Ronda Rousey knows all too well how to make people go from vertical to horizontal.
The UFC women's bantamweight champion showed just how superior her grappling game is in this new practice video filmed by BJPenn.com.
Such is Rousey's prowess at Judo throws and ankle picks that it almost seems unfair on her opponents.
At 11-0 and with 9 submission victories under her belt, it's hard to offer any genuine argument against Rowdy being the best grappler in the sport of mixed martial arts.
