Britain's Aljaz Bedene battled back from a set down to reach the second round of the Miami Open.
Bedene, 26, who failed in his bid on Wednesday to be eligible to represent GB in the Davis Cup, beat Spain's Roberto Carballes Baena 4-6 6-2 6-3.
His reward is a meeting against another Spaniard, 17th seed Roberto Batista Agut.
Fellow Briton Heather Watson is due in action later against American Sloane Stephens.
