A former world number eight, Sock won just one singles match last year – at the Laver Cup.

Giron created 10 break points and converted four on his way to victory in 76 minutes.

Coming off a run to the Australian Open quarterFinals, Sandgren suffered a 6-7 (5-7) 6-3 7-6 (7-3) loss to Steve Johnson.

Sandgren squandered seven match points in a last-eight loss to Roger Federer in Melbourne and the fifth seed was edged by Johnson.

Sixth seed Miomir Kecmanovic and Italian veteran Andreas Seppi posted wins over Tommy Paul and Damir Dzumhur respectively.

At the Argentina Open, Casper Ruud was the only seed in action and eased past Pablo Andujar 6-2 6-3.

Pablo Cuevas, Federico Delbonis and Thiago Monteiro also moved into the second round.
