Steven Bergwijn scored the game's only goal in the 61st minute, firing in from close range. After breaking the deadlock, Dwight Lodeweges's team controlled the game at the Johan Cruyff Arena in Amsterdam, restricting Poland to just one shot on target.
It was also a disastrous race for Red Bull, with Max Verstappen retiring from the midfield with engine trouble, and Alex Albon finishing down in 15th after a scrappy performance in which he received a five-second penalty for impeding Romain Grosjean's Haas.
But after that goal, Poland took control of the game for the rest of the first half, and their domination paid off when Kamil Glik equalized just before half-time.
"I played pretty aggressively from the first ball, and that's pretty necessary against her because she's a great player who can hit a lot of great angles," Mertens said. "I tried to step into the court, and thankfully my first serve was working, so that was a big advantage."
In terms of the title race, reigning champions Real Madrid will be confident of defending their crown - not because they look any stronger than they did last season, but because main rivals, FC Barcelona and Atletico Madrid (at the moment at least) look weaker.
"The two words were first added to the emblem to make sure people understands it represents the Paralympic Games. The IPC was concerned whether Chinese people knew its meaning if they were removed," explained Lin, who was worried by the difference between the two emblems when placed together.
There were also many hand sanitizing points and people were asked to keep two meters distance from one another.
Meanwhile, playing in front of empty stands (for the opening months of the campaign at least) once again promises to make a mockery of home advantage and make games much harder to predict.
"Last year's French Open was the most special tournament of my career so this is not a decision I have made lightly," the Australian added.
The remaining of the match have been controversial as Gao Lin was shown his fourth yellow card of the season in the 71st minute after complaining to the referee. The Chinese international is going to miss Shenzhen's next match against his former club Guangzhou Evergrande next Wednesday. Enditem
