Similarities Tie Slugging Pair's 1991 Pursuit of .600 Average, Paths After

They both remember chasing the identical goal 33 years ago.

It wasn't so much that Hastings' Nick Williams and Dwain Koscielniak of Gaylord St. Mary were aware in 1991 of becoming the first MHSAA-recognized .600 hitters in state history. What the two remember most about their magical final high school seasons has little to do with records, but simply closing out outstanding baseball careers with a bang.

"I think it was the same scenario for both of us," Williams said. "You just want to get a hit, drive the ball every time you're up."

It may be forgotten now, but in an era where tracking batting averages wasn't as simple as inserting a thumb drive and a couple clicks on a laptop, it's easy to see how the one-of-a-kind hitting exploits of Williams and Koscielniak may be overlooked. For instance, with just days left in their senior seasons neither knew they were closing in on the state record for batting average of .577 by Greg Atkinson of Maple City Glen Lake in 1985. The two were more focused on helping their teams win District titles and then beginning their summers.

About all the pair really knew was that magical seasons were about to end. Both were batting over .600, but when ballplayers are hitting that well, there's a fine line in maintaining such rare territory. As both found out – one painfully so and the other happily – every at-bat is critical. Koscielniak wound up slugging a pair of homers in his final game to finish with a .629 mark while Williams, who started the last day of his senior season with a hefty .612 mark, went hitless for the first time all spring to finish at 591.

While the chase to hit .600 is obviously an entertaining story, it's only the tip of the iceberg in terms of the amazing parallels between the lives of Koscielniak and Williams, who lived 170 miles apart growing up in Gaylord and Hastings, respectively.

Both, for example, were outstanding dual-sport athletes. Koscielniak graduated second on the Michigan football career rushing list with 5,078 yards from 1987-90, and he still owns the state single-game record of 529 yards against Pellston on Oct. 26, 1990. Williams, meanwhile, averaged 24 points per game as a senior in basketball and could have been a dual-sport athlete at the next level if not for sticking with baseball.

In addition, both went on to stellar collegiate careers. Williams was a second-team all-Mid-American Conference selection in 1995 as a junior, and Central Michigan University captain as a senior. Koscielniak played two years at Mott Community College before becoming a slugging catcher/infielder at Ferris State. He was named Player of the Year in the Great Lakes Intercollegiate Athletic Conference in 1994 when he won the league’s triple crown hitting .403 with nine home runs and 37 RBIs.

They continue to rank among the elite on the MHSAA record book list for top batting averages for a single season. Both had flirtations with pro ball as Williams was taken by the Seattle Mariners in the 48th round of the 1991 MLB draft and later drew interest from Boston and Cincinnati following his time at CMU. Koscielniak was drafted by San Diego in the 32nd round in 1994 and reached High-A a year later. He batted .261 with 32 RBIs in 64 games over two minor league seasons.

Koscielniak and Williams, who unknowingly played against each other with their college teams in 1994, also both wound up in athletics after college. Williams became an associate athletic director at Central Michigan, while Koscielniak coached baseball at Gaylord St. Mary.

There's more as both players are fathers of college-level talents. Williams' daughter Jayden ran track at Central Michigan while another daughter, Taryn, is playing volleyball at Delta College. Koscielniak's sons Steven and Christopher both played baseball at Delta College, daughter Brooke is an equestrian at Saginaw Valley State, and youngest son Brett is a three-sport athlete at Gaylord St. Mary.

If there's one more nugget which Williams and Koscielniak have in common, it’s that both credit long hours of work for becoming outstanding hitters. Williams would use a tarp in the family garage for a makeshift hitting cage, while Koscielniak's offseason hitting quarters was a cage stuck away in a pole barn. Both said they would never have approached being .600 hitters without putting in loads of extra time.

"I got my swings in several times a week in the offseason, and that really helped me," said Koscielniak, whose professional career received its earliest spark when a Ferris State science teacher/part-time MLB scout wandered past the school's gymnasium and noticed Koscielniak practicing throws to second base from his spot as catcher during winter workouts.

Williams remembers getting in about 200 at-bats with summer travel teams in Hastings, Grand Rapids and Battle Creek between his junior and senior years.

