Maxgregori Harvey/DSL Orange –
1.00-WHIP. 3-IP. 3-K, BB, 0-ER. 0.00-ERA
Maxgregori Adrian Harvey is a
young right-handed pitching prospect in the New York Mets organization.
Born: November 12, 2006 (age
19 as of mid-2026) in La Romana, Dominican Republic.
Height/Weight: 6'2" /
180 lbs.
Bats/Throws: Right/Right.
Signed: By the Mets as an
international free agent in January 2024 (minor league contract, reportedly
around a $50,000 signing bonus).
He began his pro career in
the Dominican Summer League (DSL) with the DSL Mets Orange team.
2024: 6 appearances (0
starts), 0-1 record, 6.75 ERA in 9.1 IP, 9 strikeouts, but a high 2.36 WHIP
(including 14 walks). He has pitched mostly in relief, with a couple of saves
noted.
In 2025, he dealt with
injuries (placed on the 60-day IL in May, activated in November).
Control has been an issue
early on (high walk rate ~13.5 BB/9 in limited innings), which is common for
young international signees still adjusting to pro ball.
Harvey is a low-level
prospect with limited public scouting details available.
Franyel Diaz/FCL – 1.33-WHIP, 3-IP, 2-K,
BB, 0-ER, 0.00-ERA
Franyel Diaz is a 21-year-old
right-handed pitching prospect (born December 18, 2004, in San Pedro de
Macorís, Dominican Republic) in the New York Mets organization.
He stands 6'7" and
weighs around 208 lbs. The Mets signed him as an international free agent in
July 2022.
Diaz has pitched mostly in
the lower minors (DSL, FCL, Complex League, and Low-A), with limited innings
due to development and some injuries. Key minor league stats include:
MiLB Career (through
mid-2026): ~3.14 ERA, 108 strikeouts in 91.2 IP, 1.49 WHIP across 37 games (13
starts).
2023
(DSL, age 18): 3.00 ERA in 45 IP (mostly starts), 10.8 K/9, strong strikeout
ability but some walks.
2025 (DSL,
age 20): 4.13 ERA in 32.2 IP, high walk rate (7.7 BB/9) but solid strikeouts
(~10.5 K/9).
2026:
Shifted toward relief; strong strikeout rates
He profiles as a
projectable, high-upside arm with strikeout stuff, though he remains raw with
command and consistency challenges typical for tall, young Dominican signees
working through the complex levels
Repertoire
Early scouting reports
a mediocre fastball (88-90
mph) paired with a plus slider (81-84 mph) that was his standout pitch in the
DSL. The slider featured ride and moderate sweep, generating high whiff rates
(including in-zone whiffs), chases, and strong CSW% against younger hitters.
Later reports (around
2024-2025 development) noted an expanded arsenal as he transitioned and added
pitches for better platoon handling and weak contact:
Fastball(s):
Four-seam and two-seam/sinker. The two-seamer/sinker induces ground balls,
especially to righties.
Slider/Cutter-Slider:
Primary breaker, comfortable for strikes or chases; second-most used pitch in
some looks.
Changeup:
Solid vs. lefties, with swing-and-miss potential when located well (command can
be inconsistent).
Curveball:
Previously used but reportedly de-emphasized or dropped in favor of the new
mix.
The goal with the added
sinker and refined slider/cutter has been to complement his strike-throwing
ability with more ground-ball induction and swing-and-miss options against both
handedness. His height likely aids extension and angle, though it can contribute
to control variability.
Overall, Diaz has the frame
and stuff (led by the slider) to climb the system as a potential starter or
high-leverage reliever, but he'll need to refine command and handle higher
levels.
Ernesto Mercedes/St. Lucie –
1.50-WHIP, 3.1-IP, 6-K, 3-BB, 0-ER, 0.00-ERA
Ernesto Mercedes is a 22-year-old
right-handed pitching prospect (born October 14, 2003, in Pimentel, Dominican
Republic) in the New York Mets organization.
He signed as an
international free agent (UDFA) in January 2022 for a small bonus and stands
6'2", 180 lbs. He remains a minor leaguer and has not debuted in MLB.
