For one week at least, Shaquille O'Neal and the Heat met their match in Danny Fortson and the revitalized SuperSonics.
Vladimir Radmanovic scored a season-high 27, including 11 in the fourth quarter, and the Sonics beat Miami for the second time in six days, 108-98 on Sunday night.
The Sonics ended the Heat's franchise-record 14-game winning streak on Monday night in Miami.
"It was a physical matchup," Dwyane Wade said of the inside duel between O'Neal and Fortson. "Shaq got the best of that matchup, but the Sonics got the best of the Heat."
Radmanovic hit three of his five 3-pointers in the final period and the Sonics ended a two-game losing streak by outscoring the Heat 13-1 in the final 4:40.
O'Neal had 28 points, 11 rebounds and five blocked shots for the Heat, who had an eight-game road winning streak broken.
