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: Now we're the seniors

June 21, 2012

For our final MHSAA Student Advisory Council Sound-off of the 2011-12 school year, we asked our juniors -- now seniors-to-be -- what they are looking forward to most in 2012-13.

Like students all over the state, our SAC members also are enjoying summer break. But check back this fall for more peer perspectives from our 16 seniors and juniors.

I'm most looking forward to ...

"... being a leader in the classroom, a leader on the court and having underclassmen look up to me for support." -- Elle Lehman, Portland St. Patrick

"... just enjoying my final year of high school sports, and also trying to figure out where I want to go to college. I also really am excited about being a leader on my teams." -- Taylor Krumm, Walled Lake Central

"... to being Big Man on Campus." -- Thye Fischman, Vandercook Lake

"... my senior golf season and our run at a state championship." -- Abby Radomsky, Kalamazoo Hackett Catholic Central

"... meeting the new juniors," -- Evan Lamb, Rogers City

"... taking a bigger leadership role on my cross country team and enjoying my last year of high school sports." -- Carly Joseph, Pontiac Notre Dame Prep
