In the second quarter, Boston had a pair of layups where a Trail Blazers' player made a futile attempt to block the shot, leading to 3-point plays. Sasha Pavlovic had the first 1:02 into the quarter when he drove by Nicolas Batum, who made a weak slap at his arm.
Later, Pierce missed a layup, but tipped in his own shot and was fouled on the play by Kurt Thomas, who appeared to be standing behind him before making a brief effort that drew the foul. Pierce's 3-point play gave Boston a 56-23 lead.
