DALLAS -- Delonte West took Jason Kidd's advice, giving the Dallas Mavericks a badly needed late lift.
West scored Dallas' first six points of the second overtime, and the Mavericks held on for a 97-94 victory over the Portland Trail Blazers on Saturday.
Dirk Nowitzki's 20 points and Jason Terry's 19 led the Mavs, but West saved them when it mattered most.
West started the second OT in place of Kidd after West played only 15 seconds in the first extra session. The Blazers were double-teaming Nowitzki, giving West more room to look for his shot.
"J-Kidd told me to go out there and be aggressive because of the way they were playing Dirk," said West, who finished with 10 points. "I sparked my team right there in the second overtime."
West hit an 11-footer for Dallas to open the second overtime. West followed with mid-range jumpers on consecutive possessions to give Dallas a 93-89 advantage with 2:55 left.