Mercedes has shown strikeout
stuff but struggles with control and consistency, leading to high walk rates
and some rough seasons:2022 (DSL, age 18): 0-2, 3.72 ERA, 36.1 IP, 10.2 K/9,
7.2 BB/9.
2023
(FCL/A): 2-2, 3.24 ERA, 33.1 IP, strong K rates (~10-12 K/9) but high walks.
2024 (A,
St. Lucie): 0-11, 5.54 ERA in 65 IP — tough year with command issues (high
walks, 12.3 K/9).
2025
(FCL/A): Much better — 4-2, 3.27 ERA, 44 IP, 11.5 K/9, still elevated walks.
Overall minor-league career:
High-K profile (around 11+ K/9 in better stretches) but poor command (career
~7-8 BB/9 range) and fly-ball tendencies. He has worked as both a starter and
reliever.
He has dealt with injuries
and development list time, which is common for young arms.
He profiles as a fly-ball
pitcher with strikeout upside but needs better control and consistency to
progress. The Mets' player development has helped him improve at times (e.g.,
2025), focusing on command and pitch mix.
Outlook:
Mercedes has the raw stuff
(high Ks, promising breaking pitches) to climb the system but must cut walks
and stay healthy. He's a depth/arm-strength prospect rather than a top-tier one
currently.
PERIOD: 6/22-7/5
Tyler McLoughlin/St. Lucie – 0.40-WHIP, 5-IP, 10-K, 2-BB, 0.00-ERA
Tyler McLoughlin is a right-handed pitching prospect in the New York Mets organization, currently playing for the Single-A St. Lucie Mets (Florida State League).
Born: July 1, 2002 (age 24 as of 2026)
Height/Weight: 6'3", 222 lbs
Bats/Throws: R/R
Draft: 10th round (313th overall) in 2025 by the Mets out of the University of Georgia; signed for $7,500.
He was a two-way player (primarily a position player with pitching) at Emory University (D-III) before transferring to Georgia. At Emory, he had strong offensive seasons (e.g., .352/.463/.697 with 12 HR in 2023) and pitched well in relief. Limited innings at Georgia due to injury in 2024, but in 2025 he posted a 4-0 record, 4.19 ERA, and 27.3% strikeout rate in 19.1 IP.
He is viewed as a relief pitcher with arm strength and some intriguing stuff, though he has limited professional innings and control/command issues so far.
McLoughlin has struggled with results in limited Low-A action:
2025: 2 appearances (1 GS), 7.71 ERA in 2.1 IP (high strikeouts but walks).
He has shown flashes of dominance
Repertoire and Pitching Style
McLoughlin throws from a low three-quarters/slingy arm slot with an effortful, loose/whippy delivery (described as "all arms-and-legs" with a leg kick). This creates some deception but contributes to inconsistent command/control.
Key pitches (per scouting reports around the draft):
Fastball: Sits low-to-mid 90s (averages ~94 mph), touches 96–98 mph. Features good ride/upward life in the zone. He can also cut it.
Slider/Cutter: Mid-80s (high-80s in some reports). Gets late glove-side movement/hop.
Curveball: Low-80s offering for shape/variety.
He has high spin rates across the mix, which boosts the fastball's effectiveness and breaking ball bite. His profile fits a high-upside, strikeout-oriented reliever if he can improve consistency and command.
Overall Outlook: McLoughlin is a recent draftee with promising velocity and movement but is still early in his pro development. He's generating swings-and-misses in A-ball but needs to refine control to climb the ladder.
Alsy Torres/DSL Orange – 0.50-WHIP. 4-IP, 3-K, 2-BB, 0.00-ERA
Alsy Noel Torres is a young right-handed pitching prospect in the New York Mets organization.
Born: October 29, 2007 (age 18 as of mid-2026) in San Jose de Ocoa, Dominican Republic.
Height/Weight: 6'3", 160 lbs (listed as very lean/projectable frame).
Bats/Throws: Right/Right.
The Mets signed him as an international free agent on September 29, 2025, to a minor league contract (typical for many DSL-level signees, with no major publicized bonus).
He began his professional career in the Dominican Summer League (DSL) in 2026, initially bouncing between DSL Mets Orange and Blue squads before settling in.
