Ivanov retains heavyweight belt, Harrison, Magomedov win titles at WSOF 35

Blagoy Ivanov needed under two minutes to defend his World Series of Fighting heavyweight strap on Saturday.

The 30-year-old rocked challenger Shawn Jordan with a sneaky short left uppercut before sending him crashing to the canvas and finishing the job with follow-up punches to secure his third successful title defense 1:43 into the first round of WSOF 35's main event.

Ivanov won the title in his promotional debut with a third-round submission of Smealinho Rama in June 2015 and improved his WSOF record to a perfect 4-0 with the stoppage, while Jordan has split a pair of bouts - both of which ended by first-round TKO - in his brief stint with the Ray Sefo-led outfit.

The Bulgarian behemoth may have maintained order in his division, but the featherweight and bantamweight crops saw new champs crowned on Saturday's card, as Andre Harrison dethroned Lance Palmer for the 145-pound title by unanimous decision in the co-main event.

"The Bull" and Palmer engaged in a five-round striking battle, and while Palmer kept pressing forward and tagged Harrison on more than one occasion, the Long Island, N.Y. native swayed the judges with knockdowns in the first, second, and final round.

Harrison remains undefeated in 16 pro bouts, while Palmer - a two-time WSOF featherweight champ - sees his promotional record drop to 4-3 with the defeat.

In the evening's third title fight, Bekbulat Magomedov repeatedly took Donavon Frelow down to win all five rounds on the scorecards and claim the bantamweight title Marlon Moraes relinquished after fighting out his contract at the end of 2016.

Frelow kept looking for a home for his right hand, only for Magomedov to decipher his timing and put him on his hind parts every time he threw it. The Las Vegas product valiantly fought his way back to his feet and kept the damage to a minimum, but his resilience didn't do him any favors on the scorecards.

The 26-year-old Magomedov improved his WSOF record to 2-1 with his second straight decision win. Frelow, who filled in for an injured Timur Valiev on just 11 days' notice, is now 2-2 over a pair of stints with the promotion.
