Andy Murray claimed his first win in Miami in nearly three years as he saw off Alejandro Falla in straight sets to reach the third round of the Sony Ericsson Open.

36124 - Murray motors past Falla in Miami

The world No. 4 claimed an emphatic 6-2 6-3 win to taste victory at Crandon Park for the first time since he won the Miami Masters crown back in 2009.

After a nervous start, Murray proved his class, winning seven games on the bounce to wrap up the opening set before establishing a healthy lead in the second. Falla rallied to offer a late challenge, but the Scot held his nerve to wrap up a routine victory and set up a third-round clash with Milos Raonic.

Having not even won a set at Key Biscayne in three years, Miami came into the tournament on the back of an opening-round defeat to Guillermo Garcia-Lopez in Indian Wells a fortnight ago.

He was taken to deuce in his opening service game, but held his nerve to avoid an early break and despite seeing three break points pass him by, he grabbed a 2-0 lead at the fourth time of asking. However, his hard work was undone instantly as Falla broke back when Murray's cross-court forehand flashed wide.

A first ace of the match seemed to settle Murray and he forged ahead, taking a 4-2 lead when Falla's backhand found the net. The British No. 1 was dominant in the rallies but he was gifted the opening set after a double fault from Falla brought up two set points.

Having streaked away to clinch the opening set, Murray survived a wobble at the beginning of the second as he saved two break points before grabbing another break then tightening his grip on the match with a love service game.

Falla stopped the rot to prevent Murray winning an eighth consecutive game, but the damage was already done and although Murray handed the Colombian a break with his second double fault of the match, he immediately re-established his advantage, breaking for a fifth time before coolly serving out for the match.

Next up for Murray is the 26th-seeded Canadian Milos Raonic, who beat France's Arnaud Clement 7-6(7) 6-2.

Jo-Wilfried Tsonga booked his place in the third round with a hard-fought 7-5 7-5 win over Belgium's Xavier Malisse. The sixth seed dropped his opening service game, but recovered to take the opening set.

But the Frenchman did not have things all his own way in the second, as Malisse broke back after Tsonga took an early lead, but just as it looked like the second set was destined for a tiebreak, Tsonga grabbed a decisive second break to clinch victory.

Ninth seed Janko Tipsarevic saw off the challenge of David Nalbandian to claim a 7-5 6-3 victory to set up a third-round clash with Ukraine's Alexandr Dolgopolov who beat Croatian qualifier Antonio Veic in straight sets.
