"It's top players, so if you wait for the mistake it's never going to happen," Garcia said. "If you let Pliskova breeze and take your serve, you're never going to make a return, and then it's 6-4, 6-4 and you're done in one hour."
PP Sports, owned by Chinese retail giant Suning Group, had signed a three-year deal with Premier League in 2016. The broadcaster has reportedly withheld a payment of 160 million pounds rights fees which were due to happen in March.

Garcia looked untouchable in the first set and for much of the second, blasting 30 winners and breaking Pliskova's serve three times en route to the 6-1, 7-6 (2) victory.

"In the end it got too dark to go for 6.15 meters and I felt it was unsafe to continue any further," said the world silver medalist. "I felt I was in the zone. But you have to be prudent."
