ATLANTA — Devin Harris scored a season-high 25 points and Josh Smith nearly added a triple-double Monday night as the Atlanta Hawks beat the Cleveland Cavaliers 102-94 to improve their chances of securing home-court advantage in the first round of the playoffs. Smith had 18 points, 14 rebounds and eight assists before a sparse crowd in Philips Arena to help the Hawks (42-33) pull within one game of Brooklyn (42-31) for fourth place in the Eastern Conference. Reserve Marreese Speights scored 14 of his 22 in the final quarter, but the Cavs (22-51) did not seriously threaten after pulling within 58-56 early in the third period.
