Djokovic for sure looked a bit more energetic in the second set.
The fans gave Djokovic a loud ovation when he held serve to open the second set. The Serb looked up at the crowd and smiled while sipping water.After a forehand by Federer sailed across the baseline, Djokovic raised his arms, reared back and screamed. Now fully engaged in the match, he took the set to a tiebreaker.
Djokovic survived one match point and got one point away from taking the tiebreaker.
Federer ran off the last three points, closing it out with a forehand.
& here is the first reaction of Federer after winning his 5th Cincinnati Title

Here is the 2nd set stats
As you can see, this second set was a real close one & could have gone either way, but the one big difference between these two champs was Roger Federer's ability & the clever game-plan to approach the net as often as possible.
The way, he saved the set-point by approaching the net & then finishing the point with a great over-head smash was so praise-worthy.
As our own @FedererNews tweeted & I quote her,
"Roger Federer is divine when he approaches the net" & I couldn't agree more. For me, Roger is twice as dangerous when he approaches the net
