Mastrosimone, a second-round pick (No. 54) in the 2019 NHL Draft, hoped to make an impression during Red Wings development camp in June, and had an assist in the first period of the Red & White Scrimmage, the camp's final event. But later in the period, he broke his ankle blocking a shot, which changed his offseason plans.
Mastrosimone (5-foot-10, 158 pounds) is expected to recover in time for his freshman season at Boston University, where the 18-year-old will work on getting faster and stronger. It will be a step in his development after he had 105 points (47 goals, 58 assists) in 114 games the past two seasons with Chicago of the United States Hockey League. He had 15 points (seven goals, eight assists) in 11 USHL playoff games last season.
"I can't wait to be part of that little rivalry (Boston University vs. Boston College)," he said. "That's going to be great. Growing up on Long Island (East Islip, New York), I got to know a lot of Boston guys, which is awesome."
