MOSCOW — Russia's Ak Bars Kazan won the Kontinental Hockey League's Gagarin Cup for the third time in its history on Sunday with a surprise 4-1 series win over CSKA Moscow.

Ak Bars won Game 5 1-0, with ex-Edmonton Oilers wing Rob Klinkhammer scoring the winning goal on the power play early in the third period. Emil Garipov stopped 33 shots for the first shutout of the finals.

It was the first Gagarin Cup since 2010 for Ak Bars, which won the title in the KHL's first two seasons but hadn't won since.

Ak Bars was considered the underdog since CSKA's roster included eight of the Russian players who won Olympic gold in February, with Ak Bars having none.
