NASHVILLE, Tenn. -- Riley LaChance gave Vanderbilt a second-half spark, which was just what Vanderbilt needed.The junior guard scored nine of the Commodores first 11 points in the seconds half as Vanderbilt pulled away for a 75-52 win over Norfolk State in the on-campus portion of Las Vegas Invitational on Friday night.His surge turned a nine-point halftime lead into a 16-point advantage and the Spartans (2-2) never got closer than 11 the rest of the way.Riley played his best five minutes of the season to start that second half, Vanderbilt coach Bryce Drew said. He gave us a lot of energy on both ends, which kind of started on the defensive end, I thought. He really got out in transition and hit some 3s that were key for us.Matthew Fisher-Davis led Vanderbilt (2-1) with 18 points, including four 3-pointers, and LaChance added 12, highlighted by three 3-pointers.I was definitely in a good rhythm and my teammates did a good job of pumping me up, and we do a good job of pumping each other up, LaChance said. I think when we made that run in the second half we had really good energy and really good togetherness.Jeff Roberson grabbed 11 rebounds and scored 11 points for the Commodores, who hit 10 of 28 from 3-point range.Norfolk State lost to a Southeastern Conference team for the second time in a week, including a 78-74 defeat at Mississippi State on Nov. 11.A lot of it was our defensive mistakes, to be honest with you, Spartans coach Robert Jones said. We left Fisher-Davis three times on rotations and he had wide-open 3s, so a lot of it was us, not them really. The overall energy wasnt how we play for whatever reason.Jonathan Wade remained hot for the Spartans with 20 points and seven rebounds. Wade scored a career-high 34 points in Tuesdays 91-55 rout of Elizabeth City State.We kind of beat ourselves tonight, Wade said. If our energy level is not there, were not the team were capable of being. We kind of have mental lapses sometimes as a team.The Spartans made only 30 percent of their shots from the floor, hitting 18 of 60.Norfolk State led by three points before Vanderbilt went on a 10-0 run to take a 32-25 lead on LaChances 3-pointer with 3:26 left in the first half.The Commodores missed their first six shots from the floor, but hit 14 of 16 foul shots in the first 20 minutes to help them go on top 37-28 at halftime.BIG PICTURENorfolk State: The Spartans werent able to contain Fisher-Davis and LaChance, and their perimeter defense couldnt stop the Commodores 3-point shooters.

Vanderbilt passed the ball crisply with 16 assists, compared to two for Norfolk State.GOOD WEEKFisher-Davis has looked good in both of Vanderbilts wins this week. Hes played a complete game, Drew said. We all know how well he shoots the ball, but hes been putting the ball down on the floor a little bit and hes been passing it and on the defensive end I think hes done a much better job taking pride in defending his man.UNBALANCED SCORINGWade was the only Spartan in double figures. Alex Long, Zaynah Robinson, Micah Goss and Carrington Ward went a combined 6 for 33 from the floor.UP NEXTNorfolk State visits Butler on Monday for the second game in a 10-day road trip.Vanderbilt hosts Bucknell on Monday in the final of a three-game homestand.

Now sister Serena will get a chance to even the score. Robson, a quickly improving 19-year-old British player, beat Venus Williams 6-3, 6-2 on Monday to set up a second-round match with top-ranked Serena. Robson won the Wimbledon junior title at 14 and at last weeks Madrid Open, she upset fourth-seeded Agnieszka Radwanska before losing in the third round to 16th-seeded Ana Ivanovic in a third-set tiebreaker. "I just like it on big courts against these huge players because I just go out there with nothing to lose," the 39th-ranked Robson said. "I can remember seeing (Venus) play at Wimbledon when I was about 10 and I was kind of blown away with the speed that she hit the ball. "Today when she hit it in the centre of the racket it was basically point over, so I just had to take my chances." Both players struggled with the wind at the Foro Italico, with Robson hitting eight double-faults and Williams six. However, Williams errors came at more inopportune times, with two double-faults in the final game. "Its always hard to play high quality tennis in that wind," Robson said. "I wish it could have been a higher standard but Im happy to have won." Serena, who won the Madrid title Sunday, watched the match from the stands. "(Robson) has a great game," the younger Williams sister said. "Shes really young, still. Shes just so free and she looks great on the court and shes so smooth and shes a lefty, so that just adds a notch to her whole level. "Ive never played her before. Ive always wanted to. So I have a tough second-round match." Serenas only title at this clay-court tournament came in 2002 but if she continues playing the way she did in Madrid -- and in her previous two tournaments, which she also won -- shell be difficult to beat. &"She is playing probably her best tennis," Robson said.dddddddddddd"So its going to be insanely tough but Im just going to go out there and do my best." This tournament is the last major warm-up for the French Open, the years second Grand Slam, which starts May 26. The top 32 players get seeded for Grand Slams. "Ive said since the start of the year that I wanted to be seeded for Wimbledon and it would be great if I were to be seeded for Roland Garros as well," Robson said. The top-eight seeded players in Rome have first-round byes.
