EAST LANSING - Dittmer was the difference.
Grand Rapids South Christian came into Saturday's MHSAA Class B championship game ranked No. 1 and with a 26-game winning streak. But the Sailors had never faced an inside force like 6-foot-1 senior post player Allie Dittmer of Eaton Rapids.
"We tried our best to stop her," said South Christian coach Jim De Bruyn, "but she was just a horse in there."
Dittmer dominated the interior, scoring 26 points on 9 of 15 shooting and grabbing 13 rebounds to lead unheralded Eaton Rapids to its first-ever MHSAA girls basketball title in a convincing 51-38 upset of South Christian in Saturday's finale at the Breslin Center.
The Greyhounds (23-5) came into the MHSAA tournament as an honorable mention in the final Associated Press regular-season poll, but relied on five senior starters to knock off No. 6 Ypsilanti Arbor Prep in the Quarterfinals, No. 8 Flint Powers in Friday's Semifinal and then top-ranked South Christian in Saturday's Final.
"I told the girls before the game that we don't need to be perfect, we just need to be us," said 15th-year Eaton Rapids coach Willis Whitmyer. "I'm not the smartest guy here, but I'm smart enough to know when I have a good inside player. Everyone on this team has heard it 1,000 times from me: 'Get the ball inside to Allie.'"
Dittmer, who will play next year at Hillsdale College, scored two points in the first quarter as both teams struggled out of the gate. The quarter ended in a 7-7 tie.
But Dittmer came alive with nine points in the second quarter as the Greyhounds inched ahead to a 19-16 halftime lead, and it appeared that the second half would be a down-to-the-wire fight.
However, buoyed by a raucous, maroon-clad crowd chanting "We are, E.R.!," Eaton Rapids used its zone defense to stymie the Sailors' comeback attempt.
While the defense was doing its part, Dittmer got back to work on the block, scoring five points in the third quarter and then tallying 10 in the fourth (despite picking up her fourth foul with 4:35 remaining and having to sit for stretches) as the Greyhounds pulled away.
"I’ve got to give credit to my teammates; they worked it around and made it easy on me," said Dittmer, who garnered honorable mention status on the Associated Press Class B all-state team announced this week. "This win means so much to all of us.”
As Dittmer began to demand more and more attention from the Sailors, it began to open up shooting opportunities and driving lanes for the Eaton Rapids guards.
The Greyhounds were 18 of 26 from the free-throw line, compared to just 3 of 6 for South Christian. Senior guard Kathryn Mills was the only other Eaton Rapids player in double figures scoring with 11 points, including a game-clinching 3-pointer right in front of her school's delirious student section with 1:35 remaining that gave the Greyhounds an insurmountable 48-37 lead.
"It was about time, was the way I looked at it," said Mills, one of those five senior starters. "I had a rough start, but that's the way a lot of our games went this year. We got more open looks at the end because the other team is focused on stopping Allie."
South Christian 5-11 senior Renee Broekhuizen, who battled Dittmer inside all night, was the lone Sailors player in double figures, with 13 points. Broekhuizen buried back-to-back 3-pointers to pull her team to within 37-33 with 5:15 remaining in the game, but the Sailors were outscored 14-5 the rest of the way.
Dittmer scored four points during the final run, and senior guard Meghan Dassance scored five of her six during that stretch.
"She's a great player, and she has a strong body," Broekhuizen said of Dittmer. "We never gave up, we were relentless and we refused to lose. But it just wasn't our night."
South Christian (26-1) lost for the first time since last year's Semifinals at the Breslin. It was the Sailors' third appearance in a girls basketball title game, as they won the 1988 Class B championship and finished as the 1980 Class C runners-up.
Cassidy Vredevoogd blocked five shots and added six points and five rebounds for South Christian. Morgan Torres had a team-high six rebounds, and Broekhuizen added three steals.
"It's not what we planned on, but here we are," said De Bruyn, who has won 441 games in 25 years as South Christian's coach. "We struggled against their zone and couldn't seem to get many good, open shots."
