Heavyweight contenders clash in the main event of UFC on ESPN 7 as veteran Alistair Overeem squares off against rising star Jairzinho Rozenstruik on Saturday night. The 12-bout UFC on ESPN 7 fight card takes place at Capital One Arena in Washington, D.C. The main card is scheduled for 9 p.m. ET, and preliminary bouts are set for 7 p.m. ET. The sixth-ranked Overeem (45-17-1) is a decorated UFC fighter and perpetual contender who is looking to improve his chances for another title shot with a win over a talented prospect. Rozenstruik (9-0), ranked No. 14, has won all three of his UFC bouts by stoppage. Overeem is a -120 favorite (risk $120 to win $100), while Rozenstruik is offered at +100 (risk $100 to win $100) in the latest Overeem vs. Rozenstruik odds. In the co-main event of UFC Washington D.C., Marina Rodriguez (-130) faces Cynthia Calvillo (+110) in a battle of top-10 women’s strawweights.

Marley won the first-ever “ToutMaster” UFC betting contest sponsored by MMAOddsBreaker and is in contention to win this year’s contest. He also appears regularly on multiple MMA betting and DFS shows. Over the past year, $100 bettors who have followed Marley’s UFC picks are up nearly $19,000. 

At the much-anticipated UFC 244 card last month, Marley told SportsLine members that Jorge “Gamebred” Masvidal (-140) would defeat Nate Diaz (+120) in a welterweight clash for the inauguaral “BMF” title. Marley argued that Masvidal’s boxing skills and power would be too much for Diaz, and he predicted a stoppage win for the slight favorite. He was proven correct when the bout was called by the doctor after the third round.

Marley knows the main event should be an entertaining bout because of the stakes for both fighters. The better-known name is the iconic Overeem, who might be in the twilight of his career, but believes he still has another title run left in him. Rozenstruik would like to climb the ranks by putting a well-known name on his resume. 

The 39-year-old Overeem is one of the most decorated heavyweights in MMA history. He has been in the UFC for nearly a decade and share the octagon with countless contenders. He is a former Strikeforce and Dream heavyweight champ, but has yet to wear the UFC belt. The Dutch fighter is 4-2 since losing a title bid to current champ Stipe Miocic in September 2016. He is coming off a first-round stoppage of Alexey Olenik in April. 

Rozenstruik, 31, is a last-minute replacement for the No. 8-ranked Walt Harris, who had to withdraw because of personal issues. The Surinamese fighter eagerly accepted the opportunity despite stepping into the octagon just over a month ago. He scored a first-round knockout over another savvy veteran, Andre Arlovski, in November at UFC 244 for his third straight stoppage win in the promotion.

We’ll reveal of one Marley’s UFC on ESPN 7 predictions here: He is backing Ricky Simon (+120) to pull the upset of Rob Font (-140) in the featured bout on the preliminary card. 

Simon (15-2) hopes to bounce back from his first defeat in the UFC, which came against the venerable Uriah Faber in July. Font (16-4) has split his past four bouts and took a decision victory over Sergio Pettis in his last fight.

“Simon puts up a crazy pace with his wrestling. Font doesn’t have great takedown defense, so I could see him getting taken down multiple times. Simon is a live underdog,” Marley told SportsLine.
