After a couple of dry weekends in boxing, there’s a flood of high-quality boxing matches on Saturday that will keep you busy handling your remote control. There’s Claressa Shields vs. Christina Hammer fighting in perhaps the most significant women’s fight ever. There’s a 50-50 matchup between former world titlists Caleb Truax and Peter “Kid Chocolate” Quillin. And junior middleweight standout Jaime Munguia returns to DAZN to defend his title.

(Plus, you might have seen Vasiliy Lomachenko destroy Anthony Crolla to defend his lightweight championship on Friday night).

Here’s a quick preview on each of the major clashes on Saturday.

Claressa Shields (8-0, 2 KOs) vs. Christina Hammer (24-0, 11 KOs), Showtime, 9 p.m. ET: In the biggest women’s fight since perhaps Laila Ali vs. Jacqui Frazier in 2001 or Ali vs. Christy Martin in 2003, Shields and Hammer are headlining a Showtime card to determine the undisputed middleweight champion. Hammer has more pro experience, and she’s held her 160-pound belt since 2011. Shields, the two-time Olympic gold medalist who won a super middleweight belt in just her fourth pro bout, hasn’t minded talking trash in the leadup. “When I beat Christina Hammer on Saturday, I want everyone’s headline to say ‘Shields nails the Hammer,’” the aspiring newspaper copy editor said. “It’s not a game to me. It’s going to be bad for her.”

Shields is a -300 favorite (and Hammer is a +230 underdog), and the German-born Hammer has to contend with an American crowd in Atlantic City. “I know that it’s a risk …” she said. “But I have done everything to bring it to her and break her down round-by-round. I want to show the people who the real champion is. A real champion fights everyone, all over the world. I’m very focused. I know that this is a historic fight. There is only one champion who can take these belts and that will be me.”

Caleb Truax (30-4-2, 19 KOs) vs. Peter Quillin (34-1-1, 23 KOs), FS1, 9 p.m. ET: When Quillin was preparing for his world title shot vs. Hassan N’Dam in 2012, he and Truax sparred for a few days in training camp. Seven years later, Truax told Quillin to his face that those sparring sessions gave him confidence that he would get the better of Quillin when they fought for real (for the record, Quillin said he doesn’t put much stock in those sparring results). “I came away feeling confident that if we ever fought, I'd be able to get the job done,” said Truax, who’s a +205 underdog and who admitted that a punch from Quillin seven years ago knocked his headgear across the gym. “I don't remember much of the specifics, but I felt confident from the experience. At the same time, I'm expecting an even better Peter Quillin on Saturday night and that's what I trained for.”

There’s little doubt both fighters need a win. Quillin, the -265 favorite, is still recovering in boxing fans’ eyes from his first-round knockout loss to Daniel Jacobs in 2015. Truax upset James DeGale to win his super middleweight title in 2017, but then he promptly lost it in the rematch, and considering he’s 35, he needs a win to make one last run at another belt. Quillin, meanwhile, has to contend with fighting in Truax’s home state of Minnesota. “I have a very determined opponent and I'm fighting in his backyard. It's a tough fight for both of us,” Quillin said. “I have to put my authority down on this fight and control it. It's going to be hard with all his fans in there, but what I've always done is take negative circumstances and turn them into positives.”

Jaime Munguia (32-0, 26 KOs) vs. Dennis Hogan (28-1-1, 17 KOs), DAZN, 7 p.m. ET: If you don’t think Hogan has much of a chance to beat Munguia, who happens to be a huge -5000 favorite (meaning you'd have to wager $5,000 to win a paltry $100), you’re probably right. When he faced Jack Culcay, the biggest test of his career, in 2015, Hogan lost a relatively wide unanimous decision. Say what you will about the fact Hogan is now Munguia’s mandatory opponent, but he’s grateful for the opportunity. “I want to say that as an Irish man living in Australia who is fighting a Mexican in his own land, I am honored,” he said. “I know that Ireland, Australia and Mexico are great boxing nations with people who always fight with determination and will. So, I know this will be an excellent fight for everyone in the world.”

For as long as it lasts, perhaps. But Munguia is a power puncher that delivers plenty of pressure to his opponents. Hogan might have a difficult time withstanding it, especially if Munguia is especially fired up to perform in front of his fans in Mexico. “It’s a big pressure because everyone wants to see me win by knockout,” Munguia said. “But the truth is I need to stay calm. Sometimes I can’t get the knockout, so I have to maintain my calmness.”
