MLB rookie rankings: Tight races lead to tough choices

The 2026 MLB season has been the year of youngsters. Both leagues have seen loads of bright rookies burst onto the scene, leading to Rookie of the Year races that are teeming with worthy candidates. Come November, these votes will likely be the most closely contested of all the major awards.

How can we possibly sort through all this talent to find the top rookies in each league thus far? Well, we're going to try - and we'll probably make some people mad along the way. Here's a look at where the 2026 Rookie of the Year races stand after four months of play.

American League

5. Payton Tolle, Red Sox, SP

Tolle, who made his MLB debut late last year, joined the Red Sox rotation in early April after three starts in Triple-A and hasn't looked back. Among AL rookie pitchers with at least 50 IP, the 23-year-old southpaw ranks second in strikeouts, K/9 (9.6), and fWAR (2.3) and third in WHIP, FIP, and BB/9 (2.6). Opponents are also hitting just .191 against his four-seam fastball, which averages 96 mph, and he sits in the 86th percentile for chase rate. Considered a big part of Boston's resurgence, Tolle has allowed more than three earned runs in just three of his 16 starts.

4. Chase DeLauter, Guardians, OF

DeLauter is producing in a variety of ways, quickly establishing himself as one of two standout rookies driving the Guardians' offense. He sits third among qualified AL rookies in RBIs and OPS (.801), fourth in wRC+, fifth in OBP, home runs, and fWAR, and sixth in both slugging and wRC+. The 24-year-old has a tremendous eye at the plate, sporting a 13.6 strikeout percentage that's the lowest among all rookies in the majors. Overall, he's helped offset what Cleveland's lineup has lost due to Steven Kwan's downturn and José Ramírez's injury absence. Between DeLauter and Travis Bazzana, the future of the Guardians' offense is very bright.

3. Munetaka Murakami, White Sox, 1B

Remember all those concerns about Murakami potentially struggling to translate his success in Japan to the majors? Yeah, they're gone now, and 29 teams are kicking themselves for not signing him. Despite missing over a month with a hamstring injury, the former NPB Triple Crown winner leads all rookies in slugging, wRC+, and OPS (.897), ranks second in OBP, and is just one of three MLB rookies with 20-plus homers. He also earned an All-Star nod, competed in the Home Run Derby, and has become a fan favorite on a bright young team exceeding all expectations. The White Sox could have at least three rookies in these top five spots, but Murakami has elevated himself above his teammates.

2. Parker Messick, Guardians, SP

Forget Rookie of the Year: Messick's putting together a legitimate AL Cy Young case. The 25-year-old southpaw ranks top-five on the AL pitching leaderboards - all pitchers, not just rookies - in ERA, fWAR, and opponents' average, while he sits top-10 in innings, WHIP, and FIP. He's also allowed only 11 homers over his 20 starts for a 0.84 HR/9 rate. And Messick isn't exactly overpowering hitters with his velocity: opponents are batting just .138 with a .214 SLG against his fastball, which sits in the 33rd percentile. In any other year, a rookie on pace to be a Cy Young finalist would be running away with this award. But with an incredible 2026 rookie class, Messick is the runner-up for now by the length of a fingernail.

1. Kevin McGonigle, Tigers, SS/3B

There's a reason the Tigers handed McGonigle $150 million after 17 big-league games. The 21-year-old sits fourth in the entire AL in OBP, fourth in fWAR, fifth in hits and walks, and ninth in runs scored. Demonstrating remarkable poise at the plate, he's taken more walks (63) than strikeouts (61). Defensively, McGonigle's been brilliant, posting positive numbers at both shortstop and third base, allowing the Tigers to use him at either position. So, besides flipping a coin, how do you decide between a rookie vying for a Cy Young and a rookie vying for an MVP? Here's our logic: Messick's a major part of a potential division-winning Guardians team, but he has a lot of help. McGonigle, by contrast, is one of the only reasons Detroit is still clinging to life. In a race this tight, being your team's MVP is a fair tiebreaker.

National League

5. Sal Stewart, Reds, 1B/3B

As the lone first-year NL player with 20-plus homers, Stewart is the NL's premier power-hitting freshman. He also leads all rookies in RBIs and extra-base hits (44), while he tops NL rookies in doubles (23), walks (46), and total bases (184) and sits third in OPS (.799). Though Stewart isn't the fastest as a 6-foot-1, 224-pound first baseman, he's more athletic than you might expect, stealing 11 bags in 14 attempts. Additionally, he's proven to be versatile defensively, making 40 appearances at third base and even seeing time at second. Stewart garnered an All-Star nod in 2026, and you get the feeling that it's the first of many.

4. Nolan McLean, Mets, SP

This season's gone horribly wrong for the Mets, but at least they have McLean. Cementing his status as their ace of the future, he leads all rookie pitchers in strikeouts and has recorded the best K/9 (10.7) and opponents' average (.202) among qualified freshman NL hurlers. He's done a great job of limiting the long ball, allowing only 10 homers in 113 1/3 innings. Although he's hit an NL-leading 13 batters and has a BB/9 rate above three, McLean has almost single-handedly kept New York's rotation afloat while giving a terrible team the chance to win every five days.

3. TJ Rumfield, Rockies, 1B

Colorado acquired Rumfield - a former 12th-round pick with no big-league experience before 2026 - from the Yankees for reliever Angel Chivilli in a minor transaction in January that's become a heist for the Rockies. The 26-year-old leads all qualified NL rookies in average, on-base percentage and total hits, while he ranks second in RBIs, extra-base hits (37), and fWAR, and third in homers. For those who think he's just a product of his environment, Rumfield's splits are fairly even - an .880 OPS with eight homers at Coors Field, compared to .852 and five homers on the road. He should also be among the favorites to win the NL Gold Glove at first base, as his eight defensive runs saved lead the majors at the position. Not bad for a guy few had heard about six months ago.

2. JJ Wetherholt, Cardinals, 2B

Like McGonigle, Wetherholt received a large rookie extension from his team and has lived up to the billing. The Cardinals star ranks second among NL rookies in homers and hits (99) and is fifth in OBP. He's one of only two NL freshman with more than 2.0 fWAR. Additionally, Wetherholt's 15.8 strikeout percentage is offset by a walk rate of 9.9%, indicating that his excellent batting eye will only get better with time. Defensively, he's been a wizard, tallying an MLB-best 18 outs above average and 13 defensive runs saved at second base, making him the NL Gold Glove front-runner. Wetherholt's all but assured of being a finalist for NL Rookie of the Year, and he could very well win this award.

1. Foster Griffin, Nationals, SP

Griffin, who turns 31 on Monday, is the most remarkable story of the season. Injuries limited him to just seven big-league appearances between 2020 and 2022 before he signed with Japan's Yomiuri Giants and turned into one of NPB's best pitchers. His success prompted the Nats to hand him a one-year deal this past winter. Since returning stateside, Griffin has posted the NL's fourth-lowest WHIP and ranks among the top 10 in innings, ERA, BB/9 (2.1), K/BB ratio (4.11), and wins (11), while maintaining a K/9 above eight. Because he had such limited time in the majors before going overseas, Griffin entered this season still eligible as a rookie. Assuming he stays in the NL past the trade deadline, Griffin's done enough to overtake the crowded field and become arguably the most shocking Rookie of the Year winner in the award's history.
