Aljaz Bedene defeats Guillero Garcia-Lopez in ATP Chennai Open

The world number 156 dumped out second seed Feliciano Lopez in the last 16 on Thursday, and he repeated the trick against Lopez's fellow Spaniard 24 hours later.

The unseeded Bedene attracted little attention coming into this ATP 250 hard-court event, but the Slovenian's impressive displays have now earned him a semi-final spot after coming from behind to win 2-6 6-3 6-2.

Garcia-Lopez, the fifth seed, dominated the opening set and took the lead after reeling off five successive games from 2-1 down.

Bedene hit back in the second, eventually taking advantage of his fifth set point to force a decider.

And he continued his fine form in the final set, breaking the world number 36 immediately to gain the upper hand.

After rescuing two break-back points in the next game to consolidate, Bedene broke for a second time in the set in game five, and was able to go on to see out the victory and secure his last-four berth.

There he will meet another Spaniard in the form of third seed Roberto Bautista Agut, who edged past Lu Yen-hsun 7-6 (9-7) 6-4.

In the other half of the draw, defending champion Stanislas Wawrinka also prevailed in straight sets, 6-2 7-6 (7-4) against eighth seed Gilles Muller.

Top seed Wawrinka will now meet David Goffin, after the fourth seed saw off Andreas Haider-Maurer 7-5 6-2.
