The Oklahoma City Thunder aren't building momentum for a postseason run as they have dropped seven of their past nine games. The Thunder will look to begin a turnaround when they host the Los Angeles Lakers on Tuesday in the fourth contest of a five-game homestand.

Teams are starting to separate just a bit at the bottom of the Western Conference playoff bracket, and the San Antonio Spurs are drifting in the wrong direction. The Spurs will try to snap out of a recent funk and jump back into the fight for the fifth or sixth seed when they host the Atlanta Hawks on Tuesday.

All-Star guard James Harden continues to put up huge numbers and he will attempt to post another high-scoring effort when the Houston Rockets visit the Sacramento Kings on Tuesday. Harden scored 50 or more points in three of the past six games and collected 50 points, 11 rebounds and 10 assists in Saturday's 119-108 home win over the Kings.

The battle for the No. 1 seed in the Western Conference goes head-to-head when the Denver Nuggets visit the Golden State Warriors on Tuesday. The defending-champion Warriors hold a one-game lead for the top spot after showing off just how good they can be in a 137-90 thrashing of the Charlotte Hornets on Sunday.
