OKC would claim the No. 2 seed if it wins out, the Lakers lose out and Dallas loses once.
The Thunder's final game is at home against Milwaukee on Wednesday, while the Lakers close out the season that same night at — you guessed it — Sacramento.
The Thunder has signed guard Robert Vaden from the Tulsa 66ers and assigned him back to Tulsa.
Originally acquired by the Thunder from Charlotte during the 2009 NBA Draft, Vaden has played the entire 2010-11 season with the 66ers, averaging 10.4 points, 2.4 rebounds, 2.2 assists and shooting 39.2 percent (74 for 189) from 3-point range.
A 6-foot-5 product of Alabama-Birmingham, Vaden averaged 17.6 points, 4.9 rebounds and 2.1 assists his senior season in college and spent the 2009-10 season with Imola in the Italian second division.
Sunday's game at the Lakers will begin the Thunder's 17th and final back-to-back of the season. OKC has swept six back-to-backs, is 12-4 on the first night and 9-7 on the second night. Last year, the Thunder was 17-19 overall in 18 back-to-backs. … OKC is 30-11 with Serge Ibaka in the starting lineup and 17-4 when starting either Kendrick Perkins or Nazr Mohammed.
