NEW YORK -- Maybe Serena Williams simply wanted to put on a better show for her pal Beyonce.Looking rather displeased with herself at times, including when she shook her head and smirked on the way to the net for a post-victory handshake Thursday night, Williams still managed to tie Martina Navratilovas professional-era womens record with her 306th career victory in Grand Slam matches.Williams beat Vania King 6-3, 6-3 to reach the U.S. Opens third round.I just think it should have been a different scoreline for me. I feel like I made a lot of errors, Williams said. But, you know, theres nothing I can do about that now. What really matters is I got the win. Hopefully Ill just get better.Really? This performance didnt seem OK? After all, Williams delivered 13 aces with serves that reached 121 mph. She compiled a 38-4 edge in winners. She only dropped six games and needed all of 65 minutes to win.I just didnt have a great day, was her assessment.Yes, there were problems. The 28 unforced errors The return game: She won only 13 of 40 points on Kings first serves. Williams did, however, smack one backhand return winner in the final game.Music power couple Beyonce and Jay Z sat behind Williams coach, Patrick Mouratoglou, in the players guest box Thursday.Its always good, Williams said casually, to have Beyonce and Jay in the box.King noticed Williams negative body language as she headed to the net.I think Serenas a perfectionist. She always wants to play her best. ... If she doesnt play really well, shes always a little bit hard on herself, King said.Delivering 13 aces with the roof closed at Arthur Ashe Stadium, and showing no signs of a sore right shoulder that she said requires constant treatment, Williams improved to 306-42 in matches at major tournaments, a winning percentage of .879. Navratilova retired with a 306-49 mark.Only Roger Federer, with 307, has won more Grand Slam matches than Williams in the Open era, which dates to 1968 -- and he wont add to that total during this tournament because he is out for the season as he rehabs his surgically repaired left knee. Williams can equal Federers total by beating 47th-ranked Johanna Larsson of Sweden on Saturday.Would like to take one more step, Williams said while discussing her Slam win total. After a pause, she added: several more steps.Thats because itll take five more victories to win the championship, which would be her seventh at the U.S. Open and 23rd overall at majors, breaking Steffi Grafs Open-era record in that category.Never one to shy away from non-tennis interests, Williams recently appeared in one of Beyonces music videos and introduced a performance by her at the MTV Video Music Awards in Manhattan on Sunday night.Usually when people are there, I try to play better, especially if theyre famous and theyre doing so great at their job, Williams said. Its like I want to show them that Im good at my job, too.Williams then tacked on two words at the end of that thought -- minus today -- just to be sure everyone understood how she felt about this particular outing.---Follow Howard Fendrich on Twitter at http://twitter.com/HowardFendrichAir Max From China .

PITTSBURGH -- The Pittsburgh Penguins are 2-0-0 as they begin their defense of the Stanley Cup, and perhaps that shouldnt be a surprise.If theres anything the Penguins know how to do -- no matter the roster or the identity of the coach -- its how to follow up after winning a championship.After beating the Detroit Red Wings to win the Stanley Cup in 2009, Pittsburgh started out 9-1-0 in 2009-10. When captain Mario Lemieuxs Penguins began their quest for a third straight Cup in 1992-93, they opened up with 11 wins and two ties in their first 14 games.The current-day Penguins go for their third straight win at the newly renamed PPG Paints Arena on Monday night when they face the Colorado Avalanche (1-0). The Avalanche debuted under new coach Jared Bednar by beating the Dallas Stars, 6-5, on Saturday behind Joe Colbornes three goals.Colorado knows it has to stop getting off to the poor starts it experienced under former coach Patrick Roy over the previous two seasons. The Avalanche lost six of their first eight last season and eight of their first 10 in 2014-15, which forced them to try to play catch-up the rest of both seasons -- and they never caught up.Bednar liked how his team responded to a 2-0 deficit with five consecutive goals, though he wasnt happy that the 5-2 lead later became only a 5-4 margin.I liked the way we played offensively. I thought we were skating and on our toes, creating chances. (But) I think we have to get better defensively, Bednar said. We made some mistakes defensively up ice that gave them some numbers and gave them some scoring chances early in the game, and also a bit later.Bednar is learning how to coach in the NHL on the fly -- literally. He wasnt named the head coach until Aug. 25 following Roys unexpected resignation. Bednar barely had two weeks to get ready for training camp and to learn the league.Penguins coach Mike Sullivan can relate to that. Like Bednar, who won titles in the American Hockey League and ECHL, he was coaching in the minors last season when he was hired Dec. 12 to replace Mike Johnston in Pittsburgh.Thats why Sullivan said, more than 10 months later, the Penguins still are learning his style, even after winning the Stanley Cup with a half dozen of his former Wilkes-Barre/Scranton players in their room.What I like about this group is, over time, we have a better understanding of how to play in one-goal games, Sullivan said following a 3-2 win over the Anaheim Ducks on Saturday night. Were still trying to score, still trying to playy with speed, but I think our guys are making good decisions and forcing our opponents to play that 200-foot game.dddddddddddd Were hard to play against in that regard. I think thats when our team is at its best. Our guys have bought in.Marc-Andre Fleury is proving to be hard to play against, too. After barely playing since late March, when he sustained his second concussion of the season, Fleury has stopped 73 of 77 shots and posted a 1.92 goals-against average.Its been fun, said Fleury, who lost his starting job to the currently injured Matt Murray just before the playoffs began. I wanted those games in the preseason (to get accustomed to playing again). I wasnt as sharp as Id like to be. There still are things I want to get better at, but not right now. I feel better now than I did at camp.Colborne, a former University of Denver player, is feeling better the longer he gets accustomed to being with the Avalanche, He had 19 goals while playing for Calgary last season.Colborne and Real Cloutier (1979) are the only players in franchise history to get a hat trick in their first game with the team.The three goals, (thats) probably the way Im going to score most of them, and Im just fine with that, Colborne said. Its my job and something I take pride in, going to those tough areas and making them try to drag me down, draw some penalties and hopefully bury some.The Penguins, who had the day off Sunday as they play three games in four nights, already are making some adjustments as they compete without captain Sidney Crosby (concussion).On Saturday, Sullivan moved forward Conor Sheary to right wing on Matt Cullens wing, with Chris Kunitz on the left. Right wing Patric Hornqvist shifted to center Evgeni Malkins line so Scott Wilson could play on his natural left side. Sheary responded with a goal and a number of scoring opportunities.Youre kind of hitting yourself for not burying a couple of those, Sheary said. But its a good sign when youre getting a lot of chances.Bednar will switch goalies Monday, from Semyon Varlamov to backup Calvin Pickard, who stopped 47 of 48 shots in 1-0 Avalanche overtime loss in Pittsburgh on Dec. 18, 2014. Varlamov will start Tuesday against his former team, the Washington Capitals.The Penguins were 2-0 against Colorado last season, winning 4-3 on Nov. 19 in Pittsburgh and 4-2 at Colorado on Dec. 9, Johnstons last victory as coach.
