The MLB Rookie of the Year odds feel almost settled, but there's enough time for a surprise or two.

JJ Wetherholt is nearing a return from injury, so Sal Stewart's grip on the NL race may not be completely ironclad. Meanwhile, Kevin McGonigle seems to have the AL competition locked down.

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

  • Key Takeaways:
  • McGonigle's steady play
  • Will Wetherholt's return be too late?

MLB Rookie of the Year favorites

Kevin McGonigle, Tigers (82%)

Parker Messick was making inroads in the AL Rookie of the Year race but then stumbled in his most recent outing, allowing three runs on seven hits (two home runs) over six innings against the Tigers. He did rack up a season-high 12 strikeouts in the contest, though, so perhaps his dip is unwarranted.

Ultimately, the extra-steady Kevin McGonigle may win out despite his lower ceiling, simply because his floor has remained fairly high.

Sal Stewart, Reds (86%)

Sal Stewart leads MLB with 107 RBI while slashing .264/.335/.477. He's got 31 home runs and a somewhat surprising 15 stolen bases. 

And yet, he's fourth in fWAR among NL rookies. Some of this can be attributed to his less-than-stellar defensive metrics, but that won't necessarily hurt him. Stewart has played in all 145 games this season, showcasing a durability that few others possess.

Player to watch

JJ Wetherholt, Cardinals (3%)

JJ Wetherholt still leads NL rookies with 4.4 fWAR. His defensive prowess is doing most of the heavy lifting there, as he's probably winning a Gold Glove at second base. He's also filled in at shortstop with Masyn Winn sidelined.

The 23-year-old is aiming to return during the St. Louis Cardinals' upcoming homestand (Sept. 11-20), which could give him some runway to re-establish himself as a contender in this race.

It's worth remembering that the award isn't "best offensive rookie." Even if Stewart has the edge, I'm not sure if it should be an 86-3 advantage in percentage points.

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.

2025 Athletics Nick Kurtz (1B)
2024 Yankees Luis Gil (SP)
2023 Orioles Gunnar Henderson (3B/SS)
2022 Mariners Julio Rodriguez (OF)

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.
