Penguins forward Nick Spaling filed for salary arbitration.
Three other Penguins forwards who also are restricted free agents -- Brandon Sutter, Jayson Megna and Bobby Farnham -- were eligible, but did not request it.
Defensemen Simon Despres and Philip Samuelsson are restricted free agents, but weren't arbitration-eligible.
In arbitration, the player and team propose a salary for the coming season, then argue their case before a neutral third party, who decides on the player's salary. The club gets to say whether it wants the agreement to cover one season or two.
Teams also have the option to "walk away" from the awarded salary, in which case the player becomes an unrestricted free agent.
Spaling, acquired from Nashville in the James Neal trade June 27, is free to negotiate with the Penguins until his hearing, the date of which has not been set, and it's possible he will have a contract before a hearing takes place.
Spaling also requested arbitration as a member of the Predators last summer, but worked out a one-year deal worth $1.5 million -- a $400,000 raise from his previous contract -- before his hearing was held.
A total of 20 players filed for arbitration by the deadline at 5 p.m. Saturday, according to the NHL Players' Association. Boston defenseman Matt Bartkowski, a Mt. Lebanon native, is one of them.