Torres is an early-stage developmental arm. At 6'3" and skinny, he has significant physical projection remaining.
Parker Carlson/Brooklyn – 0.75-WHIP, 4-IP, 3-K, 1-BB, 0.00-ERA
Parker Carlson is a 23-year-old right-handed pitcher (born February 28, 2003, in Mobile, AL) in the New York Mets organization. He stands 6'2" and weighs 192 lbs. He signed with the Mets as an undrafted free agent in July 2025 after a four-year college career at Auburn University.
Carlson primarily worked as a reliever at Auburn. His senior year (2025) was his strongest: 3-1 record, 4.28 ERA, 17 appearances (27.1 IP), 29 strikeouts vs. just 5 walks, and opponents hit .220 against him. He showed strong control throughout college but modest strikeout rates and some inconsistency. He became the 10th Auburn player from the 2025 class to turn pro.
In 2026, Carlson has split time between High-A Brooklyn (Cyclones) and AAA Syracuse (Mets), mostly in relief with some starts. His minor-league line shows solid control but modest strikeout production so far. He has reached AAA quickly for a recent undrafted signee and has been described by Baseball America as a deep sleeper in the Mets system.
Limited innings and some time on the development list.
He added velocity in pro ball after sitting 90-91 mph in college.
Repertoire
Carlson features a wide repertoire with good control. In limited 2026 AAA looks (per pitch-tracking data):
Cutter (primary pitch, ~45% usage): ~87 mph, high spin (~2310 rpm), good horizontal movement. High Stuff+ rating.
Slider (~25%): ~84 mph, solid movement and spin.
Changeup (~15%): ~86 mph, effective vs. righties or as a change-of-pace.
Sinker/Four-seamer (lower usage): ~90-91 mph.
Overall profile: Average-to-plus stuff potential with velocity up to 93-97 mph (sitting 93-95 in spring 2026 per reports). He profiles as a multi-pitch reliever (or possible swingman) who relies on command and pitch mix rather than overpowering velocity. His tjStuff+ metrics rate favorably, especially the cutter and slider.
Carlson is an unheralded but intriguing depth piece with sleeper upside due to his improved velocity, control, and diverse arsenal. As a recent undrafted college arm, reaching AAA in his first full pro season is a positive sign. He could develop into a middle-relief or high-leverage bullpen option if he maintains the velo jump and sharpens his stuff.

Friday is a fun day as we get to see so much reporting on our minor leaguers. The one thing I have gleaned from these reports is something along the lines of: how the hell can anyone project how these folks will perform at the next level -- whatever that level turns out to be? I have no idea. So I hve come up with a mechanism I will employ until I no longer find it useful. Look at the top performers in AAA who have major league experience. they are often, if not always, the best performing HITTERS on the team, yet they couldn't stick in the majors. If they are beating by a considerable amount your prospects at AAA, be suspicious of what those prospects can do at the majors. Lots of potential defensive replacements and few additions to the regular line-up. Yonny and Pache are best performers at AAA. Only Morabito is in their orbit. He's younger and now has gotten on base 24 games in a row. That tells me he's a talent. Bae is backup material and so in Pache and Yonny.
Looking at pitching is even mre difficult. I want to know on what pitchs tong is givning up the bulk of his homers before I fully evaluate him. I want to see Wenninger get one of those fill in chances at the major league level to see how he responds. And I just love Santucci's stuff and hope someone can make a pitcher out of him. Also desperate to have a look at Voit in AAA, skip AA. No point.
Reimer is next year's minor league question mark. And would love for someone to cut down on Lambert walks.
Everything further down in the minor affiliates is a mystery to me and needs more sorting out, but for Yovoney the catcher. Get development to work on evrey aspect of his game as he is the catcher of the future. The pitchers are Bklyn all do well, but I think it is worth keeping an eye on a couple of them, especially Hurtado.
In all honesty, there is a lot of potential in the minors right now, and most of it St. Lucie and below and some spread out talent at AA and AAA teams -- Morabito and Voit as very good and then some pitchers. How much more can you really expect to get from your affiliates on a yearly or two year period.
My job is simple here.
