NEW YORK -- Andy Murray survived a scare to battle past an inspired Paolo Lorenzi into the fourth round of the US Open.Lorenzi, a 34-year-old Italian ranked 40th in the world and who had won just two Grand Slam matches coming into Flushing Meadows, was in the form of his life and pushed Murray all the way for two sets before his legs tired and Murrays class surfaced. Murray sealed a 7-6 (4), 5-7, 6-2, 6-3 win at Arthur Ashe Stadium.Lorenzi served for the first set before Murray broke him back and edged a tiebreaker, and the world No. 2 again was forced to break back from 5-4 down in the second set.But Lorenzi, who has won 18 Challenger titles, managed to break Murray again and this time served it out to tie the match at one set apiece.As Lorenzi took a comfort break, Murray regripped his racket and regrouped in his chair before racing through the third set. He then closed out the win in 3 hours, 17 minutes.Murray, bidding to become the fourth man in the Open era to reach all four major finals in a calendar year, next faces Grigor Dimitrov?of Bulgaria. Dimitrov continued his quiet progress under Murrays former coach Dani Vallverdu with a 6-4, 6-1, 3-6, 6-2 victory over Joao Sousa.It will be a tough match, Murray told ESPN tennis analyst Brad Gilbert on court. Grigor has been playing well the last few weeks. Hes a tough player, moves well. Got a lot of good shots. Very talented guy.

JOLIET, Ill. -- Neither Tony Stewart nor Ryan Newman felt the need to apologize for their actions Saturday night at Richmond International Raceway, but they reiterated they have put the incident behind them after spending more than 30 minutes with NASCAR officials Friday.Stewart and Newman, longtime friends, stood side-by-side for a few minutes afterward, answering reporters questions and joking with each other in the Chicagoland Speedway garage.We dont have to apologize to each other, Newman said.Stewart chimed right in: Youve got to remember, weve been teammates. Weve known each other since long before either one of us ever got an opportunity to come to NASCAR.Newman interrupted: Ill text you an apology later.The scene was much different Saturday at Richmond when Stewart cut in front of Newman, wrecking both of their cards in retaliation for what Stewart felt was too much contact from Newman in trying to get by. Newman, whose long-shot hopes of making the Chase for the Sprint Cup were ruined by Stewarts move, said the three-time Cup champion was bipolar and had anger issues and should be retired. (Stewart will retire from Cup racing after this year.)Id love to be able to be perfect and do everything right 100 percent of the time, Stewart said after the meeting. But we dont.Newman, who drove for Stewart-Haas Racing from 2009 through 2013, said he didnt regret what he said.Theyre just words, right? Newman said. More often than not, were men of our actions. Its just all abbout going out there and doing our job.dddddddddddd We all know it can be frustrating at times, whether its intentional or not. ... I dont have any regrets about what I said. I am frustrated by the situations and the actions that came about in respect to all of it.The two drivers were in the NASCAR hauler for about 35 minutes prior to the scheduled Sprint Cup practice. Sprint Cup Series director Richard Buck ran the meeting, a NASCAR spokesman confirmed, but NASCAR refused to comment on the topics of the meeting.Stewart indicated on Twitter that the meeting did not last that long.Both drivers have had past instances in their lengthy careers where they have had to go to the hauler to meet drivers they have had altercations with on the track. This one appeared more cordial than some of those in the past.Last week didnt play out in either of us favor, Newman said. Obviously we didnt want that to happen ever again. But what happened, happened.There are frustrations in our sport all the time. Whether you do it or you say it, you still have to be held accountable.Newman said he wont change how he races and is not the type of driver who will just take someone out on purpose.Its a deal where weve had a week to think about it, weve had a week to get over it, weve been in the trailer and talked about it, Stewart said. As far as were concerned, its over. ' ' '
