It was a bad day for Canadians at the Paris Masters tennis tournament on Monday as both Vasek Pospisil and Denis Shapovalov lost their first-round matches. 

Pospisil won his opening set, but then dropped the next two in close fashion as the Canadian fell to France's Nicolas Mahut 7-5, 5-7, 6-7 (4). Shapovalov was beaten in straight sets, 6-4, 6-4, by Julien Benneteau of France.

"I feel good physically and I have a lot of energy," Mahut, who entered the tournament as a wild card, told ATP in a press release. "I was serving better and moving better. A victory at a Masters 1000 is extremely pleasant to have."

Pospisil's 2017 season ends with back-to-back losses in the first round; the veteran previously lost to former doubles partner Jack Sock  3-6 7-6 (7), 7-5 last week at the Swiss Indoors.
