Sportsbooks list Wilder as a -750 favorite (risk $750 to win $100), with Ortiz getting +450 (risk $100 to win $450) as the underdog.

Before you make any boxing predictions, be sure to see the latest Wilder vs. Ortiz picks from SportsLine's ultimate boxing insider, Peter Kahn.

A fight game veteran with over 20 years of experience as a manager, promoter and adviser, Kahn has his finger on the pulse of what goes on inside and outside the ring. He can be heard weekly as co-host of "The Fight Guys" podcast on the SB Nation Radio Network.

Nobody knows the heavyweight division better. For Wilder's last fight, in May, Kahn called Wilder knocking out Dominic Breazeale in the first round, a massive 22-1 long shot bet. "Based on everything Wilder has expressed leading up to the fight and his true dislike and beef with Breazeale, expect Wilder to come out and try to get rid of him early in order to make a statement," Kahn told readers. The result: Wilder ended it at the 2:17 mark with a violent one-punch knockout, and everyone who followed Kahn's advice cashed huge.

Now, Kahn has scouted Wilder vs. Ortiz 2 from every angle and locked in his picks, including one that pays a strong 8-1. He's sharing all of his Wilder vs. Ortiz predictions at SportsLine. 

Kahn knows that on paper, Wilder has plenty of advantages. He's six years younger than the 40-year-old Ortiz and has a three-inch height advantage and five-inch reach edge. Ortiz hasn't fought anyone in Wilder's class since their first bout, while Wilder has taken on Fury and Dominic Breazeale. In May, Wilder eliminated Breazeale with a vicious first-round knockout that went viral.

But just because Wilder is undefeated and won the first matchup doesn't mean he'll take down Ortiz on Saturday.

Ortiz says a lack of endurance caused him to wear down at the end of his March 2018 loss to Wilder. He hired a strength and conditioning coach, Larry Wade, and will enter the ring as a more chiseled, conditioned fighter. "To make it very clear, I wasn't knocked out," Ortiz told reporters. "I was completely fatigued." 

In the seventh round that night, Ortiz nearly finished Wilder. He came agonizingly close to becoming the first Cuban with a share of the heavyweight championship. Ortiz vows he won't run out of gas this time.

Kahn is confident he has the Wilder vs. Ortiz 2 winner, and he's also going big on exactly how long the fight lasts. You should see his best bets before you make your own Wilder vs. Ortiz predictions and picks.
