Another year, another World Series, and another chance to look at the shapes and sizes of the guys on the mound. This year it’s the Milwaukee Brewers vs. the Tampa Bay Rays. Two organizations that are known for getting the most out of their pitchers, so I was extra curious to see what their staffs actually look like.

As always, all I have to go off of is height, weight, and body mass index (BMI). That isn’t a lot, but it’s enough to show just how many different body types can make it to baseball’s biggest stage.

The Whole Staff

Here’s a quadrant graph of all 25 pitchers on the two World Series rosters. The dashed lines are the averages for the group, which works out to about 6’2.6″ and 211 lbs.

	Height	Weight	BMI
Brewers (13)	6’2.7″	206	26.0
Rays (12)	6’2.4″	215	27.3
Both teams (25)	6’2.6″	211	26.6

The two teams are basically the same height on average, but the Rays carry about 9 more pounds per pitcher.

Compared to Last Year

I went back to last year’s Blue Jays vs. Dodgers rosters to see how this year’s group stacks up. I expected them to be bigger, but it’s actually the opposite.

	Height	Weight	BMI
2025: Blue Jays & Dodgers (24)	6’3.1″	211	26.3
2026: Brewers & Rays (25)	6’2.6″	211	26.6

This year’s pitchers are about half an inch shorter on average and weigh almost exactly the same (less than a pound lighter). Carrying the same weight on a slightly shorter frame bumps the average BMI up from 26.3 to 26.6. So no real change in size, just a bit more compact.

The Outliers

The tallest is a tie. Trevor Megill of the Brewers and Tyler Wells of the Rays both stand 6’8″. That’s over 2 meters for those outside the USA, and the same height as last year’s tallest, Tyler Glasnow.

The heaviest is Tyler Wells at 270 lbs. That’s a 35 lb jump from last year’s heaviest pitcher, Jeff Hoffman (235 lbs).

The lightest is Dustin May at 180 lbs. What makes that interesting is that he’s 6’6″, which gives him the lowest BMI of anyone in the series at 20.8. Aaron Ashby is right there with him at 181 lbs.

There’s no single shortest pitcher. Six guys are listed at 6’0″: Robert Gasser, Logan Henderson, and JoJo Romero for Milwaukee and Freddy Peralta, Ian Seymour, and Cole Sulser for Tampa.

The highest BMI belongs to Drew Rasmussen, who packs 240 lbs onto a 6’1″ frame for a BMI of 31.7.

The 99+ mph Club

This is the part I was most curious about. If you’re going to throw 99+ mph, do you need a certain body type? Here are the seven guys in this series who have hit 99+ in MLB this year.

They’re all over the map. Aaron Ashby is 6’2″ and 181 lbs. Trevor Megill is 6’8″ and 250 lbs. Antonio Senzatela is 6’1″ and 236 lbs, and Jacob Misiorowski is 6’7″ and only 197 lbs. And Dustin May, the lightest pitcher in the series at 180 lbs, is in the club too. Just seven pitchers, and they land in all four quadrants of the graph.

	Height	Weight	BMI
99+ mph (7)	6’4.4″	210	25.3
Everyone else (18)	6’1.8″	211	27.2

On average, the 99+ guys are about two and a half inches taller than the rest of the staffs, but they weigh about the same. That gives them a lower BMI (25.3 vs. 27.2). Being taller tends to be linked with throwing harder in the research, so that part isn’t a surprise. But with only seven pitchers I wouldn’t read too much into it. What jumps out to me more is the range. There clearly isn’t one “velo body type.”

I hope you enjoy this information. Now it’s time to go watch some baseball!
