Jacob Misiorowski's 103.5 MPH First Pitch Sets a World Series Record

Milwaukee Brewers right-hander Jacob Misiorowski opened Game 1 of the 2026 World Series with a 103.5 mph fastball on October 23, the fastest pitch tracked in World Series history (pitch tracking began in 2008), per MLB.com. He went five innings for the win as the Brewers beat the Tampa Bay Rays 3-2. His top public card sales, and the market for Misiorowski cards since, are below.

The Record Pitch

The pitch

• A 103.5 mph four-seam fastball to Yandy Díaz, his first pitch of the night and his fastest of the game, per MLB's Statcast data. It missed above the zone, per AP

The old mark

• Aroldis Chapman's 103.2 mph in Game 2 of the 2016 World Series, per AP

His start

• 5 innings, 4 hits, 1 run, 1 walk and 3 strikeouts on 78 pitches for the win, his first postseason win as a starter, per MLB.com. His two earlier playoff wins came in relief in the 2025 NLDS against the Cubs, per MLB's box score. "Yeah, not perfect," Misiorowski said after Game 1, "but good enough to get a win."

Not his fastest

• He threw 104.8 mph to Fernando Tatis Jr. in Game 1 of the NLDS on October 3, the fastest postseason pitch tracked since 2008, per MLB.com. His fastest tracked pitch is 105.5 mph to the Cubs' Pete Crow-Armstrong on June 26, 2026, per MLB's Statcast game feed

What Sold This Week

Through October 24, no Misiorowski card above $25,000 had sold at Fanatics Collect or Goldin since the Series began. The biggest Fanatics Collect sale from October 20 to 24 was a 2022 Bowman Draft Chrome Gold Refractor auto /50, PSA 10, at $11,100, and that auction closed in the early hours of October 23 ET, before Game 1. A PSA 10 of his 2026 Topps #10 rookie card sold for $300 as a fixed-price Buy Now on October 24, the day after the record. The same card in PSA 10 sold for $276 in the October 18 Weekly.

Our take: the record is fresh, the sales are not yet. His three biggest results landed between July 2025 and August 2026, and his biggest October sale, the $24,196 NSCC 1/1, closed on October 15, before the Series. Paid sales after the Series, not asking prices, will show what the record changed. Our World Series 2026 cards piece covers both rosters, and our list of the most expensive baseball cards shows where the top of the market sits.
