Defending champion Andy Murray is out of the Sony Ericsson Open in Miami after losing his second-round clash with Mardy Fish 6-4 6-4.
Murray, who received a first-round bye and was seeded third, was guilty of several errors in falling to the world number 101.
Fish, while clearly the underdog, had the crowd on his side and got plenty of help from Murray, who struggled with his forehand as he blew a 3-1 lead and 40-0 advantage in the first set to begin his demise.
Fish then broke Murray again early in the second set to take control of the match, which he won with a cross-court volley.
“I just wasn’t very good today, and I’m gonna need to get a lot better, ” said Murray on www.atpworldtour.com.
“If you leave the ball short in the middle of the court, it’s very easy for guys to attack and be aggressive.
“You don’t get away with playing that way against guys that can serve well that are difficult to break and play very aggressive on the return.”
There were no such problems for world number one and top seed Roger Federer, who needed a little over an hour to brush aside lucky loser Nicolas Lapentti 6-3 6-3.
Federer converted each of the three break points he earned, while saving the only one he conceded.
Fifth seed Robin Soderling powered his way past Peter Luczak, hitting six aces in a 7-6 (7-5) 6-0 victory.
Ninth seed Fernando Gonzalez was also a straight-sets winner, beating Yen-Hsun Lu 6-4 6-4.
Seventh seed Marin Cilic breezed past 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.
