Dan Hartleb has kept Illinois competitive for 17 years — a feat that requires equal parts stubbornness and development. The Illini went 30-24 with a 14-16 Big Ten record in 2025, and the 2026 roster needs the portal additions and returning core to push Illinois back above .500 in conference play.

Key returnees and transfer portal additions
Naperville product. Illinois' best hitter and the offensive anchor. Does not chase and drives the ball with authority when he gets a pitch to hit.
Champaign native. Athletic shortstop with range and improving offensive numbers. Hits the ball harder than his average suggests — due for a breakout.
Peoria product. Illinois' power bat. 13 home runs led the team in 2025. Needs to raise the batting average but the raw power is real.
Decatur product. Friday starter with a mature approach beyond his years. Pounds the zone with a fastball-changeup combination and rarely walks hitters.
Bloomington native. Veteran Saturday arm who has seen everything the Big Ten can throw at him. Experience is the weapon — he competes in every outing.
Springfield product. Closer with a lively fastball and a competitive edge. Six saves in eight chances — he has earned the ninth inning.
SEC infielder who adds power and versatility. Can play second base or third base. Gives Hartleb lineup flexibility he lacked in 2025.
Big 12 outfielder with speed and on-base ability. Immediately upgrades the top of the lineup.
Sunday starter candidate with a three-pitch mix and the ability to eat innings. Fills a hole that plagued Illinois in 2025.
Experienced left-handed reliever who adds bullpen depth. Can work multiple innings and neutralize lefties.
Nathan Stahl (3.72 ERA, 84 K) is a genuine Friday starter who does not beat himself — 1.8 walks per nine innings tells you everything about his approach. Joey Gerber (3.18 ERA, 6 saves) in the ninth gives Illinois a defined back end. The Stahl-to-Gerber pipeline is the foundation. The question is what happens in between.
Stahl on Fridays, Jack Wenninger (4.21 ERA, 71 K) on Saturdays, and Ryan Webb (from Wichita State) on Sundays. Wenninger is a veteran who competes but gave up too many runs in Big Ten play to be a true conference-caliber Saturday arm. Webb fills the Sunday hole that Illinois tried three different starters for in 2025 — stability alone would be an upgrade.
Gerber closes. Dominic Hamel (from Dallas Baptist) adds the left-handed relief depth Illinois lacked. The middle-relief corps was the weakness in 2025 — a 4.85 ERA in the sixth through eighth innings cost Illinois at least four conference games. If Hamel and the returning arms can get that number under 4.00, the Illini compete for a tournament bid. If not, it is the same story as 2025.
Cam McDonald (.314/.401/.508, 11 HR) carries the lineup. He is the most disciplined hitter in Champaign in a decade — does not expand the zone, punishes mistakes, and can drive the ball out of the park when he gets his pitch. McDonald in the three-hole forces pitchers to be honest with the entire lineup.
Drake Westcott (.269/.349/.468, 13 HR) provides the raw power. 13 home runs are real — the .269 average is what holds him back from being an All-Big Ten player. If he raises it to .285, Illinois has a 1-2 punch in the middle of the order. Marcus Brown (from Missouri, .278/.361/.432, 7 HR) adds depth behind them.
Ty Johnson (from Oklahoma State, .292/.378/.448, 17 SB) upgrades the top of the order immediately. Brody Harding (.281/.358/.402, 14 SB) provides speed and defense at shortstop. The bottom third needs development — Illinois was too easy to pitch through in 2025 once you got past McDonald and Westcott. The portal additions help, but the six through nine holes are still a question.
20–80 scouting scale
Illinois is the program that is always in the conversation but rarely the loudest voice. Hartleb has kept the Illini relevant for 17 years — that longevity deserves respect even when the results are average. The 2026 roster has enough talent to compete for an NCAA Tournament bid, but the margin is thin. McDonald is a genuine All-Big Ten player, Stahl can win a Friday game against anyone, and the portal additions fill real holes. The risk is the middle of the roster — the sixth through ninth hitters, the bridge relievers, the depth arms. If those pieces produce at a Big Ten level, Illinois is a tournament team. If they are average, the Illini are the team that finishes 15-15 in conference play and watches the tournament from home. Hartleb has navigated that thin margin before. He will need to again.
