<p>NEW YORK — Joe Harris tied a franchise playoff record with seven 3-pointers, Kevin Durant scored 26 points and the Brooklyn Nets routed the Boston Celtics 130-108 on Tuesday night for a 2-0 lead in their first-round playoff series.</p>
<p>Harris had a career playoff-high 25 points and James Harden added 20 as the Nets unleashed their lethal offense after winning Game 1 largely with defense.</p>
<p>Game 3 is Friday in Boston, where the Nets will attempt to build on their first 2-0 lead in a series since they swept the New York Knicks in the first round in 2004.</p>
<p>This one might be headed toward the same result, with the Celtics unable to do much scoring in Game 1 or stop the Nets from doing tons of it in Game 2. </p>
<p>Marcus Smart scored 19 points and Kemba Walker had 17 for the Celtics. Leading scorer Jayson Tatum had only nine points on 3-for-12 shooting before leaving after just 21 minutes when he was poked in the right eye.</p>
<p>After the Nets scored just 16 points in the first quarter of Game 1, Harris had that by himself in the opening quarter of this one while going 4 for 4 behind the arc. </p>
<p>The Nets had started slowly in Game 1 and in the only game their Big Three played together late in the regular season, and on Monday coach Steve Nash said he thought it might be a while before his three stars could walk on the court and be firing on all cylinders.</p>
<p>It was only a day later for Harris, who led the NBA in 3-point percentage this season.</p>
<p>Harris made three straight 3-pointers to extend a three-point lead to 25-13 and there was a little gasp from the crowd when he then stole the ball and dribbled down on a breakaway, as if he might pull up behind the arc. Instead, he went all the way for the layup and a 14-point lead.</p>
<p>It was 40-26 after one period and Harden made consecutive 3s to open the second. That made it a 20-point game and it was never close from there. </p>
<p>Kyrie Irving had 15 points, six rebounds and six assists for the Nets, who made 17 3-pointers.</p>
