Josh Smith posted 22 points and 18 rebounds, and the Atlanta Hawks hung on to defeat the Boston Celtics, 83-74, in the opener of their Eastern Conference quarterfinal series. Smith became the first Hawk to register 22-plus points and 17-plus rebounds in a playoff game since Moses Malone had 24 points and 17 rebounds in Game 4 of a first-round series against the Milwaukee Bucks in 1989. Jeff Teague added 15 points and six rebounds, while Kirk Hinrich nailed four three-pointers en route to 12 points for Atlanta, which fell to Boston in seven games the last time these two combatants met in the 2008 Eastern Conference Quarterfinals.
