There may not be a harder award race to pick in sports than MLB Rookie of the Year Awards.
Unlike in the NBA or NFL, where the top draft picks enter the league right away, and the best of the best typically are known from their first game, picking a rookie to win in the marathon of a 162-game season is a much more difficult task.
Often, the first part of the battle is just getting the rookie to the show to make their MLB debut, then it’s a matter of staying up. We have seen Rookie of the Years lead their race wire-to-wire, like Corbin Carroll in 2023, or Julio Rodriguez in 2022.
Other times, a clear-cut Rookie of the Year can be harder to find, like when Jonathan India won in 2021, or even when Luis Gil ended up taking home the award in the American League last year.
All it takes is a few hot months for any player or pitcher to vault themselves right to the top of a Rookie of the Year race. The only question is who will be the young stars that emerge this year.
This page will be your guide to the updated betting odds throughout the season, as we follow along with what is sure to be a thrilling race for both AL and NL Rookie of the Year.

Current Rookie of the Year Award Odds: Top Contenders for 2025
Before we dive a little bit deeper into the races in each respective league, let’s just take a look at the current updated odds from BetMGM in the two Rookie of the Year races.
2025 American League Rookie of the Year Odds
| Player | Team | Current Odds | Last Week’s Odds | Opening Odds | Implied Probability |
| 1. Nick Kurtz | Athletics | Off the board | -5000 | +8000 | Off the board |
| 2. Roman Anthony | Boston Red Sox | Off the board | +1600 | +700 | Off the board |
| 3. Jacob Wilson | Athletics | Off the board | +3000 | +700 | Off the board |
| 4. Cam Smith | Houston Astros | Off the board | +6600 | +8000 | Off the board |
| 5. Jasson Domínguez | New York Yankees | Off the board | +8000 | +600 | Off the board |
| 5. Chandler Simpson | Tampa Bay Rays | Off the board | +8000 | +15000 | Off the board |
BetMGM officially pulled the AL Rookie of the Year award off the market with Nick Kurtz emerging as the runaway favorite with an implied probability of over 99% to win this award heading into September.
The Athletics’ first baseman has not only been one of the best rookies in MLB this season, he’s been one of the most dominant hitters in all of baseball in 2025. Among hitters with at least 450 plate appearances, Kurtz is third in all of MLB to only Aaron Judge and Shohei Ohtani in wRC+ (168), OPS (.998), and wOBA (.418).
Kurtz has launched 33 homers to go with 25 doubles in just 111 games, showcasing his immense power potential. For a rookie to put himself in the conversation with some of baseball’s most prolific hitters is quite an impressive feat. Kurtz has already emerged as one of the best first basemen in all of MLB and is more than deserving of being AL Rookie of the Year.
While Kurtz will take home the hardware, there are still a handful of other rookies worth highlighting who had impressive rookie campaigns.
Roman Anthony, who was recently rewarded with an eight-year, $130 million contract extension, was on an absolute heater with the Boston Red Sox before hitting the injured list with an oblique injury last week.
It was a slow start to his rookie season, but Anthony was slashing a monstrous .329/.419/.512 for a .931 OPS in his last 56 games before hitting the IL. Anthony may not win the award, but he’s put together a mighty fine rookie campaign of his own.
Kurtz’s teammate, Jacob Wilson, was the leader in the clubhouse for this award for the first portion of the season before he hit the injured list just after the All-Star break. The 23-year-old shortstop is slashing an impressive .315/.357/.449 with a 122 wRC+ in 120 games this season and has emerged alongside Kurtz as a building block of the future for the Athletics.
2025 National League Rookie of the Year Odds
| Player | Team | Current Odds | Last Week’s Odds | Opening Odds | Implied Probability |
| 1. Cade Horton | Chicago Cubs | -375 | -155 | +8000 | 78.95% |
| 2. Drake Baldwin | Atlanta Braves | +170 | +135 | +5000 | 37.04% |
| 3. Isaac Collins | Milwaukee Brewers | +8000 | +1000 | Off the board | 1.23% |
| 4. Caleb Durbin | Milwaukee Brewers | +10000 | +8000 | +6600 | 0.99% |
| 4. Jakob Marsee | Miami Marlins | +10000 | +10000 | Off the board | 0.99% |
| 4. Nolan McLean | New York Mets | +10000 | +10000 | Off the board | 0.99% |
The National League Rookie of the Year race is starting to take shape with just six games left to play in the MLB regular season.
