The IBF Says Run It Back: Bustillos Gets Her Rematch With Sol Baumstarh Saturday in Buenos Aires

Yadira Bustillos left Buenos Aires in June convinced she'd won. Now the IBF is sending her back to prove it.

Bustillos (11-3, 2 KOs) of Las Vegas will face Maria "La Picante" Sol Baumstarh (15-7-1, 8 KOs) again this Saturday, Oct. 24, in Buenos Aires, Argentina, with the IBF interim minimumweight (105-pound) title on the line. Red Owl Boxing, which promotes Bustillos, announced the fight Monday. OR Promotions is promoting the show.

The IBF ordered the rematch after Bustillos's attorney, Tony Palmieri, petitioned the sanctioning body. His argument was simple: Bustillos should have gotten the nod in their first fight on June 5, a 10-round interim title bout in Buenos Aires that Sol Baumstarh won by split decision in her home province. Sol Baumstarh is from Brandsen, just outside the city.

"We are pleased to see that the IBF has taken decisive action and granted a rematch to Yadira Bustillos, who was arguably the victor of the first fight," Red Owl Boxing CEO Greg Bloom said in the release. "We hope that Yadira will get a fair shake from all officials assigned to work the rematch."

Read that last line again. That's a promoter telling you what he thought of the scorecards the first time.

The first fight was a war. Sol Baumstarh came out blazing and dropped Bustillos with a left hook to the chin early in the second round. Bustillos got up, went to the body and turned it around, and the two traded in close for most of the night until the final bell. Fights like that are why rematches get made, even without a petition.

Bustillos is 26 and, per Red Owl, ranked No. 5 in the world at 105. This is her third title shot. Before the first Sol Baumstarh fight, she lost a majority decision to Yokasta Valle for the WBC minimumweight title, and before that she'd won four straight, two by knockout. She's been close twice. Close doesn't get you a belt, and doing it in the other woman's hometown makes it harder.

Sanctioning bodies don't hand out rematches every time a camp grumbles about the cards, so the IBF granting this one tells you how that split decision sat. The tricky part for Bustillos hasn't changed, though. It's still Buenos Aires, and it's still Sol Baumstarh's crowd.
