Originally, Deanna Radcliffe got into coaching lacrosse simply because it was a nice summer job.
From that simple beginning, Radcliffe is now on the verge of making high school sports history within the state of Michigan.
No girls or boys lacrosse coach has reached 300 career victories since the sport became MHSAA-sponsored in 2005. But Radcliffe is oh-so-close. Following a win over Haslett on Wednesday, Radcliffe has 299 career victories.
The milestone 300th win likely will come Saturday when South Lyon United plays in a tournament at Saline.
In order to get their names etched in the record book, any high school coach in Michigan has had to reach at least 300 wins since the MHSAA brought the sport into its championship lineup. So Radcliffe is literally about to become the first and only coach in the MHSAA coaching records for lacrosse.
Radcliffe is in her 10th season coaching for South Lyon Unified and also coached at Hartland from 2013 to 2022. This is actually her second stint at South Lyon, where she spent seven years as head coach before taking the Hartland job.
“It just means I’ve been doing this for a long time,” Radcliffe said. “What it really represents to me is all the players, coaches and families I’ve had the opportunity to coach. I’ve been fortunate to coach in an area that was willing to embrace the sport. I have been able to catch some really great teams and athletes across all levels from youth to high school and even collegiately. That’s the part that means the most, those relationships and experiences. The wins are just a byproduct of that.”
Radcliffe got her start in lacrosse very young, saying she picked up the game at 3-4 years old while growing up in Pennsylvania. She was introduced to the game by her aunt.
“It just became part of my life early on,” she said.
Radcliffe eventually became good enough as a player to earn a college opportunity, ultimately being named the Atlantic 10 Offensive Player of the Year in 2003 while playing for Temple.
Radcliffe eventually started a career as a special education teacher and was a high school coach in Pennsylvania before moving to Michigan in 2006, where she has coached club, high school and even college lacrosse as she spent time as an assistant at Cleary University.
“I just enjoyed being around the game and the competitive environment, so I kept doing it,” Radcliffe said of what has kept her coaching. “Over time, it stopped being something I was just doing in the summers and became something I really valued and stayed connected to. It’s grown naturally from there, and I’ve been fortunate to continue coaching while also working in education.”
The most noteworthy win of her career came last June, when South Lyon Unified earned a 6-3 Division 1-clinching victory over Hartland to give Radcliffe her first MHSAA Finals championship as head coach in a matchup between the two programs she built up.
South Lyon Unified is 18-0 this season and has won 39 straight games going back to last spring's opener.
“She has so much knowledge of the sport and really cares for each and every one of us,” said South Lyon United senior captain Teagan Wesner. “Deanna has been one of the best coaches I have ever had, and I am extremely grateful to have had the opportunity to play for her. I am very happy for Deanna, and I am excited to be a part of the team who helped her reach 300 wins.”
When Radcliffe first arrived in Michigan, lacrosse was in its first years as a sanctioned sport by the MHSAA. Now, she has seen it grow by leaps and bounds.
“One of the most rewarding parts has been seeing the long-term impact,” she said. “Many of the players I once coached are now youth, high school or college coaches themselves. Some are officials, and some I’m even coaching against or alongside now. That’s been incredibly meaningful and really speaks to the strength of the community the sport has built.”

Super Scorer Marosi, Grand Rapids Catholic Central Complete Perfect Run

ANN ARBOR — As the final minutes dwindled to seconds, Joe Curcuru was content knowing No. 22 possessed the ball.
It was fitting that Claire Marosi had the ball last as the clock struck zero and the celebration was on for the Grand Rapids Catholic Central girls lacrosse team, which completed an undefeated season by beating defending Division 2 champion Detroit Country Day 10-9 in the Final at University of Michigan Lacrosse Stadium.
Marosi, a senior, added two massive fourth-quarter goals to the 152 she already had scored this year as the Cougars completed a 23-0 season and collected their second Finals trophy and first since 2011.
But after defeating Country Day twice this season by 17-7 and 20-7 scores, the Cougars needed just about every second to fend off the Yellowjackets. And that was no surprise to Curcuru.
“They’re a terrific team. To be the best, you have to beat the best. And they’re the defending state champ. We knew it would be a battle back and forth,” said Curcuru, who had led Grand Rapids Forest Hills Northern/Eastern to Division 1 runner-up finishes the last two seasons before making the move to Catholic Central.
Hadley Keating opened the scoring for Country Day just 14 seconds into the game, followed swiftly by a Sarah Rott answer 11 seconds later that tied the game at 1-1. Catholic Central poured in four more first-quarter goals — two each from Cate Marshall and Mairin Ziegler — to sit ahead 5-1.
“I think we started a little bit slow, and that kind of got us on our heels,” said Country Day coach Liz Nussbaum, whose team finished 17-4-1 with three losses to Catholic Central. “But I’m so proud of how our team was able to push back and not let a couple runs get us down.”
Mary Pavlou scored the first of her three goals for Country Day in the second quarter, and after Rott re-established a four-goal cushion for the Cougars, Olivia Winowich and Emma Arico pulled the Yellowjackets to within 6-4 inside of two minutes to play in the first half. Marshall’s third goal of the game gave the Cougars a 7-4 halftime lead.
The third quarter was all Country Day as Arico added two more scores and Pavlou had her second of the game to pull Country Day even entering the fourth. Country Day outshot Catholic Central 21-7 over the middle two quarters, including 10-2 during the third.
Keating gave Country Day an 8-7 lead 1:34 into the fourth, and that seemed to ignite Marosi and the Cougars. Curcuru moved her to the draw circle, and Marosi responded with back-to-back goals 1:15 apart to restore her team’s lead.
“I think it was a game of swings,” Marosi said. “(Country Day) had the momentum, then we had the momentum. Just to finish with momentum on our side was really helpful. I think we all knew when it comes down to it, we would pull it off.”
Rott scored what proved to be the game-winner midway through the fourth quarter, but Country Day was not done, pulling within one on Pavlou’s goal with 4:17 to play. Catholic Central goalie Samaya Dean, who finished with 10 saves, made a massive one with less than two minutes to play by turning away what would’ve been the game-tying goal.
That’s about the time Marosi took control of the ball, drawing two penalties inside the final minute while playing keep-away and bleeding the clock.
“I told her after the game, there is nobody else in the state of Michigan I want with that ball than her,” Curcuru said. “It felt long, but it also felt good because I knew 22 had it for us.
“Claire not only is an incredible athlete, she’s so competitive and such a great leader. To have someone who can say, ‘When things are going tough, jump on my back. I’ll carry you a little bit.’ And that’s what Claire does for us every single day. And you saw it today. When we needed her the most, she came up the biggest.”
Marosi is heading to Northwestern University to play lacrosse after finishing with the third-most goals all-time for a single season with 154.
Catholic Central’s 10 goals were its fewest of the season and came after the Cougars outscored their first four postseason opponents by a combined 85-23. Nussbaum credited her team’s defense and the play of goalie Campbell Lindner for limiting the Cougars’ potent offense.
“Campbell really stepped up in the net. I‘m really proud of how she was able to make some of those key saves in those key moments,” Nussbaum said. “We definitely made tweaks (from the previous two games against Catholic Central), but at the end of the day I believe in the quality of our athletes.”
