Last week was the busiest on the MHSAA school schedule. And it was a great one for Pontiac Notre Dame Prep.

Over three days, the Fighting Irish won three District and one Regional championship, plus two more track and field individual Finals titles.

Successes were celebrated across six sports.

Thursday: Notre Dame’s boys golf team won its District, led by individual medalist Aaron Knutson; the senior shot a 71.

Friday: The boys lacrosse team won its third straight Regional title with an 11-2 win over Warren DeLaSalle in Division 2. (The Irish since have lost to Grand Rapids Forest Hills Central in a Semifinal.)

Saturday: Senior Sara Barron finished an outstanding track career by winning the 1,600-meter run with a Division 2 Finals record time of 4:51.67. She also won the 800 in 2:15.83 and teamed with Taylor Timko, Sarah LewAllen and Candice Mark to finish third in the 1,600 relay.

Timko also scored the game-winning goal as Notre Dame’s girls soccer team beat Detroit Country Day 1-0 in a Division 3 District championship game.

The Irish’s softball team beat Bloomfield Hills Lahser and Detroit Country Day by a combined score of 25-1 to win its sixth straight District title. Notre Dame had only one error on the day and didn’t give up a hit in the five-inning win over Lahser.

Finally, the girls tennis team posted its best MHSAA Finals finish to cap its best season ever. Notre Dame placed seventh in Division 4, keyed by runner-up finishes by Erin Moncrief (No. 4 singles) and Maddie Riley and Gabby Bering (No. 4 doubles). Notre Dame ended with a 10-1 dual record, losing only to eventual Division 4 champion Bloomfield Hills Academy of Sacred Heart.
