(AP) — The Warriors took a big step forward in securing home-court advantage in the playoffs with yet another offensive surge in the second half, keyed by a stifling defense. More importantly, Golden State put some more distance between itself and a possible first-round matchup against Memphis — one of only two teams to have beaten coach Steve Kerr's squad more than once this season. Klay Thompson scored 21 of his 31 points in the second half and the Warriors pulled away in the fourth quarter to beat the Grizzlies 106-94 on Sunday for their seventh straight win. Stephen Curry added 21 points and 11 assists, Andre Iguodala scored 20 and Draymond Green had nine points and seven rebounds as the Warriors (59-14) extended their lead to 2 ½ games over the San Antonio Spurs in the race for the top spot in the West. Memphis had beaten the Warriors twice previously this season and was attempting to become the first team to notch three regular-season wins against Golden State since the Spurs' four-game sweep in 2013-14. Mike Conley scored 29 points, Zach Randolph added 15 and JaMychal Green had 13 points and eight rebounds for the Grizzlies, who were without center Marc Gasol (left foot strain). Randolph had 12 points in the first half and Conley made all seven of his free-throw attempts in the second quarter to pace Memphis inside, while Green repeatedly scored from the perimeter. Iguodala kept Golden State in it, shooting 5 of 6 with a pair of 3-pointers to help the Warriors to a 56-54 halftime lead.
