Russell Westbrook scored 41 points and Robert Covington hit two clutch late 3-pointers while getting 14 points and eight rebounds in his auspicious Rockets debut, leading Houston to a 121-111 over the Los Angeles Lakers on Thursday night. James Harden managed just 14 points while the Rockets unveiled the latest version of their commitment to small ball by not playing anybody taller than 6-foot-7 against the hulking Lakers. Anthony Davis and the Lakers capitalized inside, but Houston still rallied from a late four-point deficit and ended the game on a 19-5 surge highlighted by two of Covington's four 3-pointers.
