2005-06: Reto Berra was chosen in by the St. Louis Blues in the fourth round, 106th overall, of the 2006 NHL Draft by the St. Louis Blues.
2006-07: Berra split time between Swiss “A” League side ZSC Lions and “B” League squad GCZ. He spent a lot of time as the back-up for the two teams, appearing in six games with GCZ and two with ZSC. Berra received some unexpected playing time in the playoffs, when ZSC’s starting goaltender was injured. His play was respectable, but he couldn’t quite manage a needed victory. The highlight of Berra’s season may have been the World Juniors. He compiled a worth .899 save percentage on an often out-matched Swiss team.
2007-08: Berra spent the season in the Swiss-A leageue, backstopping Davos with a 9-7-0 record; he finished the season with a 2.73 goals against average.
At 6-4, 194 pounds, Berra has a big-frame, yet is remarkably flexible for his size, and seems just as comfortable making saves while on his back as he is in normal situations. He also exhibits excellent poise for a young goaltender, and never seems to be shaken, no matter what the situation.
Berra was acquired by the Calgary Flames in April of 2013 in the deal that brought Jay Bouwmeester to the St. Louis Blues. Berra was dealt again, at the 2014 NHL Trade Deadline, by the Calgary Flames to the Colorado Avalanche in exchange for a draft pick.
