The World Series opener is setting up as a straight-up speed test: Brewers ace Jacob Misiorowski on one side, Rays slugger Junior Caminero on the other. One brings the hardest fastball in baseball.
The other brings the quickest swing. Game 1 gets the kind of collision you can feel before the first pitch is even thrown.
Misiorowski led all starting pitchers in average fastball velocity in 2026 at 100.6 mph. Caminero paced all hitters in average bat speed at 79.4 mph. That alone makes this feel like best-on-best, but the deeper numbers take it to another level.
Caminero has hit the 75 mph “fast swing” mark on 84% of his swings this season. Misiorowski, meanwhile, throws fastballs two-thirds of the time, and two-thirds of those heaters come in at 100 mph or more. It’s pure velocity from both men, right from the jump.
The volume is staggering, too. Misiorowski has thrown 1,211 fastballs at triple digits in one season, which is nearly 500 more than any pitcher has managed in a year since pitch tracking began in 2008.
Aroldis Chapman had the previous high with 723 in 2016. Among starters, Hunter Greene had the most before this with 337 in 2022.
Misiorowski hasn’t stopped there; he’s been rewriting velocity records all year.
Caminero has delivered the most fast swings of any hitter, with 954. Bat-tracking data only goes back to the 2023 All-Star break, but that’s already the most in a season by anyone so far. If anybody has the bat speed to keep up with Misiorowski’s heat, it’s him.
And then there’s the pure top-end stuff. Misiorowski has reached 105.5 mph this season, a number only Chapman has ever topped, and no starting pitcher has come within two mph of it.
Justin Verlander and Jordan Hicks are the only others to have even touched 103. His first pitch of the playoffs came in at 104.8 mph, a postseason pitch-tracking-era record.
The fastest pitch ever thrown in the World Series since 2008 is 103.2 mph, also by Chapman in 2016. The fastest by a starter is 101.1 mph from Noah Syndergaard in 2015. Misiorowski could break both marks quickly in Game 1.
Caminero is no less serious about the other side of the duel. He’s reached 80 mph or higher on 536 swings this season, more than the entire Brewers lineup combined, which finished with 499. And the pop is real: his homer off Cade Smith in the Rays’ clinching ALCS win came on an 81.2 mph swing, and it was the first homer Smith had ever allowed on his splitter in the majors.
Misiorowski’s four-seamer has been a nightmare all season. He’s piled up 354 swings-and-misses and 168 strikeouts with that pitch, both second only to Gerrit Cole’s 2019 totals of 384 and 193 in the pitch-tracking era. The average velocity on those strikeout pitches was 101.3 mph.
The lone meeting between Misiorowski and Caminero came on April 1, and it looked a little different from what Game 1 might bring. Misiorowski threw only three four-seamers and five sliders across two at-bats, and none of the fastballs were in triple digits. Caminero still struck out once and lined out once, with the slider doing the damage.
This time, though, the expectation is that Misiorowski lets the fastball fly against him, especially after watching how the Guardians attacked Caminero with high heaters in the ALCS. Misiorowski thrives up in the zone, even if the playoffs have brought some whiffs on the four-seamer.
That leaves the door open for Caminero to fight back. Either way, Game 1 opens with the kind of heat that can decide a series in a hurry.

Rays Face A World Series Problem Their Speed May Not Solve
The Rays have spent the season leaning into their speed, and it has been one of the defining traits of their run to the World Series. Milwaukee presents a similar challenge from the other side, with the Brewers and Rays finishing first and second in stolen bases during the regular season and carrying that aggressive approach into October. For a matchup built on pressure, every extra base could matter just as much as any big swing.
Chandler Simpson has been a central part of that identity, giving Tampa Bay another threat every time he reaches. But once the series starts, the running game gets more complicated than simply sending guys and hoping the legs do the rest. Milwaukee has shown real ability to control opponents on the bases, while Tampa Bay has had more trouble keeping runners in check, leaving the Rays with a familiar strength that may not translate cleanly against this opponent.

Rays Face A Franchise Decision With Junior Caminero
Junior Camineros importance to the Rays has only grown as Tampa Bay pushes deeper into the postseason and into the 2026 World Series after knocking out the Guardians in the ALCS. The 22-year-old infielder has become one of the organizations foundational pieces, the kind of player the Rays usually try to identify early and keep for the long haul if the fit is right.
Now comes the familiar Tampa Bay question of whether a breakthrough player becomes a long-term franchise pillar in the same uniform. There is no official extension yet, but the conversations around Caminero point toward a major offseason decision, one that could define how aggressively the Rays move to secure him before the next layer of roster uncertainty arrives.

Brewers World Series Ace Debate Just Got More Interesting
As the Brewers and Rays get set for World Series Game 1 on Friday night in Milwaukee, Joe Maddon has added a little extra intrigue to the matchup by weighing in on Milwaukees choice at the top of the rotation. The former MLB manager, who knows the postseason stage as well as anyone, said he sees Drew Rasmussen as the better opening-night option, even while acknowledging the upside that makes Jacob Misiorowski such a compelling arm.
Maddons reasoning centered on the kind of traits that tend to matter most when October pressure is at its highest. He praised Misiorowskis raw talent, but pointed to Rasmussens maturity and emotional control in big moments as the separator, a reminder that the first move in a World Series can be about more than stuff alone. With the opener looming at 8 PM ET, that debate has only sharpened the spotlight on how Milwaukee plans to attack Tampa Bay from the start. [Read more 🡒]
