Jermell Charlo defended his WBC Super Welterweight World Championship in dominant fashion with a devastating sixth-round knockout of mandatory challenger Charles Hatley in the co-main event of SHOWTIME CHAMPIONSHIP BOXING.
Charlo (29-0, 14 KOs) landed the crisper shots from the opening bell, using a sharp left jab to set up a remarkably efficient straight right. The Houston native Charlo, the younger twin of undefeated former 154-pound champion Jermall, floored Hatley (26-2-1, 18 KOs) midway through the third with a textbook left-right combo that stunned his fellow Texan.
Charlo's striking precision continued in fourth and fifth, before an onslaught of punches and a perfectly timed right to the chin sent Hatley falling face-forward to the canvas. Referee Harvey Dock didn't hesitate and instantly waved off the fight at :36 with Hatley out cold on the canvas.
The accuracy of Charlo's jab was telling - he landed his jab at a 31 percent clip to set up his power shots, which connected at an impressive 52 percent. Overall, Charlo landed 42 percent of his total punches over nearly six full rounds of prizefighting.
"I used that jab to set up the right hand," Charlo said. "I knew Charles Hatley goes down and he gets back up - he's a warrior - and I knew I had to get in there and be a lion.
"Hatley was moving around a lot. He was trying to engage and I tried to tell him to come fight. When he finally got in there, that's when I got him out. I'm the champ so I have to continue to fight my mandatory. They got a guy named Jarret Hurd that took my brother's title - we could unify."
Amanda Serrano became the first women and the first Puerto Rican to win world titles in five weight divisions with an eighth-round TKO of Dahiana Santana to capture the vacant WBO Women's Bantamweight World Championship in the featured bout of SHOWTIME BOXING on SHO EXTREME.
Serrano (32-1-1, 24 KOs) was the aggressor from the opening bell, moving forward and attacking with precision as Santana (35-9, 14 KOs) backed up and ate a steady diet of counter shots. Santana was deducted a point for clinching in the fourth, and had visible welts above both eyes following the seventh.
Serrano was connecting at an almost 3-1 power punch ratio when referee Benjy Esteves stepped-in to stop the bout at 1:14 of the eighth round.
"It means everything to me. We worked so hard. We worked hard for this moment," Serrano said. "To be a five division world champion is amazing. To be the first female and first Puerto Rican is amazing.
"I'm so proud to be a Puerto Rican. I'm so proud to be a SHOWTIME fighter. I'm just so happy for this moment. Just to be a five-division world champion, I could retire today and it'd be the happiest moment of my life. I'm just getting started. I hope I'm back again."
