Miletic, 20, has played in two NHL preseason games with the Penguins this year, scoring the opening goal in Pittsburgh's win in Columbus on September 22. He also played in all three Prospect Challenge contests in Buffalo in early September, tallying two points (1G-1A) in the opening game against Boston. Miletic also skated in Pittsburgh's prospect development camp in July.
Last year, the 6-foot, 196-pound Miletic led the London Knights of the Ontario Hockey League with 37 goals in 65 games, a total that ranked 12th in the OHL. He had 55 points (37G-18A) overall on the season, which ranked him fifth on the club.
A native of Bloomfield Township, Michigan, Miletic has spent the past two seasons with the Knights, skating in 100 regular-season games, compiling 40 goals, 29 assists and 69 points. Before joining London, Miletic played the 2014-15 season with the Green Bay Gamblers of the United States Hockey League, scoring 12 goals and 27 points in 58 games.
Miletic is the third undrafted free agent signed by the Penguins in training camp, joining goaltender Alex D'Orio and forward Jordy Bellerive, both of whom also participated in development camp, the Prospects Challenge and NHL training camp before returning to their junior clubs.
