ATLANTA — Josh Smith scored 29 points as the Atlanta Hawks built a 17-point lead at halftime, then withstood an Indiana comeback over the final two quarters to even the series with a 102-91 victory in Game 4 on Monday night. After struggling much of the second half, Smith made every big play down the stretch. He swished a rare 3-pointer, came up with an offensive rebound to set up a 3 by Kyle Korver, then finished off a fast break with a right-handed dunk.