"I had a lot of success as a hitter because I put the time in," said Williams, who remembers half a dozen scouts at every Saxons game as a senior. "I didn't play a fall sport, and I put in a lot of time just hitting. I became aware of being able to hit the ball the other way, and I think my confidence began to grow."

As for approaching the .600 mark during their final seasons, Williams and Koscielniak said they were blissfully unaware of any state batting records. Williams does recall never considering trying to preserve a .600 average by taking a game off down the stretch.

"No, I never (had) a thought of that – not even a conversation," he said. "A lot of time has passed since then, but I don't remember sitting out at all. No way. I was always going to play, and that's it."

Koscielniak also doesn't recall worrying about hitting 600. While Koscielniak was the first .600 hitter in state history, only 17 others have gone on to become MHSAA-recognized .600 batters. Dan Taylor of Kingsley holds the state record for highest average with a .688 mark in 2007.

Koscielniak also hit 17 home runs as a senior and finished his career with 35, which continues to rank eighth on that statewide all-time list.

"Back then if you loved the game, you just played. How it turned out for me is how it turned out," he said. "I was competitive and played hard. I played well at Mott and then Ferris State, and the door opened up for me a little."

Williams and Koscielniak remember one huge drawback in trying to hit .600: walks. Pitchers would simply not give them anything to hit. Williams remembers a doubleheader against Coldwater where he hit home runs in his first at-bats in both games, then received two intentional walks in both games. Koscielniak's two homers in his final game were followed by two intentional walks.

Such a stingy pitching philosophy was par for the course, they say.

"That becomes very difficult for a hitter," Williams said. "You have to be dialed in when you get your opportunities. It was a fun year for me, but a struggle at times because (the walks) make you feel like you're not doing your job for the team.

"I don't think hitting .600 was a big deal. We didn't talk about stats and those things. You keep track a little, but I had no idea till the end of the year. And in the end, it's not about stats. I loved playing baseball."

These days, Williams is an instructor as part of the physical education and sport faculty at CMU, teaching courses on professional and collegiate athletics. Koscielniak is an operation manager for Schwan’s Food Service and with his wife Liz owns the Gaylord Equestrian Center.

St. Mary's Standouts, More Michigan Stars Taking Major Steps in Pro Baseball Climb

It took former Orchard Lake St. Mary's star Brock Porter three years to reach five professional baseball victories on the mound.

It's taken only four months for Porter to win five more.

Porter is one of four Eaglets from the 2019-22 MHSAA Finals champion clubs now navigating their way through professional baseball. The 2022 Mr. Baseball Award winner, now a 23-year-old right-handed pitcher, went a combined 30-0 with an ERA under a run per game for those three championship teams (with 2020 was canceled due to COVID-19) before being tabbed by the Texas Rangers in the fourth round of the 2022 MLB draft.

Injuries slowed his first three minor league seasons, and Porter didn't win any games over his first two in the Rangers chain. But a healthy Porter has taken significant steps forward this season with the High-A Hub City Spartanburgers (S.C.) with a 5-2 record, 3.56 ERA and 52 strikeouts over 43 innings and 13 games. Porter was actually 0-9 over his first two minor league seasons before going 5-1 a year ago with Hickory of the Class A Carolina League.

He said he doesn't feel rushed in moving up the Rangers minor league ladder.

"I still have time," he said. "The big goal for me is I want to move up throughout the chain. Things are going very well, I'm excited for the season. Health-wise, I feel very good. I still want to grow into the dominant pitcher I was in high school."

Porter's role within the organization has changed. While he started 28 games over first two seasons, Porter has transitioned to the bullpen, where he's pitched in a combined 54 games during last two summers.

His former Eaglets teammates also are winding their ways through the minors.

Ike Irish runs the bases for the Frederick Keys. Among them, Ike Irish was one of two former Michigan high school baseball stars who played in Sunday's prestigious MLB Futures Games as part of the all-star festivities in Philadelphia. Irish, a first-round pick a year ago, has emerged as Baltimore's No. 2 prospect as ranked by MLB.com. He went 0-for-1 with a walk after starting the game as his team’s designated hitter. The other past Michigan prep star playing Sunday was Okemos’ Caleb Bonemer, a top prospect in the Chicago White Sox chain. He went 0-for-2 as the starting third baseman for the American League.

