Tim Henman began his quest for the Nasdaq-100 Open with a 6-3 7-5 win over Czech Republic qualifier Ivo Minar.
Henman, the sixth seed, was given a bye into the second round in Miami and his experience proved decisive against Minar, 10 years his junior.
He broke in the fourth game to take the opening set, and although big-serving Minar battled, Henman broke again in the 11th game of the second set.
"I kept my mind focused on what I was trying to do - it was good," he said.
The British number one will face Juan Ignacio Chela in the third round.
It was against the Argentine that Henman arguably produced the finest performance of his career, last year in the French Open quarter-finals.
He dropped just 10 games over three sets that day in Paris, on a surface and at a tournament which Henman had little affection for until remarkably reaching the semi-finals.
Henman's victory on Saturday was less noteworthy but the 30-year-old Englishman can be well pleased with his efforts against the dangerous Minar.
The Czech was a surprise finalist in Sydney at the start of the season, losing only to Lleyton Hewitt, and then almost beat Roger Federer in Dubai last month.
Henman is looking for a positive showing at this event, having dropped ranking points last week at Indian Wells, where he failed to match his feat of reaching the 2004 final.
Last year he beat the 25-year-old Chela twice, but in 2002 the South American crushed Henman at the US Open.
"[Chelas] is someone that I've had some good success against," Henman said.
"But he is one of these guys that if you're not quite on your game, then he can start to dictate.
"So it's clear-cut. I know the way that I need to play. He knows the way that I want to play. I know the way he wants to play. It comes down to who is going to be able to."