Thanks to his sensational play since the All-Star break, Cade Horton is officially separating himself in the race and has emerged as a -375 favorite, giving him an implied probability of nearly 80% to take home the hardware.
Right behind him in odds is Drake Baldwin of the Atlanta Braves, whose odds sit at +170. With an implied probability of just over 37%, it’s developed into a two-man race with just one week left to play in the regular season.
With Isaac Collins essentially dropping off the board after going from a +1000 favorite last week to +8000 this week, it’s between Horton and Baldwin for who will walk away as Rookie of the Year in the National League.
NL Rookie of the Year Odds: National League Favorites
| Player | Team | Current Odds | Last Week’s Odds | Opening Odds |
| Cade Horton | Chicago Cubs | -375 | -155 | +8000 |
| Drake Baldwin | Atlanta Braves | +170 | +135 | +5000 |
Cade Horton is furthering his case to be NL Rookie of the Year with each start he makes, and the betting odds reflect that.
No pitcher in MLB has been better since the All-Star break than Horton. He has the lowest ERA in the second half at a sparkling 0.93, while no other arm has an ERA below 1.00 over that same stretch (min. 50 IP). Since the Midsummer Classic, batters are hitting just .153 against Horton and he has a WHIP of just 0.79 across 11 starts.
Overall, Horton’s ERA on the year continues to fall and is now down to a 2.66 across 115.0 innings (21 starts). With Horton likely to make just one more start before the conclusion of the regular season, there’s a very good chance Horton walks away with the hardware, and rightfully so.
Drake Baldwin will do his best to catch him in the final week, however. Baldwin officially leads NL rookies in fWAR at 2.9, and he is third in wRC+ (123), OPS (.800), and wOBA (.348). In terms of counting numbers, Baldwin has the second-most homers among NL Rookies (18) to go with the most RBIs (76).
Baldwin is trying to put the finishing touches on his terrific rookie campaign, going 11-for-28 (.393) with an OPS of 1.290 across the last week of play. He will need to keep that up and then some to contest Horton for this award. Fans are in for an entertaining final week of play in the National League Rookie of the Year race.
Big-Time Dark Horses for NL ROY in 2025
| Player | Team | Current Odds | Last Week’s Odds | Opening Odds |
| Isaac Collins | Milwaukee Brewers | +8000 | +1000 | Off the board |
| Caleb Durbin | Milwaukee Brewers | +10000 | +8000 | +6600 |
| Jakob Marsee | Miami Marlins | +10000 | +10000 | Off the board |
| Nolan McLean | New York Mets | +10000 | +10000 | Off the board |
While none of these dark horses are in contention to win this year’s NL Rookie of the Year award at this point, there have been a handful of performances worth highlighting.
Isaac Collins may be third in odds behind the top two names, but he deserves so much credit for the incredible season he’s put together with the Milwaukee Brewers.
Collins is third in fWAR (2.5) and fourth in wRC+ (120), OPS (.772), and wOBA (.341) among NL rookies this year. He also has the second-most stolen bases among NL rookies with 16, and he’s provided strong defense in left field to help further his claim for the award.
Unfortunately, Collins is in the midst of a 2-for-24 (.083) stretch over his last nine games, effectively taking him out of this Rookie of the Year race. Still, after not even being on the board to win this award heading into the season, it’s a testament to the year he has put together for him to be in the position that he is currently in.
Collins’ teammate, Caleb Durbin, has emerged as a key bat for the Brewers’ offense. Durbin is second among NL rookies in fWAR at 2.8 and has flown under the radar this season as a top rookie in the National League.
Finally, since Jakob Marsee made his MLB debut on August 1, he is slashing an incredible .319/.386/.527 and appears to be yet another building block in the outfield for the Miami Marlins.
All eyes will be on these top-performing rookies the rest of the way, and fans are in store for an entertaining race to the finish line in the National League.
How to Follow the MLB Rookie of the Year Odds
When betting on awards futures, timing is everything. Knowing when it is right to strike is half the battle in making sure you are finding value on the board. Consistently keeping tabs on the odds each week will show you how a player’s market is fluncuating, which can help you find the right time to place your future’s bet.
At the end of the year, BBWAA voters typically base their criteria on who wins these awards largely on stats, but narrative and team role certainly do factor in. Last year, a great case could have been made for Jackson Merrill, but the narrative and sensation that was Paul Skenes was too much for him to topple. Keeping all those aspects in mind can help you pick the right horse in this race.
