Mets prospect Jonah Tong dominates with six one-hit innings, MLB call-up buzz grows

Jonah Tong was overpowering long before the Syracuse Mets let it slip away. The 22-year-old right-hander carried a no-hitter into the sixth inning against the Lehigh Valley IronPigs at NBT Bank Stadium on Saturday, retired 16 straight batters at one point and finished with six innings of one-hit ball, six strikeouts, two walks and 12 swings and misses.

That should sound familiar by now. Tong has turned every recent outing into a louder argument for a promotion, and this one was his best of 2026. It was his seventh start of the season and the first time he reached six innings, a benchmark that matters because the Mets need length as much as they need upside. Syracuse still lost 9-6 after a late collapse, but Tong had already done the part that matters most to a major league club: he controlled the game, missed bats and looked far more advanced than a Triple-A box score usually allows.

The run-up to this start only sharpened the case. Tong struck out seven over five one-hit innings on April 8, fanned 10 over 4 2/3 innings on April 15, punched out nine in 5 1/3 innings on April 22 and added six more strikeouts over 4 2/3 innings on April 26. By the time he took the ball against Lehigh Valley, he had 44 strikeouts, tied for the most in the minors, and his stuff was still playing the same way it has all spring: fastball life in the 94-97 mph range, a steep arm angle and a changeup that has taken a clear step forward.

The Mets already know the name. Tong is their No. 2 prospect on MLB Pipeline’s 2026 list and was listed as the No. 42 overall prospect in baseball in the MLB recap, with a player page slotting him at No. 46. He is from Markham, Ontario, was drafted by the Mets in the seventh round in 2022 out of Georgia Premier Academy and entered spring training on the 40-man roster, which means the call-up path is already there when the Mets decide they need another arm.

And the need is real. MLB noted that New York’s 2025 rotation issues were a major reason the club missed the playoffs, and by late April the big-league starters ranked 19th in MLB with a 4.24 ERA and a 10 percent walk rate. Kodai Senga and David Peterson have been part of that uneven picture, which is why Tong’s performance landed with extra force. He is not just throwing well for Syracuse. He is making it harder and harder to justify keeping him there.
