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.
