Miami, FL, USA, 24 March 2016 |

Sam Groth has scored a much-needed singles wing to advance to the second round of the ATP Miami Open in Florida.

The big-serving Australian dismissed Victor Estrella Burgos 6-3 6-2 in just 64 minutes on Wednesday.

The victory sets up a second-round match with 14th seed Dominic Thiem of Austria.

Coming into the Miami tournament Groth was on a seven-match losing streak, his last win coming in the first round of the Australian Open.

He slammed 10 aces and won 97 per cent of his first serve points throughout the win, which took his 2016 record to 2-9.

Fellow Aussie John Millman plays his first-round match on Thursday, while Nick Kyrgios, the No.24 seed, has been awarded a first-round bye.
