Murray told BBC Sport, “It was a tough match. I made it hard for myself in the second set.”
“For me, it’s nice,” Murray said of the British success. “I know all of them fairly well.
“I’ve obviously spent a lot of time training with James, really more the last 12, 18 months. Aljaz I don’t know so well. Heather obviously had a good win today, too. Liam’s a nice guy. He’s good fun to be around.”
“It’s good for British tennis. The more wins and more players we can have in these events, it makes a difference,” he also added.
Two times champion Rafael Nadal was in imperious form as he dispatched Thomaz Bellucci 6-4, 6-2, 6-4 in 2 hours and 11 minutes. This is Brazilian’s fifth straight loss to Nadal in straight sets. Nadal hit only one ace and made five double faults during his first round match.
