British No. 1 Andy Murray romped past 25th seed Feliciano Lopez 6-1, 6-4, 6-2 to reach the fourth round of the US Open on Sunday night. The win took the Scot, who is in pursuit of his first Grand Slam title, an hour and 54 minutes and secured the fourth seed a rematch with the American prospect, Donald Young, who embarrassed him in their only meeting at Indian Wells in March. In a first set that sped by in 26 minutes, Murray did not drop a point on his serve and took the first 14 points of the match, the left-handed Spaniard raising an ironic cheer when he finally got a point on his own serve at 15-30 in the fourth game. Murray resumed to impose rasping ground strokes and stylish serving and there was nothing Lopez could do about it. Lopez decided to risk daring raid on the net, forcing Murray to pass or lob in the second set, but Murray finally found the chance to break in the ninth game, then serve out for the set. Lopez wilted again in the third and lost the match when he hit a return long. Murray will next challenge up Young, who beat the world No. 4 when Young was ranked 143 in the world. The 22-year-old American has risen to 84 on the back of steady improvement and had his best win earlier on Sunday when he beat the 24th seed Juan Ignacio Chela 7-5, 6-4, 6-3. That followed an impressive victory over Stanislas Wawrinka. Young, a wild card here, long touted as a major talent, is one of those players who can beat anyone on their day but just don\'t have enough days.If they could pour all their good tennis into one tournament, these guys would be world-beaters.
