Oklahoma City Thunder notched a comfortable 114-108 win over the Los Angeles Lakers, highlighting the gap that had grown between the teams since they entered the season among the co-favorites.
Oklahoma City's win was matched by victories for the Memphis Grizzlies and the San Antonio Spurs as the trio continued to set the pace in the early stages of the new campaign.

The fans certainly remembered Harden, who was booed heartily during pregame introductions and every time he shot a free throw.
Memphis stayed atop the standings on winning percentage, moving to a 14-3 record with a 96-89 win over the struggling New Orleans Hornets.
Rudy Gay tied a season high with 28 points while former Hornets first-round draft choice Quincy Pondexter did the same with 16 points for the Grizzlies.

Stephen Curry scored 21 of his 28 points in the second half as the Warriors made it five wins from six games.
Joe Johnson scored a season-high 32 points for the Nets, who dropped their third straight and are now only half a game ahead of the Philadelphia 76ers.
The Sixers closed on the Nets and moved a game clear of Boston by beating the Celtics 95-94 in overtime.
Evan Turner, who had 26 points and 10 rebounds, made the last basket with an off-balance shot with 3.9 seconds left.
Boston guard Rajon Rondo had a chance to snatch back the lead but he slipped and his ankles buckled on the last possession.
It was a bad end to a good game by Rondo, who had 16 points, 14 assists and a season-high 13 rebounds.
It was similarly close in Indiana, where the Pacers suffered a 92-89 defeat by the Denver Nuggets.
Denver led most of the second half but found itself in an 85-82 deficit with 3:32 left. That's when 36-year-old Andre Miller took over, scoring eight points during a 10-0 spurt that turned it around for the Nuggets.
Indiana had a chance to force overtime, but George Hill's 3 bounced off the rim. Paul George led the Pacers with 22 points.
