UFC welterweight champion Georges St. Pierre and top contender Jake Shields battled in UFC 129 Saturday night at Rogers Centre, as the champ retained his belt in a relatively easy victory in a unanimous decision.

Fighting in his home country, and in front of more than 50,000 fans, most pulling for the Quebec-born champion, GSP used his jab and his overhand right to secure the win.

Round One saw St. Pierre land a nice straight left and overhand right, as he was connecting more as the round came to a close.

The second round was more of the same, as St. Pierre used his jab and his overhand right to put Shields on the defensive.

In Round Three, St. Pierre delivered a takedown with 20 seconds remaining, while Shields barely made much of an impact when he needed a big round.

Round Four saw St. Pierre out of nowhere land a head kick that staggered Shields.

In the final round, neither fighter landed much of anything, but St. Pierre still was more commanding.

It was an odd fight, as Shields did little to prove he wanted to be the aggresor and showed no desperation when the fight was clearly one sided. Perhaps the only drama to the fight was that St. Pierre couldn't see from his left eye since the second round.

Also puzzling was how two judges scored the fight 48-47, when it seemed that only the fifth round could have possibly been given to Shields.

At the weigh-in, Shields, a California native, was confident that he could pull off the upset.

I am bringing the belt home, said Shields. The crowd can boo me all it wants. It will only be me and him in the cage.

That wasn't the case, as GSP was just too much for him, and Shields didn't appear to be fighting with any real strategy.
