In a season that has already been rife with debuts, the Mariners promoted their top position player prospect, Colt Emerson, ahead of Sunday Night Baseball, and he's immediately a presence on the Rookie of the Year odds board.

Another rookie has debuted, as the Seattle Mariners have promoted Colt Emerson. The latest 2026 MLB Rookie of the Year odds have him among the leaders on the AL odds board.

The top of that board is extremely tight, as Kevin McGonigle and Munetaka Murakami are neck and neck in a race that may not be decided until the bitter end.

Let's explore the markets and MLB odds for AL and NL Rookie of the Year.

MLB Rookie of the Year news

After the Seattle Mariners placed Brendan Donovan on the injured list, they made a surprise call to promote prospect Colt Emerson to the big-league roster. Hours after the announcement, he was in the starting lineup against the San Diego Padres on Sunday Night Baseball.

While he didn't get a hit in his debut, Emerson scored a run after drawing a walk.

The 20-year-old was hitting .255/.347/.469 with seven home runs and seven stolen bases in 38 games at Triple-A before his call-up. Considering his pedigree, it seems unlikely that the Mariners will send him back to the minors even after Donovan returns, unless he really struggles. 

MLB Rookie of the Year futures bets 

Bet Odds Bet date Units
Cardinals JJ Wetherholt +370 May 11 1
Phillies Andrew Painter +3000 March 24 0.25
Mets Carson Benge +2000 March 11 0.25
Pirates Bubba Chandler +1400 February 25 0.25
Guardians Chase DeLauter +2000 February 25 0.25

My National League bets have all floundered to varying degrees, so I'll cut bait and grab St. Louis Cardinals second baseman JJ Wetherholt for one unit.

I like Nolan McLean at +2500 as a dark horse to win the NL Cy Young, so he's tempting here as a hedge alongside Wetherholt, but I'm going to single out the infielder.

With Sal Stewart scuffling, Wetherholt should have the shortest odds among position players. He's batting leadoff for the Cardinals and is displaying the power-speed combo that had him near the top of draft rankings ahead of 2024 when St. Louis took him seventh overall (an absolute fleecing).

His .250 BABIP also tells me that better days are coming for the .235/.350/.405 slash line. He's also the only qualified position-player rookie worth more than 1.0 fWAR on the Senior Circuit, and some of that comes from his elite glovework at the keystone.

Past Rookie of the Year winners

Previous AL RoY winners

Although all players have an equal chance of winning the AL Rookie of the Year Award, the honor has been claimed disproportionately by outfielders since its inception in 1949. Outfielders have 24 victories compared to 17 for pitchers and 17 for shortstops. Catchers are bringing up the rear with just two ROY victories over the past 73 years.

Previous NL RoY winners

No franchise has won more Rookie of the Year awards than the Dodgers. "The Blue Crew" have claimed 18 RoY trophies dating back to the club's early days in Brooklyn.

However, unlike the AL — where the West has been the recent home of the top rookies — the NL East has housed six of the last 13 RoYs, with a mix of outfielders, infielders, starting pitchers, a catcher, and even a reliever.
