AL Rookie of the Year Odds

The American League Rookie of the Year betting market has contracted into a massive chalk position. Detroit’s Kevin McGonigle has firmly established himself as the prohibitive odds-on favorite. Listed at -800 on DraftKings, -833 on BetMGM, and a staggering -901 on FanDuel (translating to a 90% implied probability), oddsmakers are heavily exposed on his prospect pedigree and historic production pace.

Backed by public handle and recent on-record praise from manager AJ Hinch – who recently labeled him a franchise “staple” – bettors are forced to decide whether to lay steep vig or hunt for longshot value.

Cleveland’s Parker Messick serves as the lone realistic hedge for those fading the favorite. Currently priced at +600 on DraftKings and +650 on FanDuel, Messick holds steady support from Guardians backers, though the odds gap remains severe.

AL Rookie of the Year Odds Movement Timeline

• September 14 – Kevin McGonigle peaks as the prohibitive chalk, with his outright odds touching -901 on FanDuel, -833 on BetMGM, and -800 on DraftKings. Parker Messick solidifies his position as the primary hedge against the favorite, holding steady at +600 on DraftKings and +650 on FanDuel.
• August 19 – Kevin McGonigle is priced as the massive, odds-on favorite to win the award, dominating the MGM betting board at -400 odds. Chase Delauter establishes his position as the primary (albeit distant) longshot alternative to the favorite, sitting at +3500.
• June 7 – Kevin McGonigle moves to the top of the AL ROY market as the odds-on favorite (-107 average price). Munetaka Murakami (+470), Travis Bazzana (+570), and Samuel Basallo (+660) form the second tier behind McGonigle, with all three still priced short enough to be considered primary challengers.
• May 11 – White Sox 1B Munetaka Murakami has become the +188 favorite, on average, followed closely by Tiger SS/3B Kevin McGonigle (+210).
• February 24 – Yesavage has faded a little as we approach opening day, but his AL ROY have only slid to +370. He’s now being chased by a trio of players at +600: new teammate Kazuma Okamoto, the White Sox’s Munetaka Murakami, and the Royals’ Carter Jensen
• December 3 – Fresh off a fantastic debut in the 2025 MLB Playoffs, the Blue Jays’ Trey Yesavage (+190) has opened as a big favorite to win the AL Rookie of the Year award in 2026. Just behind him on the odds table are Tigers shortstop Kevin McGonigle (+550) and Orioles catcher Samuel Basallo (+700).

NL Rookie of the Year Odds

The National League Rookie of the Year betting market has crystallized around a clear-cut frontrunner. Cincinnati Reds third baseman Sal Stewart has seized command of the race, listed at a prohibitive -3000 on FanDuel. That massive chalk position is corroborated by prediction markets: Stewart trades at 89¢ on Kalshi (89% implied probability) and 90¢ on Polymarket ($35,638 in volume), leaving virtually no daylight for the competition.

New York Mets pitcher Nolan McLean has emerged as the primary challenger, sitting at +1600 on FanDuel—a significant underdog but the only name in the market offering a realistic path to upset Stewart. On Kalshi, McLean trades at just 2¢ (2% implied probability), while Polymarket has him at 1.5¢ (1%), underscoring just how wide the gap between the top two remains.

St. Louis Cardinals prospect JJ Wetherholt rounds out the top three at traditional sportsbooks. Wetherholt sits at +3300 on FanDuel, +4500 on BetMGM, and +5000 on DraftKings. His elite defensive metrics – drawing MLB.com projections for a Gold Glove at second base – have kept him relevant in the conversation.

Prediction markets tell a slightly different story: Kalshi prices him at 9¢ (9% implied probability) and Polymarket at 5.4¢ (4%).

NL Rookie of the Year Odds Movement Timeline

• September 14 – Sal Stewart cements himself as the prohibitive NL Rookie of the Year favorite, listed at -3000 on FanDuel. Prediction markets reinforce the dominance: 89¢ on Kalshi and 90¢ on Polymarket. Nolan McLean emerges as the primary challenger at +1600 on FanDuel, though prediction markets price his chances at just 2% (Kalshi) and 1% (Polymarket), which is only good enough for third. Former favorite JJ Wetherholt holds as the third option at FanDuel, , priced at +3300, though Kalshi has him second at 9¢ and Polymarket second at 5.4¢.
• August 19 – JJ Wetherholt dominates the National League Rookie of the Year betting market, solidifying his position as the odds-on favorite at -161. TJ Rumfield sits as the closest active competitor to the favorite, though his implied probability remains extremely low as a distant longshot priced at +3500 on the MGM board.
• June 7 – JJ Wetherholt dominates the betting board as the clear-cut NL ROY favorite, locked in at a consensus +130. Konnor Griffin holds steady as the definitive second choice, listed at +650 at BetMGM and Caesars, with DraftKings dealing a slightly better +700.
• May 12 – Reds infielder Sal Stewart has crept up the odds table and is now averaging +345 in the latest NL ROY odds. He’s still behind Mets pitcher Nolan McLean, who’s currently averaging +270.
• February 24 – A new favorite has emerged for the NL Rookie of the Year. Pirates’ shortstop Konnor Griffin has been knocking the cover off the ball in Spring Training, belting 3 HR and 6 RBI in six games. Not originally on the board back in December, Griffin is now getting +280 to win the ROY award.
• December 3 – Looking to lock up the #2 spot in the rotation, the New York Mets’ Nolan McLean (+300) has opened as the early favorite to win the NL ROY in 2026. Not far behind McLean are the Reds’ Sal Stewart (+500), the Cubs’ Moises Ballesteros (+700), and the Pirates’ Bubba Chandler (+700).
