The 25 Hardest Throwers in Baseball Right Now

Updated April 16, 2026 | Peak fastball velocity (FF/SI) from Statcast data

Velocity isn't everything in baseball, but it sure doesn't hurt. The ability to blow a fastball past a hitter at 100+ mph is one of the most electric skills in the sport, and the 2026 season has no shortage of arms bringing serious heat.

This list ranks the top 25 pitchers by peak fastball velocity this season, using Statcast-tracked data for four-seam fastballs and sinkers. Of the 25 names below, 19 are relievers or closers and 6 are starters, which tracks with the reality that bullpen arms can let it rip without worrying about pacing through six-plus innings.

The Untouchables

#1–5

The Triple-Digit Club

#6–15
101.4Peak
98.7Avg
The Angels' hard-throwing setup man has been touching 101+ regularly since last year.
101.3Peak
97.5Avg
One of the hardest-throwing starters in the game, regularly sitting 97-98 deep into starts.
101.3Peak
99.0Avg
The former two-sport recruit is averaging 99 as a starter. That's borderline unfair.
101.3Peak
98.4Avg
Once the hardest thrower in baseball, Hicks is back to bringing elite heat from the bullpen.
101.3Peak
98.5Avg
Milwaukee's young flamethrower averages nearly 99 as a starter. Filthy upside.
101.1Peak
99.1Avg
The hardest-throwing lefty in baseball. A 99 mph avg from the left side is absurd.
100.9Peak
98.9Avg
A reliable high-leverage arm throwing gas in the thin Colorado air.
100.9Peak
98.9Avg
Colorado's other gas-thrower, matching Vodnik's numbers exactly.
100.9Peak
98.0Avg
The former top prospect has always had the arm. Now he's putting it together on the Athletics.
100.9Peak
98.0Avg
Oakland's double dose of high-octane relief arms continues.

Notable Names Just Off the List

A few names worth highlighting that didn't crack the top 25 but are throwing serious heat:

  • José Alvarado (PHI, RP) peaked at 100.2. The Phillies' lefty is the hardest-throwing southpaw to just miss the cut.
  • Cam Schlittler (NYY, SP) peaked at 100.1. A young Yankee starter sitting 97 and touching 100 is going to turn heads all year.
  • Dylan Cease (TOR, SP), Taj Bradley (MIN, SP), and Abner Uribe (MIL, RP) all hit exactly 100.0, just barely missing the cut.
  • Roki Sasaki (LAD, SP) peaked at 99.5 and is still building up innings in his first full MLB season.
  • Paul Skenes (PIT, SP) also at 99.5. The reigning NL Rookie of the Year is bringing more heat than most closers.
  • Chris Sale (ATL, SP) touched 99.4 at age 37. Still has another gear when he needs it.

About this list: Peak velocity is the single fastest Statcast-tracked pitch (four-seam fastball or sinker) thrown this season. Average fastball velocity reflects the season-long average for those pitch types. Data sourced from Statcast via our upstream data pipeline and the InsidethePen pitcher database. All pitchers must be on an active MLB roster.

Our Vision For This Site

We've been avid sports enthusiasts and MLB "stats guys" for many years, and we know there are certainly plenty of tools available for all types of baseball analytics and breakdowns.

What we could not find though, was a site that encapsulated the effectiveness of team bullpens. Sure, there are plenty of sites that have advanced Statcast data and include relief pitchers
