Problem:Question: How old was the goaltender that Pickard replaced in his NHL debut? Passage:In the 201415 season, Pickard began the year with the Monsters but was recalled to the Colorado Avalanche on October 16, 2014 after Semyon Varlamov was placed on injured reserve, he made his NHL debut the same day against the Ottawa Senators as he had to come in for Reto Berra who was injured in a collision; Pickard allowed four goals on 27 shots in a 5-3 loss. Pickard was sent back to the Lake Erie Monsters on October 25 but was recalled on November 18 after Semyon Varlamov suffered a groin injury. Pickard earned his first win on November 22 after coming in to relieve an ineffective Reto Berra, Pickard stopped all 17 shots he faced in an eventual 4-3 Overtime win. After more poor play from Berra, Pickard became the starting goaltender and continued in impressive form until Semyon Varlamov permanently returned to the team, after which Pickard became the team's primary backup goaltender. Pickard was returned to Lake Erie on December 28, in order to resume a starting goaltender role. In the 201516 season Pickard began the year with Colorado's new AHL affiliate the San Antonio Rampage, he was recalled early on in the season when Semyon Varlamov suffered a groin injury. He would return to the club in late December when Reto Berra injured his ankle, Pickard recorded his first NHL shutout on January 16, 2016 against the New Jersey Devils.
