South Lyon United's Radcliffe Approaching Milestone Win, Another History-Making Moment

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.”

Lacrosse Finals Move to U-M Among Headlines as Spring Sports Ramp Up

The Girls & Boys Lacrosse Finals will be played at University of Michigan Lacrosse Stadium for the first time, one of the most notable changes for this season as sports ramp up for more than 100,000 athletes anticipated to participate this spring for Michigan High School Athletic Association member schools.
The MHSAA sponsors postseason competition each spring in baseball, girls and boys lacrosse, girls soccer, softball, girls and boys track & field, boys golf (Lower and Upper Peninsula) and girls golf (UP), and girls (LP) and boys (UP) tennis.
The U-M Lacrosse Stadium opened for competition in 2018 and seats 2,000 spectators. The Girls Lacrosse Finals will be played Friday, June 7, with Division 1 at 4 p.m. and Division 2 at 7 p.m. The Boys Lacrosse Finals will be played the following day, June 8, with Division 2 at 11 a.m. and Division 1 at 2 p.m.
Girls lacrosse also has a significant format adjustment this season, as games will be played with four 12-minutes quarters instead of the previous two halves, in part to allow coaches more opportunities to provide direct instruction during a game. Two more rules changes are expected to improve flow of play – players awarded a free position outside of the critical scoring area no longer must come to a stop and settled stance before self-starting, and false start penalties outside the critical scoring area have been eliminated.
Several more rules changes will be noticeable this spring:
In boys lacrosse, a change was made to enhance player safety. Play will stop immediately any time a player’s helmet comes off, and that player may not return until the next dead ball after play continues.
Fair and legal starts are a continued emphasis for track & field, and a rule change will allow for movement before the start of the race as long as a competitor does not leave their mark with a hand or a foot after the “set” command, or make forward motion before the starting device is activated.
A significant rule change in softball alters pitch delivery mechanics. The pitcher may now have both feet off the ground at the same time when releasing the ball as long as both feet remain within the 24-inch width of a pitching plate and the pitcher does not replant the pivot foot before delivering the pitch.
Another change in softball requires that a playbook/playcard be worn on the wrist or kept in a back pocket to reduce distractions. If worn by the pitcher, the equipment must be worn on the non-pitching arm. Similarly in baseball, a wristband with plays or instructions will be permitted but must be a single, solid color, and for pitchers may not contain the colors white or gray or be otherwise distracting. Baseball players must wear this wristband on the wrist or forearm, and pitchers may wear one only on their non-pitching arm.
Also in baseball, a rule change allows for one-way communication devices worn by the catcher to receive instructions from the dugout while on defense, for the purpose of calling pitches. The coach must be inside the dugout/bench area to use the communication device.
Golfers now are required to participate in at least four competitions for the high school team prior to representing that school team in an MHSAA Regional or Final. Those four regular-season competitions may be 9 or 18-hole events.
In tennis, for the first time in Lower Peninsula play, a No. 1 doubles flight from a non-qualifying team will be able to advance from its Regional to Finals competition. To do so, that No. 1 doubles flight must finish first or second at its Regional, and the No. 1 singles player from that team also must have qualified for the Finals individually by finishing first or second in Regional play.
On the soccer pitch, two officiating-related changes will be especially noticeable. Officials now may stop the clock to check on an injured player without that player being required to leave the match – previously that player would have to sub out. Also, categories for fouls have been redefined: careless (which is a foul but does not receive a card), reckless (a foul with a yellow card) and excessive force (foul with red card).
The 2023-24 Spring campaign culminates with postseason tournaments, as the championship schedule begins with the Upper Peninsula Girls & Boys Golf and Boys Tennis Finals during the week of May 27 and wraps up with Girls Soccer, Baseball and Softball Finals on June 15.
