On Tuesday, he will make an unofficial visit to Rutgers' campus to watch practice, which will be the Scarlet Knights' second full-fledged scrimmage of the spring, and also get to know more about the program he is currently favoring.
"I would say I'm sort of close," the 6-foot-2, 215-pound Mastromatteo said about making a decision. "I definitely want to have it done before summer. I know that."
Mastromatteo is one of Rutgers' top linebacker targets, and has been since making a visit to campus for junior day and leaving with an offer.
And in his discussions with the Scarlet Knights' coaching staff, and through their actions, has he learned how important he is to Rutgers' 2012 recruiting class?
"Definitely," he said. "Just by them staying in contact with me. The first day they could come out to a school (for spring evaluation), they came to my school first. They always tell me how high on the list I am, how much they really want me."
It is something Mastromatteo is weighing heavily in the recruiting process.
"It's great to hear stuff like that," he said. "You know you're going somewhere you're really wanted, and they really want to use you. They like my personality as well, not just as a football player but as a person."
As a junior, he made 90 tackles and had 11 sacks playing outside linebacker, a position that allows him to showcase his abilities getting up the field. He also forced two fumbles and had an interception.
Mastromatteo also attended junior day at Boston College and learned about the program there, but Cincinnati remains a bit of an unknown despite his offer.
"I've been trying to find a date (to visit Cincinnati), but it's sort of hard right now," he said. "I really wanted to get out to Cincinnati. I've been to Boston College already, and I'd like to get out there again, but I'm not sure."
