LOS ANGELES -- After four seasons in the Golden State Warriors supporting cast, Harrison Barnes is seizing his opportunity to be the main man in Dallas.Barnes scored 31 points, Seth Curry added 23 and the Mavericks won their second straight game after an 0-5 start, 109-97 over the Los Angeles Lakers on Tuesday night.Two days after Barnes scored a career-best 34 in the Mavs victory over Milwaukee, he hit 11 of 18 shots at Staples Center while leading Dallas past the Lakers for the 11th consecutive time since April 2, 2013. Barnes scored seven consecutive points after Los Angeles took a lead with 7 1/2 minutes to play, and his teammates finished it off.Im just being aggressive, Barnes said. That was the biggest thing in my first few games (with the Mavs), figuring out when to be aggressive and when not to. You just kind of have to leave the switch on, and if you fail, fail aggressively.Its working: Barnes has scored 30 points three times in Dallas last six games after hitting that mark once in his first four seasons with Golden State.After getting their first win of the season Sunday against Milwaukee, the Mavs won again without injured Dirk Nowitzki and Deron Williams. Nowitzki missed his second straight game with a sore Achilles tendon, while Williams missed his second straight game with a strained calf muscle.Dallas used only eight players in LA, but it was enough.This is two team efforts, just scrappy and grinding, Barnes said. Everyone is getting in the mix offensively and defensively. Its not always pretty basketball, but were getting it done, and thats the most rewarding thing about it.JJ Barea had 18 points, seven rebounds and eight assists for the Mavericks, who beat the Lakers on the road for the sixth straight time.Our guys stuck to a game plan of tempo and patience and discipline, and they won the game, Dallas coach Rick Carlisle said.TIP-INSMavericks: Carlisle shared a quick pregame moment with Lakers F Metta World Peace, who played for Carlisle in Indiana a decade ago.

Lou Williams scored 15 points for Los Angeles, which rallied from an 11-point deficit in the second half before failing to execute in the final minutes.I thought we did a little better job in the second half fighting, Walton said. I thought we were a little soft in the first half. We had our chances.Young scored 13 points in the first 3:15, staking the Lakers to an early lead. Dallas scored the final 11 points of the half to move ahead 58-54.HEADING BACKBarnes had his latest monster game one night before he returned to Oakland to take on the Golden State Warriors for the first time since leaving as a free agent during the summer. Barnes was a key player on the Warriors 2015 championship team and last seasons runner-up, but left after the Warriors renounced his rights when they landed Kevin Durant.When asked if the homecoming was anything special, Barnes said: Nah. ... Its another game. Were 2-5, so its another game. Trying to 3-5 and go back home.SHORT-LIVEDThe Lakers (4-4) had moved above .500 for just the second time since Dec. 6, 2013, with a victory over Phoenix on Sunday.

It was 2013 and he was a sleep-deprived US Open racket stringer, standing 18-hour days for nearly three weeks straight. It was late and most of the other stringers had left for the night, but he was one of a pair required to stay until the last match of the day was completed.Rafael Nadal, who had just completed his match, unexpectedly walked into the stringing room.Thanks guys, he said. Ill see you tomorrow.The few stringers left in the shop were surprised and grateful that their work had been noticed and appreciated.He walks out of his way to come into the room and say thanks, Tankersley said. And you dont get that very often.Players come in with six to eight rackets, and want synthetic strings such as Luxilon or natural such as cow gut, loose or tight, strung first thing in the morning or just before a match. When things go right, the stringers rarely hear about it. But when they go wrong, frustrations can be as high as the stakes at the US Open.Wilson, the equipment manufacturer, runs the operation for the US Open and a few other tournaments. The 18 stringers who work for the US Open qualifying tournament and main draw go through a surprisingly rigorous selection process. Every year since 2009, Tankersley has flown from Dallas to New York, where he strings rackets to ridiculous specificity, some days from 7 a.m. until the last ball is struck.They may not see their names in lights or be introduced to a standing ovation at Arthur Ashe Stadium, but Wilsons Ron Rocchi said the stringers here are every bit the professionals as the players they quietly work for. They stand in rows spinning the frames as they work, focused down as tennis luminaries and champions walk by the glass window in front of them.We average 18 minutes, Rocchi said. We could string faster, but we need quality and consistency.On Monday, the group completed 514 rackets, a record for the tournament. And it doesnt matter if its Andy Murray or one of the juniors playing on an outer court; each player gets the same attention and accommodation.Anyone can request anything, and well always say yes, Rocchi said.There is an exception -- and thats when a player needs a racket restrung in the middle of a match. So lets say John Isner is pllaying on the Grandstand and breaks strings on three rackets.ddddddddddddHe might have a ball boy or girl run a racket straight to the desk of the stringing room. Tankersley or longtime stringer Yat Kong would then assign it to the next available worker, and 20 minutes later the racket would be back on the court.Its a factory, said Simona Halep, the No. 5 seed in the womens field. They are very fast. They are very good. All the rackets are made in time and very well done.With stringers from a variety of countries, including Japan and Argentina, players can explain their requirements in their own language.Many of the stringers, such as Joe Heydt of Omaha, Nebraska, grew up playing and stringing their own rackets. Heydt was 17 when he broke a string, and then another, and then went to his local tennis store to figure out how a racket worked. The owner hired him to string in the shop. Eventually, Heydt ended up opening a branch of Racquet Corner in Omaha.Each stringer has his or her own machine -- the Formula One racers of racket stringing, Rocchi said -- that has digitally stored preferences for height and tilt. Those specifications might not make a big difference when stringing one or two rackets, but given the volume, its huge.Its a professional machine, and its made for people who are going to be stringing all day long, Heydt said.By the end of a tournament, Heydt says his fingers are calloused and feel like hard M&Ms from forcing strings into alignment after the stringing is complete. He has a metal tool to help, but its not as effective as feeling for himself where the cross-strings need to sit on the mains.Both Heydt and Tankersley say that the cache of being a US Open stringer is good for business. But that isnt the pull that keeps them coming back. Its not the travel, either. Heydt has been to the Australian Open seven times but spends most of his days at his machine or sleeping.Instead, its a chance to be on the grounds at a Grand Slam, to see the players and, on a night before he won the US Open, have Nadal come in and say thanks.Every job has a pinnacle, Heydt said, and this is the pinnacle of racket stringing.
