Griffin Canning, once seen as a fading prospect, is writing a new chapter with the New York Mets in 2025. After a rocky season and uncertainty at the start of his career, Canning’s transformation into a key starter has made him one of baseball’s emerging headlines.

From Uncertain Future to New Opportunity

After a challenging 2024 season with the Angels that saw Griffin Canning lead the American League in earned runs, many believed his best days were behind him. The Braves acquired him as part of a trade but soon non-tendered him, leaving his career at a crossroads. However, the Mets saw untapped potential, signing Canning to a one-year, $4.25 million deal before Christmas. He was initially viewed as a depth piece, someone to fill in if injuries struck the starting rotation. As Metsmerized Online notes, that opportunity arrived quickly when the team lost two starters early on.

Reinventing a Pitcher: The Mets’ Secret Sauce

The turnaround has been nothing short of remarkable. Under the guidance of the Mets’ coaching staff, Canning didn’t simply try to throw harder. Instead, he changed how he pitched. By increasing his use of the slider and mixing in his changeup more often, he began keeping hitters off balance. This strategic shift not only improved his slider’s effectiveness—with a 32.4% whiff rate—but also bolstered his fastball and changeup. According to an in-depth Yahoo Sports analysis, the change in approach made all the difference. Canning started to frontload at-bats with his breaking pitches, using his fastball as a surprise rather than a staple.

This shift brought immediate results. Through his first eight starts as a Met, Griffin Canning posted a stellar 2.36 ERA, with a ground-ball rate among the best in the majors. He struck out 24.1% of hitters and dramatically reduced hard contact. He’s become more than a stop-gap—he’s a linchpin holding the rotation together.

The Free-Agent Gem No One Saw Coming

Canning’s unexpected success has drawn attention across the league. Reports from MLB Trade Rumors revealed that the Yankees had strong interest but ultimately missed out. Yankees manager Aaron Boone admitted that the team met with Canning during free agency, but the Mets made the stronger case. Now, as Boone and others look on, Canning’s resurgence only highlights how valuable the Mets’ vision has been.

Why Canning’s Comeback Resonates

Griffin Canning’s story is about more than just statistics. It’s proof that environment and coaching can unlock a player’s true potential. He arrived in New York searching for a chance. With the Mets, he found not just an opportunity but also a system that played to his strengths. His tenacity and adaptability have paid off.
