Chicagoland Open: Pitcher Analysis


By: Illinois Scouting Staff

On Sunday, Aug. 21, the PBR Illinois team hosted the Chicagoland Open at the Triton College in River Grove, Ill. The open event featured close to 90 prospects from all high school classes (2023-2026), and gave our staff an ample look at a number of prospects to follow moving forward.

In the week that followed this event, we produced post-event analysis that includes performance highlights inside of our Quick Hits story, a look at the traditional stats measured within our Statistical Analysis piece and some other measurable data inside our Data Dive.

A couple 2026 graduates that stood out from this event were RHP Antonio Brown Jr. (Homewood-Flossmoor) and RHP Joshua Kursell (Judah Christian). Brown showed off some of the most impressive arm-strength in the entire event for his age, reaching up to 81 mph with a raw delivery. With some guidance on the mound and with his mechanics, Brown could certainly add a notable amount of velocity to his already impressive fastball. Kursell also showed to have a strong arm, reaching just over 79 mph with his fastball and showing some feel for a curveball/changeup combination. At 6-foot-1, 150-pounds, there is plenty of room for Kursell to fill out and add on strength in the coming years.

One of the more polished 'pens on the day came from LHP Ryan Greifelt (Notre Dame, 2023). The Webster University commit brings three quality pitches to the table, painting his arm-side of the plate routinely with all three offerings. His fastball sat right in the 81-82 mph range (T18.5 IVB) and set up his 77-78 mph changeup, selling the pitch with arm-speed and playing with fade away from right-handed bats. His curveball can reach over 2,400 RPM at times and plays with tight 1/7 action, thrown for strikes and can also be used to put hitters away when kept under the zone. 

One of the more imposing figures to step onto the mound in the event was RHP Connor Mulcrone (Lyons Township, 2023; Loras College). The 6-foot-4, 195-pound right-hander appears larger than his listed height and sequences his levers consistently down the mound. He worked his fastball up to 81.8 mph with over 2,300 RPM at times, also boasting a spin score of 28.3 which is well above-average. His curveball and slider look to have swing-and-miss potential, both flashing depth and late action to the bottom of the zone. 

RHP Michael Boenzi (Lake Zurich, 2025) came away a winner from the event as well. The 6-foot, 170-pound right-hander reached up to 80 mph with his fastball, while also reaching over 2,400 RPM on his curveball. 

Now, lets dive into the scouting reports from the event.
