How Mets Top Pitching Prospect Jonah Tong Fared in First MLB Outing of 2026

The New York Mets' top pitching prospect, right-hander Jonah Tong, made his highly anticipated return to the majors on Friday. And in his first appearance on a big league mound in 2026, the hard-throwing righty showcased exactly why so many fans are excited about his potential.

Tong, MLB Pipeline's No. 36 overall prospect for 2026, twirled three almost-flawless innings of relief in New York's 2-1 loss to the Miami Marlins on Friday. The 22-year-old needed just 28 pitches to get through his three innings of work, giving up no runs on no hits and one walk while striking out two.

This strong outing in Tong's return to the big leagues follows an up-and-down season in the minors for the young hurler. The 2022 seventh-round draft pick has a 5.68 ERA in nine Triple-A starts this year with 55 strikeouts in 38 innings pitched. But his performance on Friday could convince the Mets to keep their top pitching prospect in the majors as the latest addition to the team's recent youth movement.

When the Mets called up Tong on Friday, they also designated veteran reliever Craig Kimbrel for assignment. So, at least for the time being, New York has an opening in its bullpen. But the Mets also recently promoted left-handed pitcher Zach Thornton for his MLB debut this week, so they're clearly looking to see if some of their pitching prospects can take on a role with the big league club.

Tong was called up last year toward the end of the season for his first stint in the majors. He made five starts and posted a 7.71 ERA with 22 strikeouts in 18 2/3 innings pitched. But the young hurler also racked up 179 strikeouts in 113 2/3 minor league innings in 2025, one season after he punched out 160 hitters in 2024. That's part of the reason why so many Mets fans are anxious to see what the 22-year-old can do at the next level.

For now, it's unclear whether Tong will stick around in the majors beyond Friday's outing. And if he does, it's unknown if he'll be used out of the bullpen again or join the starting pitching staff. But either way, the hard-throwing righty stated his case to remain in the big leagues with his latest performance.
