Crosby completed a perfect season last weekend 30-0, with his final four wins at the Lower Peninsula Division 2 Finals earning him the championship at No. 1 singles. Top-seeded in the bracket, he clinched with a 6-1, 6-2 victory over Birmingham Seaholm’s second-seeded Carter Griffith. 

This was Crosby’s third appearance in a championship match at the Finals; he finished No. 2 singles runner-up as a freshman and No. 1 singles runner-up as a junior. Crosby’s only losses those seasons came in those title-deciding matches, and his sophomore-year Finals ended with a first-round defeat against Griffith. Crosby finished with a four-year singles record of 123-5 – with those wins ranking 13th on the MHSAA career list – and claimed 19 victories this fall by 6-0, 6-0 scores. He also plays basketball for South Lyon East, and he’s hoping to continue his tennis career at the collegiate level. His brother Cameron plays at Kalamazoo College.

SAC Sound-off: Familiar Opponent

May 16, 2012

Pontiac Notre Dame Prep and Walled Lake Central were two of 48 softball teams that played in this season's Michigan Stars Tournament two weekends ago in Grand Blanc. Often, athletes know little about those they are facing on the opposing bench. But a final game at this year's tournament gave two MHSAA Student Advisory Council members -- Walled Lake Central junior Taylor Krumm and Notre Dame Prep junior Carly Joseph -- an opportunity for friendly competition.

Below, Joseph tells us the story from her side of the diamond.

At this year’s Michigan Stars Tournament, I had a fun and unique experience: I got to play against one of my good friends, (and fellow MHSAA Student Advisory Council member) Taylor Krumm.

Taking the field against Walled Lake Central, I was excited to see a familiar face on the other side of the field.  My team, Notre Dame Prep, was warming up for our fifth and final game of the weekend, and we were more than a little tired.

For me, knowing that I would be playing not just against Walled Lake Central, but against my friend Taylor, gave me extra motivation to play hard.

As a pitcher, one of the reasons I like to play softball is the mental game. Usually, I am just pitching against another nameless batter from the other team. But that day, it was different. Taylor hit in the lead-off spot for Walled Lake, so she was the first batter I faced. Immediately, the competition was on. I was eager to strike her out; she wanted to get a hit. We both made great plays and also made some mistakes throughout the game. In the end, I wasn’t going to win the game by myself and neither was she. Even though I had some extra motivation to pull off a win, I needed to make sure that I translated that energy to my teammates.

Playing against Taylor made that game more exciting, and also put softball in general back in perspective.  I knew that Taylor and I would still be friends no matter who won, which relieved some of the pressure to win and reminded me that I play softball simply because it’s fun.
