LAS VEGAS – David Benavidez didn’t get the vicious knockout he sought, but Benavidez battered and bloodied Caleb Plant throughout the second half of their 12-round fight Saturday night and decisively defeated his rival in their grudge match.

Plant and Benavidez embraced after their fight ended, which signaled a respectful conclusion to what was a nasty, years-long buildup toward their Showtime Pay-Per-View main event at MGM Grand Garden Arena. Plant boxed well during the first half of their 168-pound bout, but the relentless Benavidez’s power and pressure eventually wore him down and enabled Benavidez to produce a convincing victory on two scorecards.

Judges Steve Weisfeld (117-111) and Dave Moretti (116-112) scored nine and eight rounds, respectively, for the unbeaten Benavidez, who was slowed down at times by Plant’s excessive holding in the later rounds. Judge Tim Cheatham scored seven rounds for Benavidez, who won 115-113 on his scorecard.

“First of all, I want to thank this whole beautiful crowd for coming out,” Benavidez told Showtime’s Jim Gray in reference to the crowd of 13,865. “You guys made this happen. Second, I wanna shout out Caleb Plant. I know there was a lot said between us, but in the end we settled this like men. He’s a helluva fighter. I’m happy we gave the fans the best rivalry of the year or the last five years. I’m just very happy.”

Benavidez (27-0, 23 KOs), who was consistently listed as a 3-1 favorite, defended his WBC interim super middleweight title. The 26-year-old Phoenix native also maintained his spot as the WBC’s mandatory challenger for undisputed 168-pound champion Canelo Alvarez (58-2-2, 39 KOs), who will defend his four belts against English southpaw John Ryder (32-5, 18 KOs) on May 6 at Akron Stadium in Zapopan, Mexico.

The 30-year-old Plant (22-2, 13 KOs) lost for the second time in his past three fights. Alvarez dropped Plant twice in the 11th round and stopped him in their 168-pound title unification fight in November 2021 at MGM Grand Garden Arena.

The former IBF super middleweight champ came back impressively from his loss to Alvarez five months ago. Plant, of Ashland City, Tennessee, knocked former WBC champ Anthony Dirrell cold with a picture-perfect left hook in the ninth round of their October 15 bout at Barclays Center in Brooklyn.

Plant couldn’t hurt Benavidez with any of his punches Saturday night, though.

“David is a helluva fighter,” Plant said. “It’s a big rivalry, but that’s what boxing is all about. We came here and settled it like men. I take nothing from David. We haven’t been the best of friends, but we got into the ring and we settled it like men. That’s what you’re supposed to do.”

Plant’s cut above his right eye came from an accidental clash of heads during the eighth round.

“I got a head-butt, but it’s no excuse,” Plant said. “David was the better man tonight and I take nothing from him. Congratulations to him and his family. He’s a helluva fighter.”

Plant boxed his way to a lead on all three scorecards through five rounds.

Cheatham credited Plant for winning each of the first five rounds (50-45). Moretti (49-46) and Weisfeld (48-47) respectively scored four and three of the first five rounds for Plant.
