Julius Erving scored 28 points and blocked a shot with 13 seconds remaining, and Caldwell Jones made four free throws in the final 67 seconds as Philadelphia defeated the Hawks, 98-95, in overtime last night in Atlanta and advanced to the second round of the National Basketball Association playoffs.

The victory gave the 76ers a sweep of the best-of-three miniseries. The 76ers have the home-court advantage in the best-of-seven series with the Milwaukee Bucks.

Jones broke a tie at 93 when he made two free throws with 1:07 left. Maurice Cheeks then stole the ball to give the 76ers possession again.

Erving had a basket nullified for charging with 30 seconds to play, but blocked Dan Roundfield's shot with 13 seconds to go.

Nine seconds later, Jones made two more free throws for a 97-93 lead. Roundfield, who had a game-high 29 points, scored on a dunk with two seconds to play.

Erving scored the final point with one second remaining.

Roundfield had forced the game into overtime when he made a 15-footer with 12 seconds remaining in regulation to tie the score at 90.

Roundfield then teamed with Rory Sparrow to trap Cheeks at the buzzer.
