Keyshawn Davis scores late knockout over tough Jermaine Ortiz.

Keyshawn Davis announced his arrival in a new weight class in emphatic fashion, scoring a dramatic 12th-round stoppage of Jamaine Ortiz in the final seconds of their junior welterweight bout Saturday night at Madison Square Garden.

The co-main event to the Teofimo Lopez–Shakur Stevenson showdown marked a triumphant return for Davis following a turbulent 2025.

From the opening bell, Davis (14-0, 10 KOs) was in complete command, showcasing sharp ring IQ, a consistent jab, and punishing body work to steadily pile up rounds against Ortiz, who had never been stopped as a professional.

“I put on an amazing performance, like I promised you,” Davis said afterward. “I heard y’all booing, but I gave you a knockout. You just got to be patient.”

Ortiz (20-3-1, 10 KOs), who had previously pushed elite fighters like Teofimo Lopez and Vasiliy Lomachenko to the limit, was expected to provide a stern test in Davis’ 140-pound debut. Instead, he struggled to find any sustained offense and was systematically broken down by “The Businessman.”

Despite holding a sizable lead on the scorecards, Davis pressed for the finish. A crushing body shot sent Ortiz to the canvas in the 11th round, and Davis closed the show moments later, detonating a hard right hand followed by another brutal body shot to secure the late stoppage.
