UFC Fight Night: Whittaker vs. Gastelum preview

Whittaker (22-5) has been on a roll since experiencing a rough 2019. That year, Whittaker first had to undergo emergency surgery for an abdominal hernia of the intestine and had to pull out of his fight with Gastelum in February. He then lost the UFC Middleweight Championship to Adesanya in the second round at UFC 243 in October.

Whittaker has been much stronger since and came back in July 2020 to post a unanimous decision win over Darren Till. He followed that up with a three-round unanimous decision win over Jared Cannonier at UFC 254 last October.

Gastelum (16-6) is happy to put an end to a nightmarish two-year span that saw him absorb three consecutive losses and a suspension. The first of those defeats was a unanimous five-round decision to Adesanya at UFC 236 for the interim UFC Middleweight Championship.

He also dropped a split decision, three-round bout to Till at UFC 244 and lost by submission to Jack Hermansson at UFC Fight Night: Figueiredo vs. Benavidez 2 in July 2020. He was then suspended by the USADA for nine months after testing positive for marijuana in relation to the Till fight.

Gastelum came back in February and posted a unanimous decision win over Ian Heinisch at UFC 258 and is hoping to be back on track. He is now looking to pull off the upset of Whittaker. You can only see who to back here.

UFC Fight Night: Whittaker vs. Gastelum predictions

We'll give away one of Parker's UFC Fight Night picks here: He is backing Lupita Godinez (-275) to defeat Jessica Penne (+235) in a women's strawweight bout. Godinez is off to a 5-0 start to her career after winning by decision over Vanessa Demopoulos at LFA 94 in October 2020.

Penne is 12-5 in her career with seven wins by submission, three by decision and two by knockout, but she has not fought in four years and has not won since 2014. "Godinez should be better everywhere in this fight and dictate the direction wherever she wants the fight to go," Parker told SportsLine.
