Welcome to the beginning of Summer 2015's annual countdown of the top 25 Pittsburgh Penguins players under 25. Anyone in the organization, from unsigned collegiate draft picks down to NHL stars are eligible to be ranked, so long as they meet the age requirement. With hockey being a young man's game, it's always interesting to rank and keep track of the future. Last summer's ranking is in parenthesis.
#25 (#25) Matia Marcantuoni, C/RW, 21 years old, Wilkes-Barre Scranton (AHL)
The speedy Marcantuoni retains his 25th position in the rankings this summer, after a fairly unimpressive rookie season.
