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: Birmingham Seaholm's Colton Kinnie

Senior ♦ Football

The Maples’ third-year starting quarterback led Seaholm to a 56-49 win over rival Birmingham Groves in a Division 2 District Semifinal on Friday after Seaholm also had defeated Groves 21-14 in the regular-season finale the week before. Kinnie ran for four touchdowns and threw for two more as his team improved to 9-1 this fall.

Seaholm earlier repeated as Oakland Activities Association Blue champion and is a combined 17-4 over the last two seasons after finishing just 1-8 in 2021. The 6-foot-2, 220-pound Kinnie has been a major contributor to the turnaround, and he’s joined by an experienced cast of seasoned starters including twin brother Granden. Both also joined the Seaholm baseball varsity as sophomores and helped that team to a District title in the spring.
