A night after what their coach called a ``flat game,'' the Celtics held the Wizards to 1-for-14 shooting at the start, then were barely better at the end.
Washington's only scoring in the first 8 minutes came on Kevin Garnett's goaltending call, and Pierce hit a key 3 down the stretch to help Boston improve to 1-2.
Washington dropped to 0-2 after its home opener in front of a sellout crowd of 20,308 that occasionally included folks chanting ``Let's go, Celtics!'' Washington is still without two starters: point guard John Wall, the No. 1 overall pick in the 2010 draft, and center Nene.
