The Celtics  got off to a solid start in Game 4, and have a 19-18 lead. It hasn’t been overly pretty, but as expected, Chicago came out aggressive but couldn’t convert that energy into points. A key for the Celtics was their impressive work on the defensive glass. They have grabbed 11 of an available 13 defensive rebounds.
Rajon Rondo  is once again leading the Celtics with seven points, three rebounds and two assists. Ray Allen  has also been efficient with six points on three shots. Paul Pierce  is off to a slow start–he’s missed his first three shots and Kendrick Perkins  picked up two quick fouls at the end of the quarter.
But everything else is going Boston’s way. Chicago is shooting just 36 percent and the Bulls are having trouble getting good shots. The bench will have to make a bit of a stand in the next 12 minutes.
