Shira Springer of the Boston Globe reports: With a win today at home against the Washington Wizards, the Boston Celtics can clinch a playoff spot.

It is fitting that head coach Jim O'Brien plans to start using his playoff rotation today. That will include moving Tony Battie back into the starting lineup.

Paul Pierce knows the Celtics have to finish strong.

''We've just got to be consistent with what we're doing,'' said Pierce. ''Right now, in these last six games, we've got to play at a high level in every quarter, with every possession. We need to play with that type of consistency that we did a year ago with our defense.''
