The Iowa Hawkeye Baseball program continues to produce solid pitching prospects. This past season, the Hawkeyes improved in multiple pitching statistics under first-year pitching coach Sean Kenny.
Iowa jumped from No. 123 to No. 16 in team earned run average (ERA), No. 134 to No. 27 in WHIP, and No. 147 to No. 51 in strikeout-to-walk ratio.
As the Iowa pitching staff continues to improve, two former Hawkeye pitchers aim to make names for themselves in Major League Baseball.
Former Iowa lefty pitcher Jack Dreyer has been a revelation for the Los Angeles Dodgers this season. Four years after going undrafted and signing with the Dodgers, Dreyer made the team out of spring training.
Before the mid-way point of the 2025 MLB season, Dreyer has turned heads. He is 2-2 with a 2.78 ERA and 35 strikeouts in 35.1 innings pitched. He has slowly become one of the Dodgers' most reliable bullpen arms.
Another former Hawkeye, pitcher Adam Mazur, just got his call to the Show.

Mazur was with the Hawkeyes for one season (2022) before the San Diego Padres drafted him with the No. 53 pick in the 2022 MLB Draft. In his lone season with the Hawkeyes, Mazur went 7-3 with a 3.07 ERA and 98 strikeouts in 93.2 innings (15 starts).
After being drafted by the Padres in 2022, Mazur made his MLB debut in 2024. He made eight starts and had a 7.49 ERA with 22 strikeouts in 33.2 innings.
In July 2024, Mazur was dealt to the Miami Marlins as part of a package deal that sent left-handed pitcher Tanner Scott and right-handed pitcher Brian Hoeing to San Diego. Mazur finished the season for Miami's Triple-A affiliate, the Jacksonville Jumbo Shrimp.
Before being re-called by the Marlins, Mazur posted a 3.62 ERA with 55 strikeouts in 59.2 innings for the Jumbo Shrimp.
Mazur could start for the Marlins in their Wednesday night game against the Philadelphia Phillies. The game takes place at 5:40 p.m. Central Time in Miami, Florida.
