Jessica Eye vs. Cynthia Calvillo preview

Eye's rise to the top of the UFC rankings is a testament to resilience and overcoming adversity. She made her UFC debut in October 2013 with a professional record of 10-1 following success stints in promotions such as Bellator and the North American Allied Fight Series.

She defeated Sarah Kaufmann by decision at UFC 166, only to have the result overturned to a no-contest because of a positive drug test. She then went on to lose five of her next six bouts while facing MMA luminaries like Miesha Tate and Sara McMann.

With her UFC career in jeopardy, Eye (15-7-1) went 3-0 in 2018, and her win over Katlyn Chookagian at UFC 231 put her in line for the title shot against Shevchenko. The 33-year-old Ohio native now needs a win against Calvillo in order to stay at the top of the rankings.

But Calvillo (8-1-1) has ambitions of her own. The Brazilian Jiu-Jitsu specialist has gone 5-1-1 in the UFC since her March 2017 debut, a decision win over Amanda Cooper. But her well-documented struggles to make weight at strawweight (115 pounds) has forced three of her bouts to become catchweight affairs and limited her ability to climb the rankings.

Even so, the 32-year-old California native hasn't lost since December 2017 and is looking to build off a standout showing in a draw against Marina Rodriguez in December. You can see Wise's full Eye vs. Calvillo picks here.

Top UFC Fight Night: Eye vs. Calvillo predictions

We'll share one of Wise's UFC Fight Night main-card predictions here: He is backing Karl Roberson (+175) to upset Marvin Vettori (-200) in a clash of middleweight prospects.

The fighters have animosity brewing because previous scheduled matchups against each other have fallen through for various reasons. A few weeks ago in Jacksonville, their bout was called off because Roberson missed weight and had to be hospitalized. A furious Vettori then tried to pick a fight with Roberson in their hotel lobby. "These two rising prospects hate each other. And I mean hate," Wise told SportsLine.

When they finally meet in the cage, Wise believes Roberson has the more polished skill set and is taking the underdog to get a stoppage victory. "Roberson is the better overall fighter and, in the smaller cage inviting more action, he should be able to finish Vettori," Wise said.
