OKLAHOMA CITY (AP) — Kevin Durant scored 18 of his 36 points in a scintillating final 7 minutes, Serge Ibaka added a career-high 26 points and the Oklahoma City Thunder evened the Western Conference finals at two games apiece by beating the San Antonio Spurs 109-103 Saturday night.

After seeing his team’s 15-point lead dwindle to four, Durant took over midway through the fourth quarter by scoring all 16 of the Thunder’s points during a span of just over 5 minutes to keep the Spurs at bay.

With All-Star teammate Russell Westbrook limited to seven points, Durant did almost all of the damage late to send the series back to San Antonio all square for Game 5 on Monday night.

Tim Duncan had 21 points for San Antonio, which had won 20 in a row before losing Game 3.
