Jacob Misiorowski lit up Milwaukee on Friday, launching a first‑inning fastball that registered 105.5 mph against Chicago’s Pete Crow‑Armstrong. The delivery shattered his own record for a starter in the pitch‑tracking era and tied for the third‑fastest ever recorded. Milwaukee rode the heat to a 6‑2 victory over the Cubs.

The Brewers opened with a 103.1‑mph strike, followed by 104.3 mph before hitting the record pitch. He retired the next three batters, then surrendered a solo homer to Seiya Suzuki, his first allowed run in 75⅓ innings. The Cubs drew four walks, pushing his count to a season‑high 107 pitches.

Despite the velocity, Misiorowski’s control wavered; he issued four walks and a batter‑on‑base‑induced pitch count climb. He finished six innings, striking out eight Cubs and matching his season‑high four walks. A 102.8‑mph fastball sealed the win, fanning Ian Happ with the bases loaded.

The performance pushed Misiorowski’s 1.45 ERA into the lowest tier for a starter’s first 16 games in half a century, trailing only Trevor Rogers and Nolan Ryan. Manager Pat Murphy joked about a speed limit, while Misiorowski claimed 106 mph is achievable. Milwaukee’s offense, sparked by Garrett Mitchell’s two‑run homer, secured the win.
