes and Ryan Sloan, among others, will join Emerson in big-league camp. Emerson has the best opportunity of all of them to break camp with the big club, as he is expected to be in the thick of the competition for the Mariners' third-base job. The 20-year-old slashed .285/.383/.458 with 16 home runs and 14 stolen bases over 130 games covering three levels in the minors in 2025.

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.
