Performance of the Week: South Lyon East's Mason Crosby
October 30, 2026
Mason Crosby ♦ South Lyon East
Senior ♦ Tennis
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.

Friendly Competition
May 16, 2012
When Walled Lake Central junior Taylor Krumm dove for third base during her final game of the Michigan Stars Tournament two weekends ago, an opposing fielder stood in front of the bag, hoping to tag her out.
But it wasn't a stranger in that green and white uniform; it was a friend.
Krumm and Pontiac Notre Dame Prep's Carly Joseph are members of the MHSAA Student Advisory Council. On this day, they also were softball opponents -- but not complete strangers, unlike most who face off over the course of a season.
In this week's SAC Sound-off, Joseph never mentions the score of that game -- Notre Dame won 2-1 -- but instead, the perspective she gained from this opportunity to see a familiar face on the opposing bench. Click to read her take.
