NY Met prospect returns from injury, plus 2 other key prospect updates

After a week or two of action across the New York Mets’ system, things are taking shape. Some players are gaining momentum, while others are still finding their stride. This week, we spotlight a first-round pick, a young outfielder, and a right-hander eyeing his MLB debut this season. It’s still early, but these are the players to watch as their stories continue to unfold.

The latest on Brandon Sproat

Brandon Sproat is back at Triple-A Syracuse and working to build a case for the next step. In three starts for Syracuse, he’s posted a 5.23 ERA and 1.26 WHIP over 10 1/3 innings, striking out 11 and walking seven. The command has wavered at times, but there’s no questioning the raw stuff. And after a shaky first outing, he's settled into a better rhythm.

His latest start at Lehigh Valley was his sharpest yet. Sproat allowed just one earned run across 4 1/3 innings, giving up two hits, walking two, and striking out six. He threw 75 pitches, 51 for strikes, showing improved efficiency and a better feel for the zone. It’s a small step, but a meaningful one for a pitcher hoping to break through to the majors this season. If he continues to trend upward, the Mets may not have to wait long.

What's Jett Williams up to?

After making 21 outfield starts in 2023 across multiple levels of the Mets’ system, along with 11 more in the Arizona Fall League, Jett Williams has opened the 2025 season locked into the infield. The 21-year-old is splitting time between shortstop and second base for Double-A Binghamton and showing a steady presence at the plate. He’s hitting .240 with a .736 OPS through 25 at-bats, with one home run, three RBIs, and three extra-base hits among his six total. He’s also reached base safely in five of his first seven games.

It’s a measured start for one of the Mets’ top prospects, but nothing is troubling in the early returns. Williams’ quick bat and defensive versatility give him plenty of ways to impact a game. For now, it’s about reps and rhythm and he’s checking the right boxes. It’ll be interesting to see how the Mets handle his usage as the season unfolds, especially with a crowded infield picture at the major league level.

Ronny Mauricio will begin his rehab assignment

Ronny Mauricio is returning to game action for the first time since tearing his ACL in December 2023 during winter ball, making his rehab debut on Tuesday as the designated hitter in the Florida Complex League. The 24-year-old infielder missed the 2024 season following surgery and underwent a second procedure in August to remove scar tissue. While the Mets are easing him back into play, his appearance marks a significant milestone in his recovery journey.

During his 26-game stint with the Mets in 2023, Mauricio hit .248 with a .643 OPS, six extra-base hits, and nine RBIs over 101 at-bats, though he did struggle with strikeouts (31). While his numbers weren’t eye-popping, there were clear flashes of potential. Before his injury, Mauricio had been off to a torrid start in winter ball, batting .441 with a 1.178 OPS.

Though there’s still a long road ahead before he can make an impact on the major league roster, this first step in his rehab offers plenty of hope for both his future and the Mets' plans.
