FRIDAY

MUSKEGO VS. ST. THOMAS MORE - 4:30 P.M.

In the afternoon session to kick things off, No. 11 Muskego battling No. 8 St. Thomas More in a Power 25 matchup. Our staff has seen the Cavaliers multiple times throughout the course of the early season, as the group has continued to impress on the diamond. RHP/INF Sam Mommer (2024; Wisconsin-Parkside commit) has been the star for St. Thomas More on both ends—including rushing his fastball up to 91 mph in prior looks this season. INF/RHP Oliver Gonzalez (2024), OF Bennett Karolewicz (2024; Saint Mary’s - MN) and INF/RHP Brayden Alivo (2026) power an offense that has been able to put up runs against quality competition throughout the year.

(Sam Mommer; 4/9/24)

The Warriors remain undefeated through this past week, using their offense to outlast their opponents. INF/RHP Ben Kuglitsch (2026; Florida State), SS Brock Lulewicz (2024; Wichita State) and INF/RHP Bradyn Horn (2024; Wisconsin-Milwaukee) have been the staples in the lineup for Muskego—powering their way to consistent victories. RHP Tyson Grulkowski (2026) has excited on the mound early on, complemented by the work of Horn. RHP’s Callen Tomsyck (2025) and Dean Stadaucher (2025) were two winners over the weekend who have provided a spark as well. The Warriors are anchored by star freshman C Maddux Lessard (2027), who has created a positive impact right away in his first season.

GREENDALE VS. BROOKFIELD CENTRAL - 4:30 P.M.

Greendale and Brookfield Central will battle at the same time in an intriguing non-conference battle, as the Panthers will attempt to upset the No. 16 ranked Lancers. Greendale has the pieces to do so, led by RHP’s Ben Hites (2025) and Dylan Campeau (2025) in their pitching staff, who can each go win a game single-handedly on the bump. As for the offense, the Panthers have struggled at times early on in the season, but show potential led by MIF’s Jack Bauer (2024; Madison JC) and Cameron Bueno (2025).

(Ben Hites; 2/24/24)

Brookfield Central dropped a tough game to West Allis Hale earlier in the week, but have taken down numerous quality opponents early on. LHP Colton Semmelmann (2025) has shown well on the mound in prior looks, and may see some action on Friday. The left-hander is joined by RHP Vincent Bitter (2026) and RHP/INF Jaxon Clayton (2025) on the bump, two electric right-handers that can provide velocities in the upper-80s with the fastball. Offensively, 1B Aren Robinson (2024; Gulf Coast State College) and INF Braylan Bigler (2025) have been staples at the top of the order for Brookfield Central who have been the igniters on the offensive end.

(Colton Semmelmann; 4/5/24)

SUSSEX HAMILTON VS. WAUKESHA NORTH - 4:30 P.M.

Sussex Hamilton and Waukesha North wrap up the first slate of games to take place on Friday, with each team presenting elite pitching staffs. The Chargers have been able to tally a couple of wins early on this year with the work of RHP Ben Moser (2024; St. Thomas (MN)), who has powered this team to victory early on in the year. 1B/RHP Ethan Hibicke (2025) and INF Nathan Glapa (2025) have been nice compliments to Moser to round some of the standouts on this roster, as they have already notched an upset over Brookfield Central this season.

(Nathan Glapa; 3/16/24)

The Northstars have thrived early on—jumping out to a 4-0 start before dropping a game to Arrowhead on Tuesday. RHP/1B Connor Curtis (2025) and RHP/INF AJ Curtis (2024; Wisconsin-La Crosse) have been the pair of brothers to push Waukesha North out to this hot stretch in 2024. Both get the job done from a two-way perspective—excelling both at the plate and on the bump. OF Cooper Haas (2025) has maintained consistent production from the leadoff spot throughout the early portion of the Northstars’ 2024 campaign. Solid team defense and timely hitting has been the formula for Waukesha North, as they have already notched quality wins over Nicolet, Whitnall and University School.

(AJ Curtis; 7/3/23)

GERMANTOWN VS. HUDSON - 7:30 P.M.

