LHP Zack Ziroli (Downers Grove North, 2025) impressed throughout our brief look. Upside frame, listed at 6-foot-1, 175-pounds with room for added strength. The southpaw worked his fastball up to 82 mph, playing with heavy run/sink at times. He paired the fastball off a big-breaking curveball in the mid-60s, landing it for strikes and even back-dooring some hitters with it.

9/23/23

LHP Zack Ziroli (Downers Grove North, 2025) is an uncommitted two-way that provided more than enough for his team this weekend on the mound. Working out the stretch, the 6-foot-1 southpaw demonstrated strong poise and attention to detail throughout clean and difficult innings. Mixing between a 81-82 mph fastball and a 66-67 mph sweeper, Ziroli was able to keep the hitters off-balance and created swing and miss.

8/08/23

LHP Zack Ziroli (Downers Grove North, 2025) was recently a winner at the Northwest Suburban Open this summer, and gave another intriguing look at the Illinois State Games. Ziroli is an athletic 6-foot, 175-pound southpaw that moves well around the mound with an easy, fluid arm action. His fastball primarily worked in the low-80s with carry up in the zone (T2455 RPM), and he spun a tight curveball in the high-60s with late bite to get swings and misses around the zone (T2715 RPM).

7/11/23

At 6-foot-1, 170-pounds LHP/OF Zach Ziroli (Downers Grove North, 2025) was a two-way winner from this event. Offensively, Ziroli flashed bat strength at the plate from an uphill right-handed swing that worked gap-to-gap as a result. He played with bounce and an intentful first step from the outfield, flowing freely throughout his defense workout. Ziroli showed a loose arm that peaked at 84 mph on his best bullet and hopped on the mound later on, pitching in the low-80s with his fastball while mixing in a mid-60s curveball, too.
