Pitch Perfect
August 5, 2016
The national rules of high school baseball for the 2017 season will require for the first time that state high school associations adopt policies and procedures that limit the number of pitches that an individual player may make over a specified number of days.
Presently, Michigan High School Athletic Association rules state that a student may not pitch more than three consecutive days regardless of the outs pitched, and shall not pitch for two calendar days following that in which the player pitched his 30th out.
In the past, there has not been consensus among Michigan high school baseball coaches or support by the MHSAA Baseball/Softball Committee to impose a specific pitch count; and the new national rule does not prescribe what the maximum count should be or how it should be applied.
The MHSAA will convene a group of coaches and administrators this month to discuss the many questions created by the nebulous national mandate. The group’s challenge is to craft a rule that will not result in students pitching more than they do under the current rule, especially at earlier grade levels, and a rule that is as simple to monitor and manage as the current rule.
The proposal of this study group will be reviewed by baseball coaches and school administrators throughout Michigan before submission for action by the Representative Council in December.
Michigan’s climate and culture within high school baseball probably makes a change in the MHSAA pitching rule unnecessary for the high school season. And sadly, any change made for high school play is likely to have little or no effect on the summer and fall ball that may be much more damaging to young arms than the high school season which often is much more restrained in the number of games per day and per season than non-school baseball.
We can hope, of course, that the additional focus on pitching risks at the high school level will be seen and taken seriously outside the high school season.
Jenison Rolling Through Hot Streak, Rising in Rankings as Playoffs Approach

JENISON – During the earliest beginnings of this season, Jenison baseball coach Chris Ter Vree noticed certain aspects of his team were lacking.
Although overflowing with talent and buoyed by the return of five key seniors from last year’s 32-win team, improvements would be needed in order for the Wildcats to achieve their desired success.
“We've made some huge strides as a group,” Ter Vree said. “We knew this was going to be a very talented group, but once we got into the early part of the season we saw some areas that we had to get better at and we got a lot better at them.
“That has allowed us to be successful. It’s watching them interact like they do and it's watching them fight back down four runs to a very good Byron Center team (Monday night) and not give up.”
The Wildcats (24-5-1) have emerged as one of the hottest teams in the state, as evident by their winning 14 of their last 15 games and jumping up to No. 6 in the Division 1 rankings.
They clinched at least a share of the Ottawa-Kent Conference Green title Monday by defeating No. 16 Byron Center 4-0 in the first game of the doubleheader. The conference crown is Jenison’s first since winning the O-K Black seven years ago.
“It's just an exceptional group of guys who enjoy playing the game of baseball with each other,” Ter Vree said. “And just being a coach of a group of guys like this is so much fun and so enjoyable. Just to watch them enjoy the game.”
A superb pitching staff, led by senior Case Bosch, has helped the Wildcats keep opposing teams in check. The 6-foot-5 lefthander has committed to Coastal Carolina.
“He’s fun to watch on the mound, and I’ve coached him for four years so it’s sad to think this journey with him is almost done,” Ter Vree said. “His composure is fantastic, and you can’t rattle him. He throws so many pitches for strikes, and he is a smart guy. He calls his own pitches and we don’t allow a lot of people to do that. We are very fortunate to have, I think, the best pitcher in the state on our staff.”
Junior hurler Ethan Lenzo has exceeded expectations and has been one of the “biggest surprises” on the team, according to Ter Vree. The pitching staff also includes seniors AJ Park, Ben Slagter and Braydon Hilaski, and juniors Parker Felgner and Kelson Swainston.
Junior Pierce Ginzer also has pitched and batted well since coming back from a hamstring injury.
“We have a lot of guys who have done a really good job of coming in and pounding the strike zone,” Ter Vree said. “We are very fortunate to have a very strong pitching group, and we’re thankful for that.
“We’ve also been really good at the plate. Up and down the lineup, we just have a really solid group of guys.”
Park, a Davenport commit who has delivered timely hitting, believed this year’s team could be special.
“We had our five seniors returning, and we had the expectation of being a winning program,” Park said. “We had a lot of juniors coming up who we knew had talent, and we hoped that they could carry it on and play the roles they had, and it’s been going well.
“Pitching has been strong for us, and I think over the last three weeks we’ve really picked it up and been playing some pretty good ball. We've been hitting the ball a lot more consistently up and down our lineup, and that has helped out a lot.”
The Wildcats have been especially dominant on the road, winning six in a row.
“We love playing at home, but it doesn’t faze our guys at all when we go on the road,” Ter Vree said. “We like to have the other crowd be a little loud, and we also like to show people what we are capable of. We like being challenged by that.”
Ter Vree said he had shied away from setting goals for this season, but would like nothing better than to win the conference outright.
A victory in either a resumed game against Byron Center on Thursday (currently tied 4-4 in the seventh inning after a late Jenison rally) or the following meeting will give the Wildcats the title outright.
“One thing we’ve gone away from is setting up goals, just because sometimes it's good to do and sometimes not good to do,” Ter Vree said. “But Monday night winning that first game did give us the opportunity to check off one of those boxes that we talked about at the beginning of the year. We knew this was going to be a good conference to be a part of, and we knew Byron Center was probably going to be the team that was returning a lot of starters and coached extremely well.
“We knew it would come down to that last series and it was good to get that first one out of the way knowing that no matter what happens these next two games, we have a share of the O-K Green. We’re happy about that, but we don’t like sharing things so we're definitely looking to win one of the next two games so this can be ours because this group of guys definitely deserves it.”
Jenison begins the postseason next week against Holland West Ottawa. And while the team hopes to make a deep run, Ter Vree said the outcome won’t define the season.
“We want to win a District title and make a run, but it’s not going to make or break the season,” Ter Vree said. “We’re just trying to continue to have a great season, but it’s not going to write the story of this team. They’ve already written their story, and I’m just proud to be a part of it.”
The Wildcats suffered a disappointing 1-0 loss to Hudsonville in last year’s District Final, and a potential rematch against the Eagles is expected.
“I think we’re ready (for the playoffs),” Park said. “We know who we’re playing, and we’re looking to play them (Hudsonville) in the Finals. Last year we lost 1-0, but we’re coming back to see what we can do.”
