GROK -

Will Watson is widely regarded as one of their breakout prospects in 2025.

He signed for $281,300, just under slot value.

Prior to USC, Watson attended California Lutheran University and San Joaquin Delta College, where he was drafted in the 20th round by the Seattle Mariners in 2023 but opted to return to school.

Watson's journey to pro ball included a solid college season at USC in 2024, where he appeared in 16 games (9 starts), posting a 3.93 ERA over 50.1 innings with 46 strikeouts, 27 walks, and a 1.411 WHIP.

Watson profiles primarily as a pitcher with starter potential but could transition to relief if command issues persist. He's praised for his competitiveness, athleticism, and ability to miss bats,

2025 Performance and Rise

Watson's first full professional season in 2025 has been a revelation, earning him spots on Mets top-prospect lists. He began at Single-A St. Lucie, where he dominated with a sub-3.00 ERA and high strikeout totals, including a career-high 7 Ks in 4.1 hitless innings in his debut on April 9.

Promoted to High-A Brooklyn in June, he continued excelling (e.g., 8 Ks in 4.2 scoreless innings on June 13), then reached Double-A Binghamton by late summer.

Scouts call him a "wildcard" arm with quick-rising potential, though his fringe-average control (walks remain a hurdle) could cap him as a mid-rotation starter or high-leverage reliever.

ETA to MLB: 2027, but aggressive promotions suggest 2026 is possible.

Pitch Repertoire

Watson's arsenal is deep and versatile, featuring a five-pitch mix that plays well against both lefties and righties. He's experienced a velocity spike in pro ball (up 2-3 mph across the board), crediting Mets development for better extension and spin. He throws from a low-three-quarters slot with a leg kick and long arm action, adding deception. His fastball-centric approach keeps hitters off-balance, and he's noted that opponents "haven't been comfortable" facing it.

Four-Seam Fastball

94-97 mph (avg. 95)

Rise/run profile with elite spin (up to 2,300 RPM); explosive life up in the zone for whiffs. Primary pitch (50-60% usage).

Plus grade; generates swing-and-miss (often his best offering). Peaks at 97 mph.

Slider

84-87 mph (mid-80s avg.)

Sharp, late break with two-plane movement; pairs well with fastball for righties.

Above-average; key for stealing strikes and Ks (recently "working really well"). 20-25% usage.

Cutter

88-91 mph (upper-80s avg.)

New addition in 2025; hard, late cut to tunnel with fastball/slider.

Fringe-average but improving; used as bridge pitch (10-15% usage). "Still finding the right spots," per Watson.

Changeup

87-90 mph (upper-80s avg.)

Tailing action with arm-side fade; firm but flashes plus potential vs. lefties.

Above-average; complements fastball for reverse splits. 10-15% usage.

Curveball

78-82 mph

Deeper, 12-6 break as change-of-pace; less used but adds depth.

Average; situational for early counts or stealing strikes. <10% usage.

Strengths: High-spin fastball and slider combo drives his 25-30% K-rate; athletic delivery aids repeatability. Areas for growth: Command (4+ BB/9) to unlock full potential—refining this could elevate all pitches to plus. Watson's meteoric 2025 rise—from seventh-rounder to Double-A playoff starter—marks him as a Mets system bonus. With the organization's pitching lab, he could emerge as a dark-horse rotation piece by 2027.

14. Will Watson – RHP – (Double-A)

Height/Weight: 6’1″, 185 | Bat/Throw: R/R | 7th Round (203) – NYM (2024) | ETA: 2027

Initially a two-way player at California Lutheran, Watson shifted his focus to the mound full time before transferring to USC where he pitched his way from the bullpen to a starter’s role. His athleticism is evident, working down the mound well, releasing from a roughly 5 foot height with a long arm action that can make it difficult to consistently hit his spots.

Though his fastball averaged 95 MPH and is released from a low slot, it seemed to be relatively easy for hitters to stay on, with a 45% Hard Hit rate allowed and a swinging strike rate below 8%. His best pitch is his plus slider at 85-87 MPH that decimated right-handed hitters in 2025. His equalizer for lefties is an above average changeup, but he will mix in a fringy cutter as well.

Watson has big league stuff and the athleticism to dream on some more, but his command will need to improve to fend off a move to the bullpen.

13. RHP Will Watson

Very, very promising righty. I promise.

A 22 year old 6’1” righty, with a 60 rated FB, he threw 3 brief innings of toe-dipping in 2024, then went just 3-9 in 2025, but with a dazzling 2.60 ERA and 142 Ks in 121 IP.  W/L records in the minors don’t mean a lot, as starters often get pulled after 4 innings or in the 5th, denying them the chance to pick up a W.

In the second half of 2025, Watson had a 2.10 ERA. Pitching at 3 levels, 18 of his 2025 innings were in his 3rd destination in Binghamton.  Could very well be a 2027 Mets starter. A “Sherlock” for a rotation spot, some might say.

WILL WATSON -> Watson is another SP who will draw a lot of attention, becuz of how his arsenal improved across the board & his strong finish. His stuff is electric & he has a future as a SP or RP, which is why the extra attention is based on what the Mets decide to do.

-> Will we see another uptick in VELO on all his pitches? Can Watson take another step forward with his command? If both these things happen you have a potential Top 100 Prospect by season’s end.

Will Watson was selected in the 7th Round of the 2024 Draft out of U.S.C., after spending a couple years of eligibility honing his skills on the JUCO circuit. Watson’s assignment St. Lucie started off very well, before battling control issues during his second month, allowing an uncharacteristic 18 walks for the month of May. 

The Mets still saw enough to promote him to Brooklyn in June, which is when Watson’s season really took off. Watson features an improving arsenal, that features 3 pitches above-average to plus, highlighted by a 4-seam fastball, that generates comparable I.V.B to Jonah Tong.
