On the day of Wellesley varsity basketball team’s final game of the season in February 2011, coach Paul “Wally” Seaver was diagnosed with ALS, also known as Lou Gehrig’s Disease.

“It’s a progressive disease, there’s no cure, and barely any treatment,” Seaver’s eldest son, also Paul, said. “For 95 percent of treatments, they don’t even know what caused it.”

In honor of his father’s fight against the disease, Seaver’s eldest son will be running the first annual high school basketball tournament, titled the “Wally” Seaver High School Invitational. The two-day tournament consisting of 16 teams will take place at Milford High School and Milford Middle School East on Saturday July 21 and Sunday July 22.

The 16 teams in the tournament are from Massachusetts, with the exception of one from Connecticut, and one from Rhode Island.

“It’s a life-changing situation, but the community has been great,” Paul Seaver said. “We’ve received tons of support, especially from Milford, but everywhere … We have 16 teams coming in.”

"Wally" Seaver coached varsity basketball at Franklin and Wellesley high schools, and coached youth teams for Milford. Seaver’s sons Paul and Daniel are also Milford High graduates.
