WASHINGTON — Kyle Korver was the Atlanta Hawks' closest defender as Paul Pierce shimmied to his left and launched a 3-point try, hoping to extend the Washington Wizards' season by forcing overtime in Game 6 of the teams' second-round series. The shot swished, apparently tying the score at the buzzer. Pierce raised his arms; both teams began thinking about OT. Then, though, the play was reviewed, showing the clock expired before Pierce released the basketball.
