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: Midland Dow's Melanie Kolnitys
February 6, 2026
Melanie Kolnitys ♦ Midland Dow
Senior ♦ Basketball
The Chargers’ senior point guard unfortunately finished her season – and high school basketball career – earlier than expected last week. But given the circumstances, it’s difficult to imagine a more incredible ending. Kolnitys entered Dow’s Jan. 28 game against Grand Blanc needing 22 points to reach 1,000, and with knee surgery scheduled for the next day. She scored only two points during the first half, but 20 during the second to reach the milestone on her final basket.
Kolnitys initially had been injured during a soccer game as a sophomore, tearing an ACL and both meniscuses in her right knee. A four-year varsity basketball standout, she played the last few and especially this winter knowing follow-up surgery was a possibility, and although she hoped to make it through her entire senior season, her ability to sprint had been affected enough to require that surgery Jan. 29. Kolnitys would like to return for the end of her soccer season this spring, and will continue her soccer career this fall at Saginaw Valley State. She plans to study biology on a pre-veterinary track.
