Can Misiorowski Restore His Fastball Whiffs Against the Rays in World Series?

Jacob Misiorowski’s ability to recover his fastball swing-and-miss could be a key factor for the Brewers in the World Series. Milwaukee won both of his postseason starts, but he failed to complete five innings in either outing as opponents extended at-bats and drove up his pitch count. An MLB.com analysis highlights a sharp decline in his four-seam whiff rate, from 40 percent during the regular season to 16 percent in the playoffs. Velocity has remained exceptional: his postseason fastball averages 101 mph, and he exceeded 104 mph in both starts. Of his 122 fastballs, 96 reached at least 100 mph. Hitters have fouled off 51 pitches across 94 total swings against him. Even when chasing four-seamers outside the strike zone, they have missed only once in 15 swings. Location is one possible explanation. The analysis identifies more fastballs drifting inside against right-handed hitters and toward lower or central areas against left-handers, rather than reaching his preferred high, outside targets. Opponents have also shortened their swings, particularly with two strikes. The Rays’ strong contact skills could make them a demanding matchup. Still, these postseason numbers cover only two starts and do not establish a lasting change in Misiorowski’s ability. More precise fastball placement could help turn foul balls back into misses, reduce lengthy battles and allow him to work deeper into games as Milwaukee pursues its first championship.
