Andy Murray feeling confident after Santiago Giraldo win

Andy Murray has acknowledged that he is in good form after moving into the last 16 of the Miami Open with victory over Santiago Giraldo.

Murray failed to produce his very best tennis in the match, but he managed to step it up when he needed to and ran out a 6-3 6-4 winner.

He told Sky Sports News: "I felt like I played a good match. When he really started going for it at the end, I lost my timing a bit and had to try and take a couple of steps back from the baseline. But I thought it was a good match from my side.

"I wanted to take advantage of his not having a big second serve, so I wanted to take time away from him, get him off balance at the beginning of rallies."

Murray will face Kevin Anderson in the next round.
