OKLAHOMA CITY (AP) – The Oklahoma City Thunder are trying to use the same formula as the Dallas Mavericks to even up the Western Conference finals: Get angry and get a win.

After claiming home-court advantage with a win in Dallas in Game 2, the Thunder got flattened in the first quarter of Game 3 and gave it right back. They fell into a humbling 23-point hole in the first 14 minutes on their home floor, and never could climb their way out of it.

Now, they face what guard Daequan Cook calls a “must-win” situation in Game 4 on Monday night. Otherwise, Oklahoma City would be behind 3-1 when the series shifts back to Dallas.

All-Star point guard Russell Westbrook said Sunday “you have to be angry” after a loss at home.
