The Grizzlies shook off a first half in which they couldn't hit shots and the Thunder seemingly couldn't miss in building their largest lead in this series at 17 points. But the Grizzlies have yet to lose on their home court this postseason, and they won their third straight and seventh in eight games to grab a 3-1 lead in the series.
Game 5 is Wednesday night in Oklahoma City.
The Grizzlies outscored the Thunder 9-3 in overtime.
Kevin Durant scored 27 points but missed all five of his shots in the extra period, including a layup in the final seconds. Durant went 2 of 13 in the fourth quarter and overtime and had only five points. The All Star played 48 minutes and was just short on his shots as the game wore on.
Durant got the help from his teammates that he had been needing. Kevin Martin scored 18 points, Serge Ibaka had his best game of the series with 17 points and 14 rebounds, and Reggie Jackson had 15. Nick Collison even added 10.
Mike Conley led Memphis with 24 points and Marc Gasol and Zach Randolph each had double-doubles. Randolph had 23 and 12, while Gasol had 23 and 11 along with six blocks on the day the Defensive Player of Year was named to the NBA's second All-Defensive team along with Conley, who had four steals.
Allen, who finished with 10 points, had three steals on the day he edged LeBron James for most points for the NBA's All-Defensive team.
In 2011, the Grizzlies were the team that blew the big lead in the first half of Game 4 with the Thunder pulling out the win to even up the series. They also wasted home-court advantage last year in the playoffs in the opening round against the Clippers.
This time, the Thunder were up by as much as 17 in the first half and 12 in the third. But Memphis used a 20-8 run in the third to get back into this game. They blew a chance to close out the win when Ibaka blocked a shot by Randolph just before the buzzer in regulation.
But Allen scored to open overtime, then Randolph rebounded a miss by Marc Gasol and scored on a putback. Derek Fisher, who missed his first four shots, finally hit a 3-pointer. But the 38-year-old veteran also had his inbound pass stolen by Allen with 21.1 seconds left and Memphis up 100-97.
Memphis bounced back and outscored Oklahoma City 44-30 in the paint even though the Grizzlies got outrebounded 44-41. The Grizzlies still had a 13-8 advantage on the offensive glass leading to a 21-10 edge in second-chance points.
But they had no fast-break points compared to 12 for the Thunder. Memphis also took better care of the ball with only seven turnovers compared to 15 by Oklahoma City that the Grizzlies turned into 18 points. Memphis did not have a single turnover in overtime while the Thunder had two, including the one by Fisher.
The Thunder spent most of the past two days talking about the need to make shots. They did just that to open the game, hitting three of their first five in scoring the first seven points and led 29-18 at the end of the first quarter for their biggest lead in this series. Ibaka found his shooting stroke after struggling through this series, and he had nine points in the first 12 minutes, including a 3-pointer, with seven rebounds.
Oklahoma City had its biggest lead on a corner 3 by Durant that gave Oklahoma City a 46-29 lead with 4:26 left.
Memphis showed signs of life finally and finished the half on a 19-10 run that trimmed the Thunder's lead to 56-48 at halftime. Oklahoma City thought it had a double-digit lead when Ibaka beat the buzzer with a putback off a missed Durant 3. But officials reviewed the play and waved the bucket off.
