World No. 1 Serena Williams had overcame a tough test from 30- year- old wildcard Anabel Medina Garrigues to book her place in the Madrid Open semifinals with a 6-3, 0-6, 7-5 victory on Friday.
William cruised through to the last eight without conceding a set, until her game with Garrigues where she did enough to edge a tight opening set against the World No. 63 with just the one break of serve when her opponent was serving 3-4 down.
The Spaniard, however stunned William in the second set as she charged into the 15- time Grand Slam winner’s serve to break three times and was never under any pressure on her own serve as she amazingly took the set 6-0.
Early in the third set, Williams appeared to have regained composure as she got off to a 2-0 lead, before Garrigues came soaring back again and broke in successive games to move ahead 4-2.
Victory was in sight for the Spaniard until she faltered as she gifted the break straight back before the next three games went with serve.
Williams made the final and decisive break when she pounced on a weak second serve to power a backhand down the line and go 6-5 in front before holding to love to set up a semifinal meeting with either of Sara Errani and Ekaterina Makarova.
