Lowest ERA
Period: 6/15-6/28
Juan Arnaud/Brooklyn – 0.75-WHIP, 12.2-IP, 8-K, 1-BB, 0-ER, 0.00
Juan Arnaud is a right-handed relief pitcher in the New York Mets minor league system (primarily with the Brooklyn Cyclones at High-A as of 2026). He was signed by the Mets as an international free agent from the Dominican Republic (Cotui) in January 2021.
He is listed at 6'2",
164 lbs, born June 22, 2003 (age 23 in 2026).
Arnaud is a bullpen arm who has mostly relieved (very few starts).
2025: Stronger year overall (6-4, 3.40 ERA in 35 G across A and A+), with a standout 2.45 ERA in 29 G at Single-A St. Lucie (including FSL Pitcher of the Week honors). He struggled in a brief A+ stint.
Career minors (through 2026): Around 18-9, ~4.08 ERA in 125+ games, solid strikeout rates (often 10+ K/9 in better seasons) but some control and home run issues early on.
He has improved his command and consistency as he has climbed levels, with low home run rates in stronger seasons. He has also pitched in the Dominican Winter League.
Repertoire
As a reliever, Arnaud relies primarily on a fastball (sitting in the mid-90s, up to 94-96 mph) and a slider. Scouting notes/projected grades (from one simulation-style report) list his fastball around 50/55 potential and slider 45/55, with lower grades on a sinker and cutter. He is described as a flyball pitcher with developing stuff.
His fastball velocity and the breaking action on the slider give him swing-and-miss potential, especially in shorter relief outings. He has shown the ability to miss bats (e.g., striking out 6 in a 2-inning save).
Outlook
Arnaud is a depth relief prospect with a chance to move up as a high-leverage minor league reliever or potential MLB bullpen piece if he refines command and adds consistency against better hitters.
Esteban Mejia/DSL Blue – 1.33-WHIP, 3-IP, 1-K, 1-BB, 0-ER, 0.00
Esteban Mejia is a 17-year-old right-handed pitching prospect (born May 20, 2009, in Peravia, Dominican Republic) who was signed by the New York Mets as an international free agent on June 2, 2026.
He is listed at 6'1" / 186 lbs and throws right-handed.
He was assigned to the DSL Mets Blue (Dominican Summer League) and activated shortly after signing.
Mejia is one of the Mets' lower-profile 2026 international signings. The Mets have invested heavily in the international market (headlined by bigger bonuses for position players like shortstops), but they continue to add pitching depth from the Dominican Republic. At this stage, he is a raw, teenage arm with projection remaining.
Keep an eye on him in the DSL for the rest of 2026. If he shows strikeout ability or velocity like many young Dominican arms, he could rise in the Mets' system.
Omar Victorino/FCL Mets – 1.50-WHIP, 3,1-IP, 2-K, 1-BB, 0-ER, 0.00
Omar Victorino is a right-handed pitching prospect in the New York Mets organization (born June 9, 2005, in Villa Altagracia, Dominican Republic; age 21 as of 2026).
He stands 6'2" and weighs around 170 lbs.
The Mets signed him as an international free agent (UDFA) in January 2022 for a $50,000 bonus.
He has spent most of his pro career in the lower minors, primarily the Dominican Summer League (DSL), Florida Complex League (FCL), and some time with Single-A St. Lucie (FSL). He has shown flashes of promise but remains a developmental arm with command and consistency challenges.
2025 (best full season): 4-2, 3.97 ERA across FCL (2-2, 3.86 ERA in 39.2 IP) and St. Lucie (2-0, 4.15 ERA in 26 IP). Solid strike-throwing with improved control.
He profiles as a potential bullpen piece or back-end starter if he refines his command. Durability has been decent, but he has had rough transitions to full-season ball.
Repertoire
Limited public scouting details are available, but reports from his early U.S. debut (2023 FCL) note:
Fastball: Reaches 95 mph (sits in the low-to-mid 90s range based on early reports). He has some velocity projection with his frame.
Slider: Described as a "big" or "sweeping" slider with good movement—his key swing-and-miss pitch early on.
One simulation/scouting-style report lists a potential four-pitch mix with room to grow: Fastball (current ~40 grade, potential 55), Slider (35/55), Changeup (30/55), and a developing Curveball (20/30). Velocity in the 93-95 mph range is noted, with a suggested bullpen/groundball role.
He has generated strikeouts (around 9+ K/9 in some seasons) but walks too many (high BB/9, especially in A-ball). The slider appears to be his main weapon to complement the fastball.
Overall Outlook:
Victorino is a low-level depth arm with intriguing arm talent and a projectable frame. 2025 showed progress in the FCL.

Arnaud’s control needs tightening. But he is on a decent upwards trajectory.
One of the Mets' biggest failures has been developing reliable bullpen arms. Relief pitching is the most volatile asset in baseball, and it's also where many teams Spend the most money with the least return. Developing your own bullpen talent is one of the biggest competitive advantages a club can have.
I just hope they don't mess these guys up with too much confusing advise.
