2007-08: This was the Mayer's first season of North American hockey. He backstopped Saint John (QMJHL) with a 16-10-1 record, a 3.77 GAA and a .877 save percentage. He also appeared in five games for the Swiss U20 club at the WJC, but didn’t post good numbers. He was also invited to the 2008 Home Hardware CHL-NHL Top Prospects Game.

Despite playing in more games, his numbers improved over last season. Expect to see him make the jump to Hamilton (AHL) next season
2009-10: Mayer was assigned to the ECHL Cincinnati Cyclones. He split time with fellow rookie Jeremy Smith (NAS). Mayer spent the bulk of his season with Cincinnati of the ECHL, posting a .889 save percentage in 31 games. He was also given a game with Hamilton, only allowing 2 goals against with a .931 save percentage.
2010-11: Mayer struggled as a 21-year-old in his first full AHL season with Hamilton. Pushed into the starting role after an injury to Bulldogs' starter and one-time NHL goalie Curtis Sanford, Mayer struggled in the starter's role and then saw limited action after AHL veteran Drew MacIntyre was signed. For the season, Mayer finished with a 9-10-2 record with a 3.06 GAA and .890 save percentage for a Hamilton team that won the AHL's North Division and advanced to the playoff semifinals. Mayer did not make any playoff appearances with MacIntyre starting all 20 games.
2011-12: Mayer struggled at times in his second AHL season with Hamilton as the back-up to Nathan Lawson. He continues to allow in bad goals while losing his angles but can have flashes of excellence and still needs to show more consistency in his starts. The young Czech-born goalie has posted 14-18-1 with an improved 2.94 goals against average and a respectable .909 save percentage on the last place Bulldogs in 39 AHL games this year.
2012-13: Mayer played for Montreal's AHL affiliate in Hamilton in his fourth pro season. He played a team-high 38 games and was 16-17-3 with a 2.93 goals against and .908 save percentage. The Bulldogs missed the AHL playoffs after finishing last in the North Division. Mayer was re-signed by Montreal to a two-year contract as a restricted free agent in July, 2013.
Troubled by inconsistency, Mayer shows flashes of greatness but has surrendered his fair share of soft goals. An aggressive netminder, Mayer comes out of his crease quickly to play the angle, but sometimes gets burned by his eagerness. With solid positioning and a great glove hand, Mayer has the potential to be much better than what he has shown so far.
