PHILADELPHIA, April 8 (AP) -- One good half was good enough for the Philadelphia 76ers.
Andre Iguodala scored 25 points and the 76ers rallied from a 17-point third-quarter deficit Sunday night for a 109-104 overtime victory over the Atlanta Hawks.
Willie Green's 3-pointer with 4:23 left in overtime gave the 76ers their first lead since midway through the first quarter and put Philadelphia ahead for good. Joe Smith scored 14 of his season-high 18 points after halftime, while Samuel Dalembert finished with 16 points and 10 rebounds. Green scored 14 points.
The 76ers kept their slim Eastern Conference playoff hopes alive, as they trail the eighth-place Orlando Magic by four games with six to play.
"It was a tale of two halves," Philadelphia coach Maurice Cheeks said. "In the first half, they were getting up and down the floor, outrunning us and getting easy shots. Their zone bothered us in the first half, but in the second half we attacked the zone and figured it out."
"It's something that will be addressed (Monday)," Woodson said of Smith, who averages 16.1 points and is the Hawks' top scorer with Joe Johnson sidelined by a right calf injury. "I sent him in because of conduct, but I'll address it (Monday) in Atlanta."
Lue hit all five of his shots and scored 13 points in the first quarter as Atlanta used an 18-4 run to build a 30-24 lead.
When Lue cooled down in the second quarter, Slava Medvedenko picked up the slack. Medvedenko, who had played sparingly in just 10 games this season, scored 10 points in the period, and the Hawks took a 53-41 lead into halftime, despite 13 points from Iguodala.
Atlanta shot 57 percent from the floor (21-for-37) and enjoyed a 26-17 rebounding edge in the first half.
The Hawks extended their lead to 17 early in the third quarter, with Solomon Jones catching a lob pass over Green for a dunk and then Smith catching an alley-oop pass from Williams for a reverse layup that gave Atlanta a 64-47 lead.
But Philadelphia finished the quarter on a 13-4 run to draw close. Rodney Carney's 3-pointer with 1.1 seconds left in the third trimmed Atlanta's lead to 74-70 entering the fourth. Consecutive three-point plays by Bobby Jones and Dalembert helped the 76ers pull within 85-82 midway through the fourth quarter.
Philadelphia slowly chipped away at the lead and finally tied the score at 93-all when Iguodala maneuvered through Atlanta's defense for a ferocious dunk with 56 seconds left. The Hawks had the final shot to win in regulation when Anthony Johnson won a jump ball from Iguodala with 17 seconds left, but Lue missed an off-balance runner at the horn.
Notes: Medvedenko had not played more than five minutes in a game -- and had scored just 18 points -- all season. ... Lue also finished with a game-high nine assists and tied a career-best with eight rebounds. Carney sprained his left knee with 1:48 left in regulation and did not return. ... Philadelphia has won eight of the last 10 meetings between the teams and has won five straight overtime games.
