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.
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.
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.

Pointes' Pride Instilled by Longtime Leaders

GROSSE POINTE – Neither Frank Sumbera nor Dan Griesbaum were raised in Grosse Pointe.
But no one, at least at the high school level, has done more to enhance and promote baseball in the Pointes than this long-serving pair.
Sumbera, 69, is in his 45th season as coach at Grosse Pointe North and Griesbaum, 64, is in his 34th season at Grosse Pointe South. In this sport the rivalry that exists between Grosse Pointe’s two public high schools is as good as it gets. Sumbera holds the upper hand in MHSAA Finals titles, 2-1, and Griesbaum has the edge in District titles, 23-14.
This last statistic is notable in a sense that the two programs are often paired in the same District, as they are this season. South will host North in a Division 1 District Semifinal at 10 a.m. Saturday.
This season there is an added twist to the much-anticipated community showdown. Grosse Pointe Woods University Liggett, for the first time, will compete in the Division 1 tournament lined up on the other side of the bracket from North and South. University Liggett will play Detroit East English in the other Semifinal at 11:30 a.m. The winners will play for the title approximately 2 p.m.
University Liggett won four MHSAA Finals titles the past six seasons, two in Division 4 and two in Division 3, including last season in the latter. Coach Dan Cimini, knowing he had a strong team returning, petitioned the MHSAA to opt up to Division 1 for this season and 2018.
So far the Knights have proven they can hang at the Division 1 level. They are ranked No. 2 in the latest poll released by the Michigan High School Baseball Coaches Association.
And Cimini’s group received a break in the draw as it won’t have to defeat both North and South to win the District title.
This is Cimini’s 14th season as head coach, and he tips his hat to the job Sumbera and Griesbaum have done in laying the groundwork.
“Frank has been there forever,” Cimini said. “Dan has been there a long time. I feel old, and I’m 48. I’ve coached 22 years. No doubt about it, those guys have set the standard.”
Cimini grew up in Grosse Pointe and competed in the city’s strong Little League program. He played for Griesbaum at South and played four years in college, two at Macomb College and two at University of Detroit Mercy. He was part of the 1987 South team that reached the MHSAA Semifinals for the first time in school history.
Cimini said the quality of baseball has remained strong in the community over the years but noted there have been some changes.
“The Little Leagues are phenomenal,” he said. “The Federation ball is phenomenal. But there aren’t as many kids playing. Now there are seven teams playing in the (Little League) majors. Back when I played there were 13 of 14. I miss those days. If I could take myself back, that’s where I’d go.”
At least in the modern era, one must point to Sumbera as the person most responsible for the quality of baseball being played at the high school level.
Sumbera played three sports at Chesaning High – baseball, basketball and football – and then went on to Central Michigan where he played basketball.
Upon graduation Sumbera went looking for a job and received a tip from a college roommate. Sumbera was told that Grosse Pointe High would be splitting into two schools, North and South, and that they needed teachers, and, naturally, coaches. North opened for the 1968-69 school year, and Sumbera was hired as an assistant junior varsity football coach. In 1973 he became the assistant varsity baseball coach, and the next season he took over the baseball program.
“We won the District that year,” he said. “I’ll never forget it. We beat (then Detroit, now Warren) DeLaSalle, 2-1, in the final.”
Sumbera has coached some of the best teams in the state. His 2006 Division 1 championship team was 38-1. His 1980 Class A championship team was probably his best. Five players on that team were selected in the Major League Baseball amateur draft including Bill Babcock, one of the top pitchers on that team. Babcock’s son, Luke, will enter the ninth grade next fall is expected to enroll at North and play for Sumbera.
That’s the way it is in the Pointes. This large community that borders Detroit’s eastside is infectious. It’s common for someone who grew up here to remain in the area and raise his or her own family.
“A lot of the kids I coached in the 80s, I’m coaching their sons,” Sumbera said. “They play a lot of baseball here. As they grow through the ranks to high school, (Griesbaum) and I have to make cuts. You might have 250 at the Little League level, and by the time I get them we have like eight.
“The North-South rivalry is as good as any around. I coach football, and it’s intense every year. In baseball it’s as good a rivalry as there is in the state. It’ll be the fifth time we will have played South (this season). In our last doubleheader we won the first, 12-6, and lost the second, 3-2, in eight innings. That was a crusher. It’s big. The kids know it. The families know it. They all go to church together and play against each other during the summer.”
Griesbaum, a graduate of St. Clair Shores South Lake and Central Michigan, where he played baseball, said the level of competition is remarkable especially when one considers the schools do not have open enrollment. The only way one can play for North or South is to live in the school district.
Griesbaum got his start as an assistant under Sumbera (1980-83) before going to South in 1984.
“There’s nothing like a North-South game,” he said. “Our rivalry is one of the best. It’s a baseball community. My 6-year-old grandson plays T-ball. You look at what North and South have accomplished. There’s the (Grosse Pointe) Farms and City (Little League) teams. Then there’s the success of the Redbirds that (former Detroit Tiger) Dave Bergman ran. We run a (Christmas) Holiday hitting camp. We have 75 kids the first day and 75 more the next. It’s for the second through the sixth grades. We want to expose baseball at an early age.”
Some have expressed displeasure that all three Grosse Pointe schools are in the same district. Cimini scoffs at that thought. He said there are many districts throughout the state that have more than their share of quality teams.
The last two seasons North and South were in separate Districts, and they won their respective Districts both years. In 2015, they met in a Division 1 Quarterfinal, and South won. It was the Blue Devils’ seventh trip to the Semifinals, a record (tied with Saline and Grand Ledge) for a public school in Division 1/Class A.
Cimini said he’s looking forward to seeing what his team can do against the established powers.
“I can’t wait,” Sumbera said. “The whole thing is, come June 3 you have to be ready to play.”
