SALT LAKE CITY — The Lakers outscored the Utah Jazz, 29-17, in the second quarter and threatened to turn Game 4 tonight into a runaway by halfway. OK, who’s kidding who? It was a rout. The Jazz had no answer for Pau Gasol, who had 17 points and seven rebounds by halftime. Kobe Bryant added 12 points. The Lakers’ bench responded, too. Lamar Odom scored seven points, Shannon Brown had six and Jordan Farmar added three. Carlos Boozer had a rough start, scoring only four points on 1-for-6 shooting. Deron Williams led the Jazz, who were trying to avoid being swept for the first time their history, by scoring 11 points.
