Hartzell, 24, played in one preseason game against the Detroit Red Wings and he stopped all four shots that came his way.
The 6-foot-4, 205-pound Hartzell was signed to a one-year entry-level deal (he re-signed to a two-year deal this offseason) by the Pittsburgh following his stellar year at Quinnipiac University, where he was named USA Hockey College Player of the Year.
Helping the Quinnipiac earn its first-ever trip to the Frozen Four, Hartzell finished the season with a 30-7-5 record, 1.57 goals against average, and a phenomenal .933 save percentage. He also registered five shutouts and was a finalist for the Hobey Baker Award (best college hockey player).
With a number of honors handed out to the young goaltender, Hartzell also collected the 2013 ECAC Player of the Year award, ECAC Hockey Ken Dryden Goaltender of the Year, and earned a spot on the ECAC First-Team All-Star team.
Hartzell is a product in the making, and the sky is the limit for his future; however, because the Pens already have two NHL goaltenders (Marc-Andre Fleury, Tomas Vokoun), Hartzell will continue to develop his game in the AHL.
Jeff Zatkoff played exceptionally well with WBS last season, but Hartzell should give him a run for his money towards the starting gig.
