Kevin McGonigle has spent most of 2026 looking like the AL Rookie of the Year favorite, and the numbers behind his season are massive. His 6.8 bWAR is tied for seventh all-time among rookie position players, and he’s sitting on a year that already belongs in the conversation for one of the best rookie campaigns ever.
But Parker Messick hasn’t gone quietly.
The Guardians right-hander has put together a rookie season that would be the headline anywhere else. He’s gone 12-9 with a 2.57 ERA and 186 strikeouts, piling up 5.8 bWAR, sixth-best among pitchers in MLB.
His latest big outing came in a win over the Chicago White Sox, when he worked six innings, allowed three runs and struck out eight in a game that pushed Cleveland into first place in the AL Central. Over his last 13 starts, he’s posted a 2.21 ERA with 80 strikeouts and eight quality starts.
Messick’s profile is as sharp as his line. He’s throwing his fastball 41.2% of the time, and hitters are batting just .172 against it.
That pitch carries a 27 Run Value, tied for first in MLB with Jacob Misiorowski and Cam Schlittler’s fastballs. Unlike those arms, though, Messick isn’t winning with elite velocity; his fastball averages 94.3 mph, which is below league average.
Instead, he’s using a six-pitch mix to keep hitters off balance and force weak contact. Among qualified pitchers, his 5.1% barrel rate is second-best in MLB, his 33.8% hard-hit rate ranks eighth, and his strikeout and walk rates sit well above league average at 26.2% and 6.6%.
That kind of season stacks up favorably against recent Rookie of the Year starters, too. The comparison list includes Luis Gil, Paul Skenes, Michael Fulmer and Jacob deGrom, and Messick’s production stands right there with the best of them.
Still, McGonigle’s case is the one that’s been hard to move all year.
The 22-year-old shortstop has produced a season that will land among the best rookie years by a position player. His 6.8 bWAR is tied for seventh all-time among rookie position players, and for primary shortstops it matches Troy Tulowitzki’s rookie season. Among position players in 2026, he ranks third in MLB and first in the American League in bWAR.
At the plate, McGonigle is hitting .277/.378/.428 with 17 home runs and a 130 wRC+, which is second among primary shortstops behind Elly De La Cruz. He’s not chasing much either, with a 19.2% chase rate that’s tied for third-best in MLB, and he’s striking out just 13.5% of the time.
He’s even walked more than he’s struck out, 93 walks to 91 strikeouts. In the leadoff spot, he’s been even better, slashing .308/.409/.494 with a 156 wRC+ and scoring 61 of his 95 runs.
The one area that can be picked apart is his defense. He’s at -4 OAA and -2 FRV, and his arm grades below average, sitting in the 27th percentile.
But at this point in his career, that’s more a note for the future than a real hole in the Rookie of the Year argument. The bat has been carrying enough weight to cover the rest.
So where does that leave the race?
McGonigle still has the edge, but Messick has a path. If he finishes with another eye-catching start, or a pair of them if he’s used on short rest, he can give voters something fresh to remember.
And if Cleveland finishes the job in the AL Central, that could matter too. The Guardians are currently a game ahead of the White Sox, and a strong final push from Messick could leave an impression, especially if his last outing helps decide the division.
The 2024 AL Rookie of the Year vote offers a reminder that these things can get weird. Luis Gil won a tight race over Colton Cowser, even though his 2.9 bWAR only barely topped Cowser’s 2.8.
Wilyer Abreu and Wyatt Langford, who posted 3.6 and 4.2 bWAR, finished sixth and seventh. That doesn’t guarantee a repeat here, but it does show that the final ballot can tilt in surprising directions.
McGonigle and Messick have both been better than everyone on that 2024 ballot. The question now is whether that still leaves enough room for Messick to sneak past the favorite.

Kevin McGonigle Is Making Detroit's Infield Plan Harder To Ignore
Kevin McGonigles rookie season has given the Tigers plenty to like at the plate, but it has also sharpened the question that comes with so many young infielders: where does he fit best? Detroit has seen the offensive promise, and it has also watched the defensive growing pains pile up, with McGonigle splitting time between shortstop and third base while committing 19 errors. For a club trying to sort out its infield beyond the moment, that mix of upside and uncertainty makes him impossible to ignore.
The Tigers have reason to think the answer may already be pointing in one direction. McGonigle is viewed as a long-term option at third base, a spot Detroit has had trouble locking down in recent years, and the case for narrowing his focus is only growing stronger after the mistakes that have affected games. If the organization wants the bat to keep developing while the glove catches up, the next step may be less about moving him around and more about finally letting him settle in. [Read more 🡒]
Tigers On Verge Of Elimination After Brutal Replay Turning Point
Jackson Jobe gave Detroit a chance to hang around Friday night at Rate Field, but the Tigers could not turn the outing into the kind of win they needed. The rookie right-hander struck out a career-high nine, giving the club a much-needed lift on the mound, yet Chicago still finished off a 3-1 victory that left Detroit staring at the edge of elimination.
The game tilted in the sixth inning, when the Tigers thought they had a tying run in position only for a review to wipe it away. Moments later, Miguel Vargas answered with a home run that pushed the White Sox further ahead and shifted the night firmly out of Detroits favor. For a team trying to keep its postseason hopes alive, it was the sort of replay sequence and immediate fallout that can sting long after the final out. [Read more 🡒]
Justin Verlander's Comeback Push Just Took Another Step For Detroit
Justin Verlander took another meaningful step toward a late-season return when he completed a live batting practice session, a sign the Tigers are still tracking his comeback as the calendar winds down. Detroit has spent plenty of this stretch juggling health and availability across the roster, and Verlanders progress stands out because it keeps alive the possibility of getting one of the most familiar arms in franchise history back into the mix.
Jack Flaherty is also moving toward a rehab start after spending time on the injured list, so the Tigers at least have multiple pitchers in motion as they try to sort out the final weeks. It is still a delicate stage for a club dealing with the usual late-season churn, but Verlanders latest work suggests the next checkpoint is drawing closer, and Detroit will be watching closely to see how much farther the right-hander can push this before the season runs out.
