Klay Thompson scored 23 points and the Golden State Warriors set an NBA playoff record with 21 3-pointers to overcome another injury to Stephen Curry and beat the Houston Rockets 121-94 on Sunday for a 3-1 series lead. Golden State was just fine without him thanks to 3-point shooting that led to a 41-point third quarter. The Warriors bested the NBA record they shared for 3s in a playoff game when Brandon Rush made one from the top of the key with about 2 1/2 minutes left.