The Sailors connected on just 15 of 46 shots (32.6 percent), were not able to get to the free-throw line much and were out rebounded 34-24.
Five points from Emily Reinecke and six rebounds and five assists from Bailey Baker also boosted Eaton Rapids, which placed second in the Capital Area Activities Conference Gold.
But Whitmyer felt another force during Saturday's game, especially in the second half, which he felt made a big difference in turning things in his team's favor.
"I thought our fans were unbelievable," said Whitmyer, whose team won all eight of its tournament games by at least 10 points. "I looked out there, and I thought we owned the Breslin. Our support system throughout the school and the community was really something else, and that makes this even more special."

Soccer, Hoops Next to Seed Using MPR

As the topic of seeding for MHSAA Tournaments continues to swirl in the air of numerous committee meetings on an annual basis, one of the primary concerns continues to focus on the simple question: “How?”
The MHSAA for years has been working behind the scenes on potential formulas which could best be used as a standardized tool to assist in measuring strengths of teams in a given sport.
This spring, the MHSAA introduced the Michigan Power Rating in the sport of Boys Lacrosse. The Representative Council approved limited seeding beginning in 2019-20 for girls and boys soccer and girls and boys basketball, and MPR will be the metric to determine which two teams must be seeded on opposite sides of District brackets in those sports.
“The boys lacrosse tournament has been seeded since it was added as an MHSAA-sponsored sport in 2005. The seeding is done by committee based on several criteria, one of which was statewide power rankings generated by a third-party website. In the Fall of 2018, that website ceased operation – it was the perfect opportunity for the MHSAA to develop its own data-driven, purely objective ratings system and incorporate that data into the seeding criteria,” said Cole Malatinsky, administrative assistant for the sport.
“The benefits of the new MPR system have been already mentioned – it is MHSAA controlled, simple, objective, and transparent, and it can be used by other MHSAA sports in the future.”
MPR is a computer rating formula similar to the popular RPI rating. MPR provides a way to measure a team’s strength relative to other teams, based on games played against other MHSAA tournament teams, largely on the strength of their opponents’ schedules. MPR is purely objective using only the game results listed on MHSAA.com – there is no subjective human element.
What is the basic MPR formula?
MPR is calculated using wins, losses and ties for games played between teams entered into the MHSAA tournament. The final MPR number is 25% of the team's winning percentage, plus 50% of its opponent's winning percentage, plus 25% of its opponent's opponent's winning percentage.
MPR = (.25 x W%) + (.50 x OW%) + (.25 x OOW%)
The MPR formula can be applied easily to other MHSAA team sports.
What game data is included in the formula? What game data is not?
MPR looks only at results between opponents entered into the MHSAA postseason tournament. Wins, losses and ties in multi-team shortened game tournaments (lacrosse, soccer) also count. Forfeits also are counted as wins and losses.
MPR does not use the specific scores of a game or the margin of victory in a game. The location of a game is not included in the MPR formula, and the formula weighs results at the beginning of the season the same as results at the end of the season. Scrimmages are not included.
Why use the MPR formula?
Different rating systems have been used in the past or have been recommended to the MHSAA. We wanted to have a rating system where the data was controlled and stored in house and could be used for any sport featuring head-to-head competitions.
With its own rating system the MHSAA also can control the different components of the formula, thus keeping the tenets of scholastic competition at the forefront (like not including margin of victory in the formula). Finally, by listing all scores and team schedules online, as well as showing the MPR calculator on each team schedule page, the ratings are transparent and can be replicated easily.
CALCULATING MPR
What are the detailed components of the MPR formula?
You need three numbers to calculate your MPR: winning percentage (W%), opponent’s winning percentage (OW%) and opponent’s opponent’s winning percentage (OOW%).
How do you calculate winning percentage (W%)?
