It was back to North America for the 2010-11 season, playing 42 games for the Oklahoma City Barons of the AHL as well as 3 games with their parent club, the Edmonton Oilers for his most recent NHL appearances.
Gerber returned to Sweden for two seasons, beginning by spending 2011-12 with the Vaxjo Lakers before moving to Rogle BK for the 2012-13 season.
Following the conclusion of the Swedish regular season, Gerber once again joined the Switzerland National Team for his ninth World Championships. Switzerland was placed in Group S, the "S" standing for Stockholm, as the tournament location was shared with Helsinki, Finland. Switzerland shocked the hosts by defeating Sweden 3-2 in their opening night game. They next raised eyebrows by defeating Canada 3-2 in a shootout, with Gerber stopping 7 of 8 Canadian attempts.
Next to fall was the Czech Republic, who they put away with 3 third period goals on their way to a 5-2 win. Now through the toughest part of their schedule and full of confidence, the Swiss rolled through Slovenia 7-1, Denmark 4-1, Norway 3-1 and Belarus 4-1 to win the group undefeated with 6 wins and an overtime win for 20 points, two ahead of the Canadians.
In the playoff round, they again faced the Czech Republic, coming out on top 2-1. They advanced to play the United States, easily defeating the Americans 3-0 to guarantee themselves a medal and advance to the championship final. There, they met Sweden, who they had defeated in their opening game, but, playing again in Stockholm, the Swiss fell 5-1 in the final but earned a terrific silver medal for Switzerland and Gerber, who went 4-2 in the tournament with a 1.81 goals against average and a 92% save percentage. It was the best Swiss result at the World Championships since their only other previous silver medal back in 1935, a span of 78 years and their first medal of any kind in 60 years!
Gerber then returned to his native Switzerland for the first time since 2004-05 when he signed with the Kloten Flyers of the Swiss National League A, posting winning records for each of his first two seasons with the Flyers.
