The WIAA playoffs are coming down to the wire in the Badger State, as Regional play has come to a conclusion after an eventful week. Many of the top seeds survived their first couple of rounds of action—emerging as Sectional contenders come Tuesday, June 4.

With the talent that has evolved and will be showcased on Tuesday, the Prep Baseball Wisconsin staff will be rolling out preview pieces beforehand.

The Oconomowoc Sectional features the heavyweights of Milwaukee’s western suburbs, featuring matchups between the prospect-laden No. 9 ranked Muskego squad and Waukesha North, in addition to perennial state contender No. 6 Arrowhead against Sussex Hamilton. Before the big day on Tuesday at the Lake Country Dockhounds’ Wisconsin Brewing Company Park, check out how the teams line up and find out who to watch from each program.

MUSKEGO (22-5)

The top-ranked Muskego squad cruised into Sectionals with a 6-1 victory over Brookfield Central. For Muskego to advance further, they’ll need more offense from the top four hitters in their lineup in INF/RHP Bradyn Horn (2024; Wisconsin-Milwaukee commit), C Maddux Lessard (2027), SS Brock Lulewicz (2024; Wichita State) and INF/RHP Ben Kuglitsch (2026; Florida State), who combined for a 1-for-11 effort in the first round win, but have produced all throughout the regular season.

The seniors Horn and Lulewicz are both dynamic offensive players with quality defense, providing experience on a team loaded with underclassmen prospects. Both former Future Game participants, Horn sets the table with plus bat-to-ball skills and plus-plus speed, while Lulewicz provides power from the three-spot. Lessard proved more than capable of handling an elite varsity pitching staff as a freshman, cementing his status as the top player in Wisconsin’s 2027 class. Kuglitsch, a legitimate two-way prospect, earned that same title for the 2026 class with his incredible spring performance. For Muskego to make a deep state run, they’ll need production from their top-tier top-of-the-order.

On the pitching side they’ll turn to a combination of Kuglitsch, RHP Tyson Grulkowski (2026) and LHP Joey Shaw (2027), a trio of future high-end prospects. Kuglitsch features an easy upper-80s fastball that reaches 91 mph, along with a plus breaking ball. Grulkowski, the fifth-ranked prospect in the 2026 class, tossed four hitless innings in their initial postseason contest—his arsenal includes a fastball with run at 86-87 mph and a slider with excellent break. Joey Shaw reached 88 mph from the left side as a freshman this year with an excellent breaking ball. The third-ranked pitcher in the 2027 class, Shaw could be a big factor as the Warriors dip into its pitching depth as it advances.

Muskego will square off against Waukesha North at 10 a.m. on Tuesday in Oconomowoc.

WAUKESHA NORTH (19-8)

Waukesha North enters Tuesday looking for its second straight upset, its first being 5-4 victory over the crosstown rival Waukesha West. To do so, the Northstars will need more production from the offense, as they averaged just 1.63 runs per game in their eight losses this season.

The top three hitters in the Northstar lineup combined for just one hit in 10 at-bats in their win over Waukesha West. Of those, INF/RHP AJ Curtis (2024; Wisconsin-La Crosse) recorded the lone hit - Curtis is a RHP/SS with a simple right-handed swing that stays through the ball with some pull-side pop. OF/LHP Cooper Haas (2025) is another bat that North will rely on to set the table in order to leave Oconomowoc with a win, in addition to being a quality relief pitcher and spot-starter for the Northstars.

Cooper Haas [2/17/24]

Curtis figures to take the ball for North, a righty with a smooth delivery, plus curveball and mid-80s fastball. The senior punched out eight across 6.1 innings of four-run ball in his previous outing against Muskego.

Waukesha North will square off against Muskego at 10 a.m. on Tuesday in Oconomowoc.

ARROWHEAD (22-5)

Arrowhead took hold of the Classic Eight after Muskego’s late-season skid, winning the conference with a victory over the Warriors to clinch the conference. The Warhawks’ postseason run will last as long as its pitching can propel them, as the team boasts a pair of top-10 pitchers in their respective classes in RHP’s Nolan Buss (2024; Kansas State) and Peter Kussow (2025; Louisville). Buss possesses a fastball that reaches 91 mph with carry and plus arm-side run. It’s paired with a swing-and-miss slider, one of the best of its kind in the state of Wisconsin. Kussow has reached 93 mph with the fastball, paired with a high-spin curveball that has a propensity for missing bats.

Nolan Buss [4/23/24]

Offensively, OF’s Issei (2024; Rose-Hulman Institute of Technology commit) and Yamato Takahashi (2025) provide much of the production for the Warhawks. Issei is a left-handed hitter with excellent bat-to-ball skills and plus speed, while Yamato hits from the right-handed side of the plate in the middle of their order. Arrowhead will need the pair to produce to advance past Sussex Hamilton.

The Warhawks will square off against Sussex Hamilton at 1 p.m. on Tuesday in Oconomowoc.

SUSSEX HAMILTON (15-12)

Sussex Hamilton pulled off a big-time upset last week as they became the first team to knock out a Power 25 team with their 5-3 win over No. 13 Menomonee Falls. The Chargers will need another gem from RHP Ben Moser (2024; St. Thomas - MN) to pull off an upset of No. 3 Arrowhead. Moser reached 90 mph this spring, also showcasing a mid-70s slider that combined for one of the most dominant arsenals in the state.

Production from their upperclassmen-heavy lineup will go a long way in providing run support for Moser. C Noah Vernon (2024; Winona State) knocked in a pair in the win against Menomonee Falls, and INF Nate Vaughan (2024; Rochester CC & Tech) added a pair of hits. Vaughan carries good bat-to-ball skills as a leadoff man whereas Vernon provides the pop in the middle of the Chargers’ order. Hamilton could become the biggest surprise team of the tournament with a second major upset.

Sussex Hamilton will square off against Arrowhead at 1 p.m. on Tuesday in Oconomowoc.

Muskego and Arrowhead enter Tuesday as two of the region’s biggest state contenders while Waukesha North and Sussex Hamilton seek to continue their underdog ways. The winners will hook up at 4 p.m. with a berth to the State Tournament on the line.
