John Isner ended his winless start to the year at the New York Open, while Fabio Fognini was a casualty at the Argentina Open.

Isner was 0-2 in 2019 following defeats at the Auckland Open and Australian Open last month but the big-serving American celebrated victory in New York on Wednesday.

The top seed at the ATP 250 tournament, Isner defeated Bernard Tomic 7-6 (9-7) 6-4 en route to the quarter-finals midweek.

"I had a long time to stew over again not doing well Down Under. It was very tough. I certainly wasn't feeling too great about my game after that," said Isner, who hit 33 aces in the one hour, 14-minute win.

"But the only thing you can do is just continue to keep working hard. For me, keep working on my body. And I used that time to really get stronger. You have to look at it as a blessing in disguise. It really just gave me a bunch of time to keep working hard in the gym, but most importantly just enjoying time with my family."
