NEW YORK -- With torrential rain wiping out play on all other courts at Flushing Meadows Thursday afternoon, Andy Murray banked another straight-sets win under the new roof at Arthur Ashe.Novak Djokovic, his main rival for the US Open title, had benefited from a walkover Wednesday, and Murray looked to get his business done quickly against a tricky opponent in Marcel Granollers.The world No. 2 was seemingly racing toward the third round when he went 5-2 up in the first set. But a 10-minute long service game and three missed set points later, Murray was broken by the Spaniard.The next game went even longer and Murray eventually took his seventh set point after 67 minutes. From there, the 2012 champion raced through the second set and closed out a 6-4, 6-1, 6-4 win in two hours, 23 minutes.It was tough -- had it gone to five-all then the first set becomes a really tough one and all the pressure is on me having led 5-2 and had bunch of set points, Murray told ESPN tennis analyst Brad Gilbert on court.Thankfully I got through the 5-4 game and the momentum was back with me. He made it tough for me, hes very good with hands. Im glad to get through it in three sets.Murray got just 43 percent of his first serves in play and made 28 unforced errors, but he hit 34 winners and won 65 percent of points on his second serve.I hit quite a lot of winners, although my first-serve percentage wasnt great, he added. I won a lot of points behind my second serve. Thats been good the first two rounds. Its a little bit different serving under the roof, a little bit heavier conditions.It was an efficient enough performance from Murray.
