DENVER – MSU Denver will pay tribute to a prolific senior class of softball players during Sunday's Senior Day celebration.
 
Outfielders Kami Grammerstorf and Shelby Robb, first baseman Miah Hartvigsen and pitcher Maddy Wilson will be honored between games of a noon doubleheader against Colorado School of Mines at the Assembly Athletic Complex.
 
The teams will also play a doubleheader at noon Monday.
 
"It is a great group of seniors, and there's no doubt that the four of them have left a mark on the program," MSU Denver coach Annie Van Wetzinga said. "They've made a huge impact individually and collectively. And all four of them have had their own unique paths."
 
Robb and Grammerstorf have been with the program for all four seasons, while Hartvigsen is in her third year with the Roadrunners and Wilson her second.
 
While Robb will be remembered as one of the greatest all-around players in program history, the others have been significant contributors as well.
 
Grammerstorf is an all-conference level player who is considered the fastest player in program history, and Hartvigsen has developed into an all-conference level player. Wilson, meanwhile, has made her way back from several years of relative inactivity to become a major contributor this season.
 
Robb set an unbelievably high standard as a freshman, batting a school-record .535 to earn All-America honors. After two more excellent seasons, she's back near the top of her game in 2024, batting .484 while ranking among the national top five with 22 doubles.
 
She's on track to have the best career batting average in program history (.430) and ranks second in hits (241), second in doubles (61), third in on-base percentage (.472), third in total bases (399), tied for third in triples (14), fourth in slugging percentage (.713), fourth in runs (163), fifth in stolen bases (53), sixth in RBIs (156) and tied for 12^th in home runs (23).
 
In addition to being an All-American on the field (and a two-time All-RMAC first team selection), Robb has also been an Academic All-American and has a 4.0 cumulative grade point average.
 
"To see her work ethic and her focus is really impressive," Van Wetzinga said. "She has high standards for herself on and off the field, on the athletic and academic side. She has shown our current and future players that we can be on the national scene, and that we can compete with anyone across the country.
 
"It's pretty hard to say that she isn't the most consistent hitter I've ever coached. And she's so dynamic because she also has great speed."
 
Speaking of speed, Grammerstorf shines in that area, where she has a program-record 86 stolen bases – including an ongoing streak of 80 in a row. But she is also a career .346 hitter who ranks second in program history with 19 triples, tied for fifth with 162 runs, 16^th with 170 hits, 17^th with a .426 on-base percentage, and 18^th with 256 total bases.
 
"I've said before that she's the fastest kid I've ever coached," Van Wetzinga said. "It's fun to actually see how impactful it can be. She's a catalyst to get things going for us. People might not understand it, but what she can do with her speed is just silly. She has such great instincts that I honestly don't tell her what to do on the bases.
 
"And off the field, she's such a good teammate. She's quiet, but she's really consistent in terms of who she is. She's someone who, behind the scenes, people can talk to her on an individual basis."
 
Hartvigsen transferred to MSU Denver after one season at Minnesota State-Moorhead, earned All-RMAC first team honors last season, and has gone to another level this year while batting .462 with seven homers and 44 RBIs. She has the 10^th-best batting average in program history (.368), ranks 13^th in on-base percentage (.441), 20^th in slugging percentage (.547) and, despite being in just her third season, ranks 20^th in RBIs (100) and 21^st in hits (154).
 
"Miah was a kid who was transferring, and we saw that she really wanted to come here," Van Wetzinga said. "We saw that she had a couple of good tools, and she was a nice kid and we gave her a roster spot. But it didn't take us long to realize that she's not just a good kid, but a great kid. She's been a huge piece of our culture as a leader and with her work ethic, and she's become a first team all-conference player who is now on a path to get even more accolades."
 
Wilson rarely pitched in three seasons at Division I Fairfield, but got into 15 games in the circle last year and in 2024 has compiled a 7-2 record with one save and a 4.49 ERA.
 
"Maddy might have had the toughest journey," Van Wetzinga said. "Any time you transfer it's a tough transition. But she stuck with it, and she never stopped working. She had an injury she had to overcome in the middle of last year, but she stayed with it, and it's been cool to see what she's done this year. She's very feisty and a fighter in the circle, and that's what we've needed."
 
MSU Denver (35-13 overall, 28-8 for third in the Rocky Mountain Athletic Conference) is looking to get back on track this weekend against Colorado School of Mines (24-18, 2014 for fifth).
 
The Roadrunners have lost five straight games, including a disappointing home sweep at the hands of Colorado Mesa that may have ended MSU Denver's realistic chances at a regular-season RMAC championship and put its NCAA Tournament hopes in jeopardy.
 
"As bad as last weekend was, we can still control a lot of things, but we've got to fight for it," Van Wetzinga said. "I've liked the energy we've had at practice. Our players aren't happy with last weekend, and they know they are better than that."
 
Despite a couple of surprising losses, Colorado School of Mines has a top pitcher in Sadriena Rodriguez and has posted two of the RMAC's more impressive wins – victories over seventh-ranked Colorado Christian in early March.
 
"They're a good team who is playing well right now," Van Wetzinga said. "Their No. 1 pitcher is very good – she can control the zone and has a good rise ball and can be tough on hitters. We have to make her work, can't be easy outs, and have to foul stuff off with two strikes.
 
"Offensively they don't have scary power – that's not their game. But they've got some lefties at the top of their order with speed who drive their offense. They are a good small-ball team that can generate runs, and if we don't take care of things defensively they can exploit us. We have to play clean and not get caught on our heels."
