(AP) -- The Washington Wizards still aren't sure who they'll be facing in their first playoff series since 2008. The potential matchup could make a big difference between a likely first-round exit and advancing.

Washington can match its second-best record over the last 35 years with a road victory over the Boston Celtics on Wednesday night.

The Wizards (43-38) are one game ahead of Charlotte for the sixth seed in the Eastern Conference and one game behind Brooklyn for the fifth spot. A Nets victory in Cleveland on Wednesday would prevent Washington from passing them.
