Accoring to the Post-Gazette, the arbitration hearings are set for Ryan Malone and Brooks Orpik.
Malone's hearing is Friday, July 21st, while Orpik will have his hearing on Monday, July 24th. Rulings will be announced 2-3 days after the hearings.
Malone is by far the more interesting case, given that he's still pretty far apart from the team in terms of salary, accoring to Shero. Given how he played the first half of last year, I'd be surprised if he is awarded anything huge. Half a season does not a superstar make, as Yoda might say.
