Fish upsets Murray

Defending champion Andy Murray's Miami title defence lasted just one game as he suffered a shock 6-4 6-4 defeat at the hands of Mardy Fish.

Murray started well but soon had no answer for Fish's power game, as the British number one lost his Sony Ericsson Open title in his opening match.

The world number three looked short on confidence and, after a poor showing at Indian Wells, he suffered another early exit to extend his recent slump.

The Scot had looked to be cruising as he sat 3-1 in front after an early break and led 40-0 on his own serve, only to fluff a drop-shot into the net.

Fish got back into that game and duly broke back, and he converted another break to go on and take the set, which had looked unthinkable after four games.

The American was far better in the second set, with Fish breaking Murray in the opening game and holding under pressure before sealing the win on his second match point.

"It feels great," Fish told Sky Sports 3. "I had knee surgery and re-dedicated myself, I really put my body to work and rediscovered my game and how much I really want to be out here."

World number 101 Fish insisted that Murray was still a man to be feared despite his recent shortcomings, and does not think he has lost his edge.

"You have to play relatively flawless tennis on your serves against Andy Murray. He's the best returner we have in my opinion, him and Federer are the best we've got.

"I need free points on my serve, he's going to beat me from the baseline most of the time unless I strike pretty quickly and I was able to do that.

"To be honest he's one of the guys that really shows up, week in and week out, in my opinion he does it really well, he's three in the world so he must be doing that."

For top seed Roger Federer it was a different story however as the world number one took a little over an hour to brush aside lucky loser Nicolas Lapentti.

Federer converted each of the three break points he earned and saved the only one he conceded on his way to a 6-3 6-3 victory.

Fifth seed Robin Soderling powered his way past Peter Luczak, smashing six aces in a 7-6 (7-5) 6-0 victory.

Seventh seed Marin Cilic beat Stephane Robert 6-3 6-2, while ninth seed Fernando Gonzalez and Tomas Berdych were also straight-sets winners.

Fernando Verdasco, seeded 10th, saw off Dudi Sela 6-1 6-2, but 20th seed Gilles Simon lost out to Horacio Zeballos, who claimed a 6-2 6-3 win.

There were also victories for Mikhail Youzhny, Florent Serra, Jurgen Melzer, Marcos Baghdatis, Feliciano Lopez, Stanislas Wawrinka, Juan Monaco, and Philipp Petzschner.
