He replaces Gilles Meloche, who stepped down as the goalie coach in June after seven-years.
Prior to his promotion Monday, Bales was fulfilling duties as the Pens goaltender development coach, and he also helped assist in evaluating and scouting amateur netminders.
Thriving the young goaltenders in the AHL for the Wilkes-Barre/Scranton Pens, Bales helped guide goalies Jeff Zatkoff and Brad Thiessen to allow the fewest goals combined (178) in the league.
Zatkoff, who was the Pens third-round (74th overall) draft choice in the 2006 NHL Entry Draft, finished the 2012-13 campaign with a 1.93 goals-against-average — which was the lowest in the league.
He will now get the task of aiding Marc-Andre Fleury, and helping Tomas Vokoun remain his efficiency.
Pens Labyrinth would like to extend its congratulations to coach Bales on this excellent achievement.
