World No 1 seals victory easily in first round of Madrid Open
But Murray eventually made his move and let out a cry of joy with a brilliant cross-court halfvolley to break Copil’s resistance and take the first set 6-4.
One break in the sixth game was also enough for Murray to take the second set as he easily served out for the match.
Murray’s conqueror in Barcelona last month and potential quarter-final opponent Dominic Thiem eased past American Jared Donaldson 6-3, 6-4.
Ninth seed David Goffin became the first man into the third round with a routine 7-6 (7/3), 6-0 win over Germany’s Florian Mayer.
In the women’s Madrid Open, defending champion Simona Halep came from 5-2 down in the final set to beat Roberta Vinci 63, 2-6, 7-6 (7/2) to reach the third round.
“I was close to losing the match, but I stayed strong, stayed focused and I didn’t give up,” said Simona.
“That makes this match much bigger for me. It means a lot.”
Simona very nearly became the latest seed to fall in a decimated bottom half of the draw after early exits for Karolina Pliskova, Garbine Muguruza and Johanna Konta.
“I don’t know who lost and who is still in the tournament,” added Simona.
“I try to focus on myself a lot. As you saw today, I could have lost the match, so it doesn’t matter who is winning, who is losing. Every match is tough.”
Simona next faces Australian 16th seed Samantha Stosur.
Only three of the top 10 seeds remain as the woman Simona beat in last year’s final, Dominika Cibulkova, was swept aside 6-2, 6-4 by 20-year-old Frenchwoman Oceane Dodin. AFP
