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: Traverse City St. Francis' Grace Slocum
August 30, 2024
Grace Slocum ♦ Traverse City St. Francis
Senior ♦ Golf
The Gladiators' lead golfer has been on an incredible roll to begin this season; she's a combined 4-under-par after five tournaments and won all five events. She opened with a 15-stroke victory at the Traverse City West Invitational, won the two-day Lober Classic by 14 strokes and then last week's St. Francis Invitational by 18 strokes. This week she's added a 17-stroke win at the Grayling Invitational and Thursday carded a 6-under-par 65 to win the Petoskey Invitational by 10 strokes.
Slocum finished eighth at the Lower Peninsula Division 4 Final as a freshman, moved to third as a sophomore and placed fourth as a junior last fall as her team climbed the standings to tie for sixth place. She's also played hockey for several years but will be focusing on golf moving forward after recently committing to sign with Wisconsin. She plans to major in biochemistry and minor in nutritional sciences in preparation for medical school.
