Rousey considered a big favorite in potential Cyborg fight

As expected, UFC bantamweight champion Ronda Rousey will enter her third fight against Miesha Tate as a massive betting favorite.

Rousey (12-0), who is coming off a 34-second knockout against Bethe Correia at UFC 190, has opened as a minus-1,200 favorite over Tate, who comes back at plus-775. Both lines were set by Nick Kalikas of MMAOddsBreaker.com.

The two have fought twice before, in 2012 and 2013. Rousey won the first two meetings via armbar, although Tate (17-5) survived into the third round in the second fight. She is the only opponent to have made it out of the first round against Rousey.

"Over half of Ronda Rousey's career fight time has been against Miesha Tate," Kalikas said. "Even though I'm opening Rousey as a heavy favorite, I feel Tate has a better shot against Rousey than anyone else currently in the UFC women't bantamweight division."

Additionally, Rousey has opened a significant minus-450 favorite in a hypothetical fight against Invicta FC 145-pound champion Cris "Cyborg" Justino (14-1). Justino is listed at plus-360.

Justino is currently planning a drop to 140 pounds later this year, with the hope of eventually challenging Rousey for the bantamweight title in 2016.

The fight must take place on or before Aug. 1, 2016, and must be fought at 135 pounds for the betting line to apply. If the fight were to take place at a 140-pound catchweight, Rousey is a minus-325 favorite, with Justino a plus-265 underdog.

"Cyborg is perceived as the only true threat to Rousey's reign," Kalikas said. "She has been just as dominant in the women's 145-pound division as Rousey has at 135. This is more of your classic striker versus grappler matchup, despite Rousey's improvements on the feet. Due to concerns about whether or not Cyborg could make the 135-pound weight limit, I'm opening lines at 135 and 140-pound catchweight."

The UFC has stated previously the fight must take place at 135 pounds. The promotion currently does not promote a 145-pound weight class.
