WATCH: Dodig pulls off improbable no- look hot shot

While a lot of attention has gone to Rafael Nadal, Novak Djokovic and Team Australia, Croatia has quietly gone undefeated so far at the ATP Cup in Sydney. On top of winning two ties, they've also earned the hot shot of the tournament (so far) thanks to Ivan Dodig's incredible no-look lob winner.

Dodig and Nikola Mektic were leading 6-2, 3-0 in the deciding match against Poland's Hubert Hurkacz and Lukasz Kubot when Dodig's fast reaction created an improbably winner.

The ATP Cup's new video review system was used to see if Dodig's body touched the ball, which would have meant a lost point for Croatia. The umpire couldn't confirm any illegal maneuvers were used.

“It was very tough even for me to feel if I touched, because I didn't hit it with [my] hand, because I would say if I hit it with my hand. I hit something with the grip, but I felt a vibration, maybe. It's tough,” Dodig told the ATP. “The point, it's happened once in the lifetime… when I hit it it was kind of a lob on the line. It [was the] best possible scenario."

Dodig and Mektic would win 6-2, 6-1 to seal the 2-1 victory for Croatia. The Croatians toped the Austrians in their first round-robin match, 3-0 and will face Argentina next.
