Former Saint Mary's College star Matthew Dellavedova made the cut with the Cleveland Cavaliers.

NBA rosters don't need to be submitted until Monday, but the Cavaliers waived four players Friday to get down to a 15-man roster and Dellavedova wasn't among the casualties.

"Excited to be playing for the @cavs this year! Gotta keep working hard!" Dellavedova wrote on his Twitter account Friday, along with a picture of his locker after the Cavs' four cuts were announced.

"Delly just brings a toughness," Cleveland coach Mike Brown told "And, even though he's a rookie, (he provides) a veteran feel to the ballclub that you can't get out of young guys."

Dellavedova, who graduated last spring as the Gaels' career leader in scoring, assists, 3-pointers and field goal percentage, is expected to be the Cavs' third point guard, helping to back up All-Star Kyrie Irving.

The 2012 West Coast Conference Player of the Year, Dellavedova went undrafted in the spring. He played for Cleveland during the summer league and was invited to the team's preseason training. He played in all eight of the Cavs' preseason games, doing enough to earn a roster spot.
