Wimbledon 2013: American Sloane Stephens defeats Monica Puig to book quarter-final spot Within a matter of minutes, Williams was on her way home and Stephens, 20, had turned her own last-16 match on its head, beating fellow youngster Monica Puig 4-6 7-5 6-1 in a gruelling two hours and four minutes on Court 18. The 17th seed had her own trials and tribulations against 19-year-old Puig, who was a point away from serving for a place in the last eight, having already become the first woman representing Puerto Rican to reach the second week of a grand slam. But the ability and tenacity which saw her stun Williams in the quarter-finals in Melbourne helped her get one of the breaks back and she very nearly drew level in a punishing 10th game, in which she saved three set points and missed three break points before succumbing. Both youngsters continued to trade blows like veteran streetfighters, with more brutal exchanges in game 11 seeing Stephens save a break point that could have meant curtains. It proved the turning point as the American immediately broke herself to take the match into a decider. Spaniard Puig, who stunned fifth seed Sara Errani in round one in what was her first grass court match since turning professional, immediately took Stephens's serve. But her game suddenly distintegrated - her frustration boiling over at one stage when she angrily disputed a line call - and Stephens reeled off six in a row in a matter of minutes, taking match point at the second attempt. With Williams out could even better days lie ahead?
