MEMPHIS, Tenn. — At halftime, the Atlanta Hawks figured they had played cautiously long enough. With a burst of energy, tough defense and 3-point shooting from Lou Williams in the third quarter, the Hawks were able to pull away for a 93-83 victory over the Memphis Grizzlies on Saturday night. "I think we were just trying to play it safe because (the Grizzlies) are a really good team," Atlanta guard Jeff Teague said of the first-half effort.