Germantown and Hudson kick off the night slate as one of the most highly anticipated matchups of the weekend. The Warhawks have been tasked with tough competition early on, and have held their own as the No. 17 ranked team in the Badger State this week. They recently defeated Homestead this past Saturday—entering Week 4 hot. Germantown boasts numerous competitive arms—including RHP’s Nicholas Heisl (2024; Wisconsin-Milwaukee), Logan Zaverl (2025) and Lucas Frank (2025), to name a few. They have received offensive sparks at different times this season, led by OF Carsen Dulak (2024; Bryant & Stratton CC), 1B/RHP Carter Gordon (2027) and UTL Grady Cheever (2027) in the lineup. The mix of underclassmen, led by a proven group of upperclassmen that also includes leadoff hitter INF Ryan Ferguson (2024), makes Germantown an electric team to watch as the season rolls along.

(Carter Gordon; 4/5/24)

The Raiders are more of the same—presenting a similar roster. They are anchored by their senior star in C Hunter Carlson (2024; Wichita State), who is a problem for any opponent that Hudson faces. LHP Bradyn Bezanson (2024; Maryville University), RHP Nick Hirsch (2025) and LHP Aaron Schwechler (2024; Wisconsin-La Crosse) have been solid arms for the Raiders in the first month of the season. A pair of underclassmen in RHP/INF Sam Abrahamson (2026) and OF Logan Hagman (2027) have really thrived on the varsity stage, including Hagman, who has slid into the leadoff spot as of late as just a freshman. The leader of this group in INF/RHP Landon Zeuli (2024; Winona State University) rounds out a talented roster that matches up very well with the Warhawks—making for a fun evening at Milkmen Stadium at The Rock on Friday.

(Logan Hagman; 2/10/24)

MONONA GROVE VS. KETTLE MORAINE - 7:30 P.M.

A battle between two of the state’s top teams takes place during the same time session, as Monona Grove heads east to duel with Kettle Moraine. Despite being handed their first WIAA loss of the season this week, the Silver Eagles boast one of the top rosters in the state. They are led by RHP/INF Calvin Moreau (2026), who was the Prep Baseball Wisconsin POTW a couple of weeks ago. RHP/INF Kaden Connor (2025; Xavier) and OF Nicholas Guidici (2024; Parkland JC) have been producing at high rates for Monona Grove early on, and look to stay hot at The Rock this weekend. C Terek Verhage (2025; St. Thomas (MN)) continues to elevate his stardom as one of the top backstops in Wisconsin’s 2025 class. The Silver Eagles can put up runs in a hurry with this deep offensive unit, as our staff is intrigued to see how they handle the Lasers pitching staff on Friday.

(Cal Moreau; 3/12/23)

Kettle Moraine continues to compete despite dropping a couple of games these past couple of weeks. INF JJ Wolbert (2024; Madison JC) and OF Scott Brown (2024) have been the standouts on the offensive end of the ball—powering the Lasers to victories over Verona and Waunakee, who just defeated Monona Grove. RHP Tate Robillard (2025) has taken on the most innings for Kettle Moraine early on, entering the weekend with a 2-0 record against his opponents. LHP Andrew Ishag (2025) has been a nice complement, as the southpaw continues to find his rhythm on the varsity stage. Both rosters prove to play out an even match under the lights on Friday.

(Andrew Ishag; 2/16/24)

MADISON MEMORIAL VS. KAUKAUNA - 7:30 P.M.

Madison Memorial and Kaukauna round out the first slate of games on Friday, as the Spartans are off to a hot start in 2024—debuting in our staff’s rankings at No. 23. Unfortunately for the Madison Memorial, they just dropped their first game of the year to Middleton this week. Despite a setback, the Spartans have excelled as a unit. They are powered by twin brothers RHP/INF Caleb Liggon (2026), a long 6-foot-4 multi-sport star in his first season as a Spartan, and OF Ezra Liggon (2026), a left/left prospect with a similarly high ceiling. Liggon’s work, in addition to the prowess of RHP Cashton Jones (2024; Edgewood College) on the bump early on has gotten this group off on the right foot.

(Caleb Liggon; 3/16/24)

OF Brayden Banyai (2026) is another sophomore who has thrived—taking on a role in the leadoff spot for Madison Memorial. Surrounding pieces and a couple of seniors have stepped up as well—putting the Spartans in a great spot as they enter the weekend at The Rock.

(Ezra Liggon; 3/16/24)

The Galloping Ghosts have tallied a couple of wins in the early season, much of which to do with the work of LHP Bron Schaefer (2026) on the mound. The left-hander is another competitive sophomore in this 2026 class, and has a chance to see some action on the mound and at the plate this weekend. The team is anchored by 1B Christopher DeGroot (2024), who has impressed over the course of his prep career as a pesky left-handed bat that has a knack for finding barrels against opposing arms.

(Bron Schaefer; 3/10/24)
