Bantamweight prospect Chantel Navarro had to pass a test in her first main event appearance in Las Vegas, Nevada. 

Navarro won a unanimous decision over Perla Lomeli in the main event from the Chelsea at the Cosmopolitan in Las Vegas. The scores were 79-73 twice and 78-74.

The bout was elevated to the main event after an IBF junior middleweight eliminator bout between Brandon Adams and Caoimhin Agyarko was called off the day before. 

Navarro, 22, started tense as the two fighters exchanged punches. The first round ended with a head clash. The two continued their 50-50 exchanges into the following round. Navarro targeted the body of the 25-year-old Lomeli, who pushed forward. Another head clash occurred in the third round, with Navarro getting a small cut over her eye. 

In the fourth and fifth rounds, Lomeli of Mexicali, Mexico, began to up her punch volume, appearing to outwork Navarro. Navarro’s right hand was also extremely accurate and eye-catching. 

Navarro fought a controlled tactical fight in her first scheduled eight-round bout, as Lomeli continued to throw, forcing Navarro to be judicious and accurate with her punches. The bout concluded with the two exchanging blows at close range. 

Navarro of Glendale, California, is now 8-0 (3 KOs). Lomeli falls to 7-8 (1 KO).
