Sophomore guard Tyler Nelson scored 14 points to lead the Raiders, who dropped their first game, to Lowell, last Friday.

“I think sitting in that locker room after that Lowell game, in which Lowell absolutely took it to us, these kids, to a man, said ‘let’s not let this happen again,’ ’’ said Central Catholic coach Rick Nault, whose squad improved to 16-1.

“It’s a very determined group that I’ve got. I’ve had a lot of good teams in the past. I don’t think I’ve ever had as hard a working team as I have right here and they truly believe in each other. We had a couple of great days of practice after Friday night and we felt pretty good coming in today.’’

The Raiders went from a man-to-man defense to zone and jumped to a 10-point lead after being tied at the half, 26-26.

The 20th-ranked Lancers (10-3), who only scored 8 points in the third, managed to cut the lead to 3 points late in the fourth, but never got any closer.

Lawrence’s speed and athleticism gave the Raiders problems in the first half, as senior point guard Franklin Martinez was able to get into the lane and create opportunities for his team. But the Lancers couldn’t keep up the momentum in the second half.

Martinez finished with 11 points to lead Lawrence, who also received 9 points apiece from freshman Luis Torres and sophomore Roberto Speing.
