Prep Baseball Illinois Pitcher of the Week: Jackson Heidemann
April 16, 2024
Sophomore right-hander Jackson Heidemann (Harlem) had himself a week, helping the Huskies to a 3-1 clip with a couple strong performances on the mound. In total on the week, Heidemann went a perfect 2-0 with 10.1 innings, just two hits allowed, 17 strikeouts and two walks. For his efforts, Heidemann has been named this week’s ‘Pitcher of the Week’.
His first outing came in a 26-0 win over Rockford East in which he fired a perfect four innings, striking out 11 along the way with 35 of his 44 pitches being for strikes.
His second outing of the week came against a strong Freeport club, as he fired 6.1 innings while scattering just two hits, two walks and six strikeouts in their 3-0 win. He helped his own cause at the plate in this game as well, finishing the day 1-for-3 with two RBIs.
On the year, Heidemann boasts a spotless 3-0 record with 19.1 innings pitched, a 1.81 ERA, 1.086 WHIP, 33 strikeouts, 11 walks and an opposing batting average of .147. Listed at 6-foot-2, 177-pounds, the right-hander gave our staff an upside look over the winter with a fastball up to 84 mph that set up a low-70s curveball and mid-70s changeup. He’ll be an arm to watch as he continues to develop throughout the high school ranks.
We're thankful for the POTW submissions we received from the coaches across the state. The players who garnered POTW consideration will earn a place within tomorrow's Diamond Notes story, so be on the lookout for that.
