Dondre Watson had six 3-pointers and finished with a career-best 20 points to help Palatine past Plainfield Central in tournament action hosted by Marshall on Saturday.
Roosevelt Smart also had 20 for the Pirates (12-8), who will face Metea Valley in the first of two games on Monday as the tournament continues.
Point guard Chris Macahon finished with 13 points and Josh Baldus had 10 for Palatine. Coach Eric Millstone said many of Watsons 3s were the result of crisp passes from Macahon.
Hes always been a really good shooter, Millstone said of Watson, but Chris did a really nice job of getting him the ball in the right spot. He was getting good looks.

Smart had 19 points, Baldus had 16 and Greg Grana 13.
Jimmy Ward had 12 points and Joe Biko 11 for Hoffman Estates.
