2008-09: Mercier finished his collegiate career this season, appearing in 40 games with Miami University (Ohio) (CCHA). He tallied 14 goals and 29 points as a senior, his second best total with the RedHawks. MU was defeated by Boston University in the NCAA Frozen Four final.
2007-08: This marked the net-minders second season with Lewiston (QMJHL), which saw Delmas post a 17-13-4 record with a 2.84 GAA and a .903 save percentage, not as good as his rookie campaign, but still respectable.
2008-09: In his third season with the Lewiston MAINEiacs (QMJHL), Delmas went 9-25-1 with a 4.11 goals against average and a .867 save percentage, his worst season with the club to date. Expect to see him with the Quebec Remparts (QMJHL) for 2009-10.
2009-10: Started the year with the Quebec Remparts, but was traded to the Halifax Mooseheads. Put up better numbers with Halifax.
2010-11: Delmas certainly had an eventful 2010-11 season of travel. He played for the QMJHL Halifax Mooseheads, CHL Wichita Thunder, ECHL Wheeling Nailers, and AHL Hamilton Bulldogs. He spent most of the season in the ECHL, where he had a record of 15 wins, six losses and two overtime losses in 24 starts for the Nailers. The young goaltender had a solid 2.03 goals against average and an excellent .928 save percentage in 24 regular season games. Delmas played two AHL games late in the season for Hamilton where he recorded a win, an overtime loss and had a goals against average of 1.92 along with an excellent .933 save percentage. Delmas wasn't as solid in the ECHL playoffs for Wheeling when he had eight wins, five losses appearing in 15 ECHL playoff games. He sported a 3.13 goals against average with an okay save percentage of .903. On July 5, 2011, the Montreal Canadiens signed Delmas to a three year entry level contract.
2011-12: Delmas has played fairly well but was inconsistent for stretches of the 2011-12 season with the Wheeling Nailers in the ECHL. The young goalie posted a 18-14-1 record with a good 2.50 goals against average, a solid .909 save percentage and three shut-outs in 37 ECHL games. In mid-December, he suffered his second concussion in three months when his head struck the ice after falling back to make a save and missed three weeks of play. In the second half of the year, Delmas played four games in the AHL with the Hamilton Bulldogs where he showed flashes of brilliance in two games and struggled in the other two starts.
A solid, positional goaltender, Delmas is unflappable between the pipes and plays a mature, steady game beyond his years. Always square to the shooter, he never gives up on the puck and possesses a quick glove, but at times he struggles controlling rebounds. Though he has settled down from his rookie year, Delmas is sometimes a bit too adventurous in and around the net and doesn’t have the quickness and agility to always make up for his aggressiveness.
Delmas will be battling Robert Mayer for the Bulldogs' back-up goalie position. He must perform as good if not better than last season or the young goaltender could be loaned to the Wheeling Nailers again this year if the Bulldogs choose not to keep three netminder in Hamilton for the 2012-13 season.
