Konnor Griffin forces odds shift with wild spring showing vs. Red Sox

Usually, the swing of the bat changes a single game, or at best, a series. But with his two-homer performance against the Red Sox last week, Konnor Griffin changed an entire system.

The teen phenom upended the betting odds, surpassing the Mets’ Nolan McLean to become the odds-on favorite to win the National League Rookie of the Year Award in 2026. Mind you, Griffin hasn't recorded a single at-bat above Double-A.

The betting aggregate site Vegas Insider notes that the opening odds ranked McLean and the Cardinals’ JJ Weatherholt above Griffin in the ROY race. As of February 28, though, Griffin had firmly taken the lead, cutting his odds from +700 to +250-300 depending on the site.

The shift was abrupt and inextricably tied to Griffin's two-homer game. The odds are finally aligned with the prognosticators who have Griffin as the consensus No. 1 prospect in baseball.

With two swings, Konnor Griffin became the favorite to win the 2026 NL Rookie of the Year Award

The fact that the two homers were Griffin’s only hits in his first five spring games has done little to dim his shine. He’s all the buzz across baseball with Pirates fans crossing their fingers that a contract extension is on the way.

Like his teammate Paul Skenes, Griffin is shouldering immense pressure as the top prospect in baseball, and if the 19-year-old Griffin can manage those expectations, he might follow Skenes’ path. Skenes took home the award in 2024, becoming just the second Pirates player to win the Rookie of the Year. Jason Bay was the franchise’s first in 2004.

The Braves (Drake Baldwin and Michael Harris II) and Dodgers (Cody Bellinger and Corey Seager) are the only NL teams to win multiple ROYs over the past decade. They’re also perennial powerhouses replete with homegrown talent, even if L.A. also seems to buy every superstar that hits the market. If Griffin takes home the ROY, he and Skenes could form the backbone of a contender.

Unfortunately, Griffin’s age may be one point against him when predicting the Rookie of the Year winner. Position players who debut as teenagers, which Griffin will do if he makes the Opening Day roster, tend to experience some growing pains before settling into superlative careers in the Majors. Even if he takes some time to get his feet wet, Griffin’s pair of monster homers suggest he’ll be one of the most exciting players whenever he does make his Bucs debut.
