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.

Performance of the Week: Utica Eisenhower's Morgan Emerick
June 4, 2026
Morgan Emerick ♦ Utica Eisenhower
Sophomore ♦ Tennis
The Eagles' No. 2 singles player won her second-straight Finals championship at that flight, claiming all four of her matches Saturday at Midland Tennis Center in straight sets while giving up a combined 10 points on the day. She finished this season 37-0, running her two-year high school record to 74-1 – and she's won 71 straight matches, good for the fifth-longest streak in the MHSAA record book.
Emerick also was a gymnast growing up, but picked up tennis from her father and has emerged into a force. Her 37 wins this season rank sixth-most for a singles player in MHSAA history, and doubling her 74 from her first two seasons would put her among the top three in career victories when she graduates in two years. Only three of her victories this season went to third sets, and three of her wins came at No. 1 singles.
