The main event of the Strikeforce event on Saturday night at the HP Pavilion in San Jose, CA featured Nick Diaz defending his Strikeforce Welterweight Championship for the second time, this one against Evangelista Cyborg.

In what looked like a heavyweight boxing match for the first round and a good portion of the second, the pair traded blows. But things changed when Cyborg took Diaz to the ground. It turns out, that’s exactly what Diaz wanted to happen.

Diaz would take advantage of his Brazilian Jiu-Jitsu skills as he ended up beating Cyborg by submission (armbar) at 4:50 of the second round to retain his Strikeforce Welterweight Championship.
