On Thursday night, Invicta Fighting Championship touched down in Las Vegas to bring fight fans Invicta FC 13 live from Cosmopolitan of Las Vegas.

Undefeated inside the Invicta FC cage, featherweight champion Cristiane “Cyborg” Justino (13-1, 1 NC) headlined once again as she took on New Zealand’s Faith “The Immortal” Van Duin (5-1). Cyborg entered this bout having finished her last three opponents by TKO, the most recent coming at Invicta FC 11 when she stopped challenger Charmaine Tweet in 46 seconds. Van Duin made her promotional debut at Invicta FC 12 in April, submitting Amanda Bell in the second round.

The second of three title fights on the card looked to crown a new champion in the bantamweight division, as veteran Tonya Evinger (15-5) faced rising prospect Irene Aldana (5-1) of Mexico. Evinger entered this bout riding a six-fight winning streak, while Aldana had submitted her last two opponents in the first round.

Newly crowned Invicta FC Atomweight Champion Herica Tiburcio (9-2) of Brazil rounded out the night of title fights as she looked to defend her belt for the first time as she met Ayaka Hamasaki (11-1) of Japan in a bout that was originally slated for last fall at Invicta FC 9.


Amber Leibrock showed some impressive power in her Invicta debut against Marina Shafir. After some brief exchanges, a right hand dropped Shafir, who found herself unable to properly defend the barrage of strikes from Leibrock. The referee gave Shafir a chance to defend, but as Shafir held on to Leibrock’s leg and ate shots, the bout was mercifully called to a halt just 37 seconds into the first round.

Amy Montenegro and Jamie Moyle made for one of the night’s more close encounters, though fans knew this coming into the bout. Montenegro would pay for trying to clinch early on, as Moyle showed a solid ground game in the first round, but Montenegro would stay in the fight to the bitter end. Moyle would keep pressuring, not only striking with Montenegro, but also countering at every turn, though Montenegro would do the same in her own respect. Still, Moyle’s overall offense would net her a split-decision win, though it was by no means a one-sided affair.

Amber Brown never dialed it down against Catherine Costigan. She demonstrated everything from an intense flurry of liver shots to an attempt at an arm-triangle. Once she got he back, however, Brown flattened Costigan out, locked up a rear-naked choke, and forced the first-round tap.

From the moment her bout with Jessica-Rose Clark began, Pannie Kianzad turned up the volume on her striking and never really turned it down. When an opening for a takedown presented itself, Kianzad set it up nicely and worked to make something happen with it. All in all, Kianzad worked to fire off the cleaner techniques and make every shot count, and the end result went in her favor, as the unanimous-decision victory reflected all three rounds’ worth of the dominance Kianzad displayed.

A strong start arguably played dividends in a victory for Ayaka Hamasaki, who took some of the best offense that Herica Tiburcio could put together and still stayed relentless. Tiburcio certainly made the bout a close and fun encounter throughout the five-round duration, and she even had her moments where she seemed to have firm control of the bout. Despite that determination, and a third round that was razor-thin to where it became a headache to score, even for fans, Hamasaki persevered, made the most of the opportunities she had to take control of the bout, and while one judge favored Tiburcio, the other two saw the bout in favor of Hamasaki, who now gets to go home as the new Invicta atomweight champion.

The world knew Tonya Evinger wanted to become Invicta’s bantamweight champion, but what few expected came more in how she handled Irene Aldana so easily. From the onset, Evinger brought the fury to Aldana, beating down her foe to a point where most fights would have been stopped, but Aldana somehow managed to stick it out past the first round. Still, it didn’t stop Evinger from looking for any shot to get the fight to the ground and rain down with strikes from there, which she was able to do in the fourth round to claim the vacant crown.

At this point, the question is not so much about whether or not Cristiance Justino can be stopped in Invicta’s 145-pound ranks, but rather, how quickly she can stop her opponent. Faith Van Duin aimed to bring a challenge to the champion, but despite taking a right hand from Justino and getting off a nice kick, she at a brutal left hand, crashed to the floor, and was saved by the referee’s intervention after three furious right hands from the woman who retained her status as queen of Invicta’s featherweight division with the 45-second win on this night.
