Rising welterweight star Jaron “Boots” Ennis aced the toughest test of his professional career with a sensational sixth-round knockout win over former world champion Sergey Lipinets in the main event on Saturday night’s SHOWTIME CHAMPIONSHIP BOXING telecast, live on SHOWTIME from Mohegan Sun Arena in Uncasville, Conn., in a Premier Boxing Champions event.

The win puts Philadelphia’s Ennis (27-0, 25 KOs) one step closer to his first world title opportunity as he dismantled the former 140-pound world champion over six rounds of their welterweight battle. As he has done often throughout his career, the 23-year-old switched effortlessly between an orthodox and southpaw stance and exhibited tremendous power from both sides. Ennis finished the fight with an eye-popping 53% connect rate on his power punches and out-landed Lipinets 91 to 48.

“I’ll always be hard on myself when I look back at my performance,” said Ennis. “My goal is to keep getting better, sharper, faster and stronger so I can become world champion. As long as I keep fighting top guys, I’m happy. I feel like I will be world champion by the end of this year or beginning of next year. Patience is the key though.”

The 32-year-old Joe Goossen-trained Lipinets (16-2-1, 12 KOs) of Woodland Hills, Calif., showed determination in weathering the onslaught of combinations from Ennis. An uppercut floored the Kazakhstan-born Lipinets and sent him to the canvas for the second time in his professional career in the fourth round. Prior to tonight, Lipinets had only been down in his other professional loss which came at the hands of four-division world champion Mikey Garcia.
“Lipinets has been in there with the best before, so I wasn’t surprised he held up for a while,” added Ennis. “I knew he’d be durable. That’s why I didn’t jump on the gas right away. I just took my time and broke him down.”

In the sixth round, Ennis poured it on Lipinets from all angles as he beautifully assembled combinations. The budding superstar has yet to go past the sixth round in his professional career as he has amassed a remarkable 89% knockout ratio. Ennis was up 49-45 on two scorecards and 50-44 on the final judges’ card prior to the right hook to left uppercut combination that resulted in the fight being stopped at 2:11 of round six.
