Charting the 2026 Rookie Pitching Class: Part 2

Now that the foundations have been laid and the methodology explained in Part 1 of this series, we can dive deeper into some of these pitchers.

As noted in the previous piece, Corbin Young wrote two breakdowns of individual rookie starters that I will link below:

The first covering Nolan McLean, Bubba Chandler, and Parker Messick. Link here.

The second covering Payton Tolle, Connelly Early, Brandon Sproat, and Trey Yesavage. Link here.

So this will be more of a collective analysis of the rough groupings and what stands out from the composite rating, and whether any deeper stats can further support or provide additional context for fantasy purposes.

The composite z-score rating has provided a solid framework for assessing this group of rookies, and most have now logged enough innings to draw early conclusions from the metrics. It is these pitchers who will receive the bulk of the analysis in this piece, while Gage Jump has looked enticing in his two starts — 12 innings is not quite enough for meaningful metric analysis just yet, but well worth keeping a close eye on.

Tier 1 – Profile + Results

What jumped out was the separation between Payton Tolle, Logan Henderson, and Trey Yesavage. Nolan McLean certainly had the most fantasy hype coming into the year and should be a fantastic fantasy asset for years to come, but has been outperformed by these three so far. So let’s dive into how these three have stood out.

If we take the composite rankings in isolation, it is actually Logan Henderson who has performed best statistically. With the best K-BB%, Z-Contact%, and CSW%, despite having the lowest Stuff+ of the three, it is an interesting observation.  This radar illustrates how they measure up against each other as a group.

Henderson is comfortably still the least owned of this group from a fantasy perspective and, despite his rating, would still be rightly considered the outsider. But the signs are there. He has pitched six innings in just one game so far this season, so he needs to prove he can go deeper into games to be a reliable fantasy asset, but the profile is certainly there to make him a stash or streaming candidate for now. Henderson’s movement profile on his four-seam and changeup is reflected in what are elite Z-Contact%, K-BB%, and CSW% numbers within this rookie class. Paired with a HardHit% that ranks in the top 9% of the league, the profile is genuinely exciting, and this is supported by ERA estimators driven by his fastball.

The one area where there is room to grow is on the ground ball side. If Henderson can add that element to his game, he could develop into a legitimate fantasy option as the season progresses.

Tolle is perhaps slightly hard done by within the composite radar — his HardHit% drags the rating somewhat, but a Barrel% running at an elite clip tells a more complete story about the quality of contact he is actually conceding. It is on the scatter chart where he truly separates himself, his xERA pulling him clear of even Henderson and Yesavage on the y-axis. He has been the standout arm of this rookie class so far this season, and remains available in around half of 12-team leagues, depending on your platform.

Yesavage rounds out the top three. He will look to build on an outstanding 2025, but missing some time at the beginning of the season due to injury means he is still finding his feet in 2026. For a full breakdown, Corbin’s piece linked above covers him in detail.

Tier 2 – Under the radar

The next group throws up some interesting names, each offer something a little different. Trevor McDonald seems to have locked himself into a rotation spot, going at least five innings in every one of his starts bar one against the White Sox. He is a groundball pitcher, so he does not offer much in the way of swing and miss. Because McDonald throws almost exclusively sinkers and sliders, he has produced some pretty pronounced left-right splits, his WHIP differs by 0.50 between sides, and he has struggled against lefties so far. His ground ball rate is elite, and paired with the 40% whiff rate he generates with his slider off the sinker, his CSW% holds up despite the limited swing-and-miss profile overall. The movement on that sinker is the foundation of it all, and combined with a solid Stuff+ rating, means McDonald should offer a decent floor for dynasty or keeper leagues.

At the other end of the pitcher spectrum is the hard-throwing Walbert Ureña. His composite rating is propped up almost entirely by an elite changeup — a 36.7% whiff rate and just 19.6% HardHit% on the pitch tells you hitters are both missing it and making weak contact when they do connect. But the sinker, which he relies on almost as heavily, is getting punished — a 44% HardHit% and .387 xwOBA on the pitch is not a recipe for success when combined with a 93.3% Z-Contact%. Hitters are making contact almost every time it catches the zone. The 22.9% O-Swing% on the sinker reflects a command issue — he simply is not locating it competitively enough outside the zone to generate chases, which contributes directly to his K-BB% drag in the composite. Ureña is caught between throwing it in the zone where it gets hit hard or walking batters. The arsenal has great movement and a clear ceiling but comes with some clear flaws, and right now, both are very visible.

While Ureña is the rawest of this group with perhaps the highest ceiling for deeper leagues, Messick has proven himself the most rosterable of the four right now, his 69.1 innings leading the group by some distance being the clearest signal of that. Prielipp, meanwhile, sits in an interesting middle ground; the profile metrics are there, but the Z-Contact% drag suggests the translation to results is still a work in progress. McLean, as noted, sits somewhere between this group and Tier 1; the underlying profile is closer to the top three than his composite position suggests, and he should be rostered in all formats.

Tier 3

From the bottom quadrant, Brandon Sproat and Connelly Early both sit in an interesting position on the composite, above-average profiles dragged down by their HardHit%, but that is hard to ignore at this sample size. This is reinforced by Early’s 12.4% Barrel% and Sproat’s 9.8%, which is enough for concern rather than simply put down to noise, with 66.1 and 46.2 innings pitched, respectively. The metrics suggest both should be performing better, and they should be monitored, but the contact allowed should indicate to approach with caution. Bubba Chandler is perhaps the most interesting case of the three. The Stuff+ is there at 104.6, one of the better raw arsenal scores in the class, but a K-BB% and CSW% that both drag below average, suggest the stuff is not yet translating into the bat-missing ability and command that his arsenal should produce.

As the season progresses and innings accumulate, a second look at this class will be worthwhile. Several of these profiles are still very much in flux, and pitchers like Jump will be interesting to look at once they have pitched more.

One methodological tweak worth considering for the next edition is moving from qualified rookies to an age threshold; a 30-year-old rookie such as Foster Griffin, and a 23-year-old like Gage Jump breaking through offer very different fantasy outlooks, and an age cut would better reflect the goal of this exercise. A minimum innings threshold could also be added to ensure the sample sizes are meaningful enough to trust the metrics.

A hitter equivalent of this composite would also be something worth exploring, where the same weighted framework applied to batted ball and plate discipline metrics could surface some equally interesting names.

The 2026 rookie pitching class has plenty still to prove, but the composite has given us a framework to separate the signal from the noise — and some of these arms are making a very strong case.
