The Mets player development system has taken significant strides over the last couple of years, as evidenced by the trade deadline the team was able to have. To acquire Gregory Soto, Ryan Helsley, Tyler Rogers and Cedric Mullins, the Mets surrendered 10 prospects, and only one of them would have made the updated top 10 prospects. Quite a few would have made this top 30, but the Mets were able to have an aggressive deadline and still retained all of their top, top prospects.
Naturally, this has made the Mets system shallower than it was, but there are plenty of new names on this list that weren’t on our preseason top 30 list who are having standout seasons. On the other side of the coin, the top of the system is in as good of shape as it has been in recent memory.
All of the top five belong on top 100 lists, and you can make an argument for any of the top three to be ranked as the top prospect in the system. Importantly, I think the top young players are getting close to the big leagues, whether that is this year or next.
Here is my post-draft / trade deadline Mets top 30 prospects list:
1. INF/CF Jett Williams
After missing most of the 2024 season with a wrist injury, Jett has bounced back to look like himself. As of this writing, he is hitting .278 with an .870 OPS with Double-A Binghamton and is the only player in minor league baseball with 25+ doubles, 25+ stolen bases and 10+ home runs.
The well-built 5-foot-6 Williams has above average bat-to-ball skills, plus plate discipline, and average, flashing above average power. He is a plus runner who can make an impact on the basepaths and can handle all three up-the-middle positions. Most evaluators I speak to prefer him at second base to center field, but Jett’s versatility is valuable. He is the type of player you can see being a dynamic top-of-the-order threat.
MLB ETA: 2026
2. RHP Jonah Tong
What more is there to say about Jonah Tong? He has gone from a seventh-round pick with some raw pitch metrics to an ascending prospect to genuinely one of the best pitching prospects in Minor League Baseball. In 92 innings as of this writing, Tong is second among minor league pitchers with at least 90 innings pitched in ERA (1.66). He leads all minor league pitchers in strikeouts with 146, strikeout percentage at 40.6 percent, and is third in WHIP (0.80).
His repertoire features a fastball that will sit 93-95 and touch 97 mph with elite carry on it, generating north of 20 inches of induced vertical break. He has an…
