Acapulco, Mexico, 26 February 2019 |

John Millman surged into the second round of the ATP tournament in Acapulco, Mexico following a straight-sets win over Spaniard Marcel Granollers on Monday night local time.

The Queenslander completed a 6-3 6-4 victory over the qualifier in under 90 minutes to set up a meeting in the last 16 with German Peter Gojowczyk.

Millman owns a 3-1 winning head-to-head record over Gojowczyk, with their last match – won by Millman in three sets – coming at the Miami Masters last year.

Another Aussie, Jordan Thompson, fell in his opening-round match to No.6 seed Francis Tiafoe.

After winning the first set, Thompson fell to a 3-6 6-4 6-3 defeat in a match finishing after midnight.

Millman built a 3-0 lead in the second set but the dogged Granollers, ranked No.111, fought back to lock scores at 4-4.

Yet Millman broke in the very next game and served out the match at his first opportunity.

Four more Aussies – Alex De Minaur, Daria Gavrilova, Nick Kyrgios and Alexei Popyrin – play their first matches on Tuesday.