Divide the number of wins by the number of total games played. A tie is worth half a win. For MPR purposes, find the winning percentage against all teams that will play in the MHSAA tournament (MPR W%). Games played against out-of-state teams, varsity “B” teams, junior varsity teams, non-school club teams, and any other non-MHSAA tournament participants should not be included when calculating winning percentage. W% should be an easy number to calculate.
How do you calculate opponent’s winning percentage (OW%)?
Average the winning percentages of a team's opponents. When calculating the winning percentage of a specific opponent, use the opponents "Adjusted Winning Percentage" (ADJ W%). Adjusted winning percentage eliminates all games the team played against that opponent (as well as its games against non-MHSAA opponents).
For instance, if the team beat an opponent with an overall record of 4-1, use a record of 4-0 (1.000) for that opponent. If the team lost to an opponent, use a record of 3-1 (.750). Find the ADJ W% for all opponents, and then take the average. If a team plays an opponent team twice, that opponent’s ADJ W% will be counted twice.
OW% is not calculated via the combined record of the opponents; instead take the average of all opponent’s winning percentages.
How do you calculate opponent’s opponent’s winning percentage (OOW%)?
Use the same process described above, except calculated for the opponents of a team's opponents. This number is much harder to manually calculate, so the OW% for every team is listed on the MPR page of the MHSAA website.
Again, simply take the average of all opponent’s OW%.
How often is MPR calculated?
MPR is calculated about every five minutes. Enter a score and a minutes later the team MPR and the MPR of all the team's opponents will update.
How much will my MPR change throughout the season?
You will see wild MPR swings in the beginning of the season, but after about 10 games played your MPR will start to level out. At 20 games played you will see very little movement with each additional game played.
My score is missing. How can it be added?
This is a crowd-sourced system. Any registered user of MHSAA.com can add a missing score. ADs, coaches, parents, students and fans all can login and enter a score for any game.
What are some common errors when calculating MPR?
When calculating your team’s winning percentage, only include games against MHSAA-tournament teams. When calculating your opponent’s winning percentage, don’t include the games they played against you. When calculating ties, count the game as a half-win and half-loss.
What happens if a game is cancelled?
Because the MPR system works off of averages, it will not make a difference in the final MPR if a game cannot be rescheduled. It would not penalize, nor benefit, any team involved in that scenario.
USING THE WEBSITE
Where can I find game scores?
A list of statewide scores for all sports can be found in the MHSAA Score Center. To find a schedule for any team click on “Schools & Schedules” in the top navigation bar, search for the school, then once on the school page click the sport. You can also see a list of all schools (with links to schedules), on the statewide MPR list.
“We continue to have great success in score reporting for varsity boys lacrosse contests. While we state that schedule submission and score reporting to MHSAA.com are required, athletic directors and coaches understand that in order for MPR data to be accurate, we need consistent and accurate score reporting,” said Malatinsky. “MHSAA.com is now the primary site for high school boys lacrosse schedules, results and ratings in the state.”
How should I use the statewide list of teams and MPR?
Linked to the boys soccer page (and eventually to be added for both basketball pages and girls soccer) is a statewide listing of all Michigan Power Ratings (MPR) for teams entered into the MHSAA postseason tournament for that sport. Linked on the MPR page is an explanation of the District draw formula, describing when and how teams will be placed on the bracket.
The MPR data updates every five minutes. Click on the column headings to sort the data. You also can use the drop-down menu to show teams in one Division, or type a District number in the box to filter teams for that District (Region for boys lacrosse).
You also can click on any school name to go to its schedule page.
How do I read the school schedule page?
The schedule at the top of the page shows the date and opponent for all scheduled games, and results for games already played. If results are missing, click “Submit Score” to add a game score.
Below the game schedule is the MPR Calculator. The calculator is split into three sections. The first section shows the three MPR component scores for the team, as well as the team’s current MPR score. The second section shows the MPR information for the team’s opponents – specifically, for the opponents the team already has played (actually, for games where scores have been submitted). Only these games are included in the MPR calculation.
The third section highlights future opponents. The MPR data for future opponents are not used in the MPR calculation for the team.
