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.

Chandler Parsons anticipates being booed in his first game at the American Airlines Center since leaving the Dallas Mavericks in free agency.But Parsons, whose Memphis Grizzlies play in Dallas on Friday night, believes Mavs fans would have ridiculously flawed logic if they do boo him.Parsons has been bombarded with negative feedback from Mavs fans on social media since signing a four-year, $94 million maximum contract with Memphis in July. Critics have focused on his injury issues -- both of his seasons in Dallas ended prematurely due to surgeries on his right knee -- and accused him of stealing money from Dirk Nowitzki, who took a hometown discount to give the Mavs salary-cap space that ended up being used to pay Parsons.Houston, I get it. I said some stupid stuff on the way out of Houston [after three seasons], Parsons told ESPN, referring to the boos he gets from Houston Rockets fans every time he returns to the Toyota Center as a visitor. Dallas, I dont understand. Its like getting mad at somebody for getting in a car wreck and breaking their arm. Like, how in the world can you be mad at somebody for getting hurt? It makes no sense. Thats just so wrong to get mad at somebody for getting hurt, like they want to go through the rehab, want to go through the pain, want to go through the misery of not playing.ddddddddddddI can never understand that aspect of it.So when it comes to Dallas, youre going to get mad at me because Dirk decided to take less money to bring in a really good player and then unfortunately he gets hurt? Thats why youre mad? Sure, boo.Due primarily to concerns about his knee, Dallas did not make Parsons an offer after he declined to exercise his player option, which would have paid him $16 million this season. Parsons told ESPN he would have taken a lot less than the maximum to re-sign with the Mavs, but hes happy he ended up going to the Grizzlies.I think its a perfect situation for me, said Parsons, who missed the first six games after his rehab extended into the regular season and is trying to work his way into a groove while under a strict minutes restriction. I see so much potential that I can add to this team. It just kind of solidifies that I made the right decision. ' ' '
