As a high-​​school stu­dent growing up in Brain­tree, Mass., Brit­tney Rizo spent a great deal of her time as a pro­fes­sional figure skater. The sport’s gru­eling travel schedule, explained Rizo, now a rising junior studying Eng­lish at North­eastern, often caused her to fall behind in class — espe­cially in math, a sub­ject with which she strug­gled. But one math teacher in par­tic­ular, Kyle Piazza, took the time to help Rizo catch up on her class work.

Piazza passed away last October after bat­tling cancer, but Rizo will always remember him “as a teacher who lit up a room of stu­dents over cal­culus. He could get everyone to love it.”

Rizo noted that Piazza was pas­sionate about every­thing he did in life, including playing com­pet­i­tive wiffle ball on a national level.

That’s why she and her brother, Jared, have orga­nized a wiffle-​​ball tour­na­ment this weekend to honor Piazza’s memory and raise money for the Jimmy Fund, which sup­ports the fight against cancer in chil­dren and adults at Boston’s Dana-​​Farber Cancer Institute.

The double-​​elimination tour­na­ment fea­turing teams of four will begin on Sat­urday at 9 a.m. at Braintree’s Hollingsworth Park. Teams can reg­ister on the day of the event for $150 or sign up by Thursday for $90.

Rizo noted that Brain­tree has been incred­ibly sup­portive of the tour­na­ment, which will fea­ture teams of North­eastern stu­dents, including one from her sorority, Kappa Delta.

When Piazza was sick last year, she and others par­tic­i­pated in the Boston Marathon Jimmy Fund Walk, raising a total of $20,000 for Team Piazza. At the time, Rizo promised him that she’d raise even more money and get many others involved this year.

I wanted to keep my promise to him and make sure I did the best I could,” she said.
