Shapovalov served twice for the match, but eventually lost out to Spain’s world No. 101 Roberto Carballes Baena 7-5, 6-7, 6-3, 3-6, 8-6 after a five-hour epic.
And, after his singles involvement in the oft-criticized tournament came to an end on Thursday, Shapovalov took aim at the tournament’s administrators for failing to produce an environment and a tournament that gave the players the chance to compete at their best.
“Scheduling is absolutely awful,” said Shapovalov after his second-round exit.
“After a five-hour match, I have to play doubles now. It’s just like, it’s just complete trash scheduling. It’s disappointing.
“I mean, you’re in a Grand Slam and I don’t want to sound spoiled, but you expect at least some help from the tournament to help you compete.
“How am I supposed to come out and play doubles now after a five-hour match? It’s a first-round as well, they could have scheduled it way better.”
Shapovalov arrived at Roland Garros in solid form and had been earmarked as a potential dark horse for the tournament after breaking into the Top 10.
But he struggled to deal with the slow-playing court and the heavy tennis balls used at the tournament that have attracted criticism from a number of players.
“These conditions were completely stacked against me,” Shapovalov, who reached his first Grand Slam quarter-final at the recent US Open, said.
“It’s impossible to hit a winner with these balls. In my opinion, it shouldn’t be that heavy and that difficult.”
Shapovalov signed off by criticizing the bio-secure bubble which is meant to help prevent any COVID-19 infections.
“Honestly I think they’re not doing a good job. There’s really no bubble, especially in the second hotel, I heard,” he said.
“You can leave the hotel, you can go to the city, there’s no problem, there’s nobody stopping you.
“New York was done way better.”
