Toronto Raptors big man Serge Ibaka just showed Golden State Warriors center DeMarcus Cousins how he earned the ‘Serge IBLOCKA' nickname.

Early in the second quarter of the NBA Finals Game 4, Cousins tried to do a power move against Ibaka under the basket. However, the Congolese-Spanish rim protector didn't budge and instead perfectly executed a huge denial to the delight of his Raptors teammates.

Ibaka has been sensational on the defensive end for the Raptors so far, and his block on Cousins is just one sample of what he has been consistently doing for the team.

In their Game 3 victory, Ibaka swatted six shots as Toronto bagged a convincing 123-109 victory. Remarkably, his six blocks is the most in the NBA Finals by any player coming off the bench.

The 29-year-old is undoubtedly a key cog for the Raptors, and the team needs him to anchor the defense if they want to take down the Warriors and bring the city of Toronto its first ever Larry O'Brien Trophy.

Heading to Game 4, Ibaka is averaging 8.3 points, 6.2 rebounds and 1.0 block in roughly 20 minutes per game in the playoffs. In the Finals against the Warriors, he is putting up 6.0 points, 6.0 rebounds, 1.3 steals and 2.3 blocks.