Irish, an outfielder who also can catch, has dominated High-A Frederick (Md.) with 12 homers, 15 doubles, 47 RBIs and 18 stolen bases while batting .264. Irish hit .230 in 20 games with Low-A Delarva (Md.) in 2025 after batting .350 with 39 homers over three years at Auburn University, where he was named an All-American as a junior.

Irish, who batted .427 and .450 with a combined 19 homers and 95 RBIs during his two seasons at St. Mary's, said his professional goals don't include obsessing over posting numbers.

"No, I just want to go out there and play," he said. "I don't care about numbers or hitting X number of homers. I would rather just go out and play."

In addition to Porter and Irish, former St. Mary's star Nolan Schubart has heated up at high-Class A Lake County (Ohio) of the Midwest League. A Cleveland Guardians prospect, Schubart was named last Monday as the league's Player of the Week after hitting three homers with 12 RBIs and 20 total bases. The former third-round draft pick is now batting .248 with 67 RBIs in 69 games with a 37-game on-base streak.

The fourth former St. Mary's player in the minors is infielder Alex Mooney, the 2021 Mr. Baseball Award winner. Mooney is batting .203 with 36 RBIs and 18 stolen bases in 22 attempts with Double-A Akron (Ohio). Mooney was taken by the Guardians in the seventh round of the 2023 draft out of Duke. He started his professional career as a shortstop, but has branched out to playing 27 games at second base and 17 at third this season.

Mooney said playing at the Double-A level has been an adjustment.

"It's a tough place," he said. "I'm not really a huge stats person; I just take it day-by-day. When you're playing 140 games a year in the minors you just try to get better every day. That's the mindset. You just try to get better and win the battle in the war."

A fifth member of the 2021-22 Orchard Lake St. Mary's teams will have a shot at professional baseball. Former Eaglets pitcher Nolan Higgins was taken by the Toronto Blue Jays in the fifth round of Sunday's MLB draft.

Caleb Bonemer takes the field for the Birmingham Barons.Meanwhile, Okemos’ Bonemer has been in the national spotlight twice over the first four months of this minor league season. A member of the coaches association all-state Dream Team as a high school senior in 2024, he gained a painful national notice May 5. The New York Yankees' all-star pitcher Gerrit Cole, while rehabilitating from an injury with Hudson Valley (N.Y.), surrendered a homer and single during Bonemer’s first two at bats, then drilled the Chicago White Sox prospect with a 97-mph fastball to the shoulder. The move incensed White Sox fans, who believed Cole was trying to send Bonemer a message after banging out the two hits.

Bonemer not only survived, but has thrived. He hit .238 with High-Class A Winston-Salem (N.C.) to start this season, but slammed 18 homers and 15 doubles along while totaling 43 RBIs and 10 stolen bases. That earned him a promotion to Double-A Birmingham (Ala.) where he's off to fast start with a .279 average, three homers and 11 RBIs over his first 17 games.

Four other former Michigan prep stars have had active professional seasons. Outfielder Dante Nori, who helped Northville to the 2024 MHSAA Division 1 championship, has built on his rapid start this spring when he batted .400 for Italy in March's World Baseball Classic. A member of the all-state Dream Team as a senior at Northville, Nori is batting .245 at Double-A Reading (Pa.) in the pitching-heavy Eastern League. Nori has 12 stolen bases and 11 doubles.

Former Saginaw Swan Valley infielder Mitch Jebb has played in 20 games at Double-A Altoona (Pa.) and Triple-A Indianapolis in the Pittsburgh Pirates’ system, batting .273 with eight RBIs. A 2018 all-stater at Swan Valley, this is Jebb's fourth season in the minors after batting .327 in 147 career games at Michigan State.

Howell native and the state's 2017 Mr. Baseball, Sam Weatherly, is playing his fifth year of professional baseball. Weatherly is 1-3 in 23 games at Double-A Hartford (Conn.) of the Eastern League, a Colorado Rockies affiliate. He's struck out 34 batters in 28 innings.

Jeff Criswell from Portage Central is still recovering from Tommy John surgery a year ago. A member of the 2019 NCAA runner-up Michigan club, Criswell was called up to the Rockies for two games during the second week of June. He's divided time between three levels this season, with a 2-1 record and 6.86 ERA over 19 games and 29 strikeouts in 21 innings. In 2025, he pitched in 13 games for the Rockies with a 2.75 ERA before the surgery.
