(Interim UFC Bantamweight Champion Renan Barao | Photo via MMA Weekly) By Elias Cepeda Interim Bantamweight Champion Renan Barao withstood some dangerous moments and an overall stiff challenge from Michael McDonald in the main event of the UFC on FUEL 7 card in England yesterday to retain his belt with a fourth round arm-triangle submission win. After three rounds of close action, that saw McDonald land some hard shots to the dome of the champion, Barao was able to drag the challenger to the mat, take his back and then quickly transition to a cross-side knee-on-belly position with a locked arm-triangle and force the tap. Throughout the fight, Barao looked confident on his feet but clearly wanted to take McDonald to the ground where he’d be safe from the American’s nasty counter-punches and where he assumed he’d have a clearer advantage. McDonald survived being taken down early in the first round and stuffed many more takedown attempts up until the end. Ultimately, the champion’s conditioning enabled him to continue to doggedly pursue McDonald and keep him on the mat. Barao earned an $50,000 with his Submission of The Night and urged injured regular bantamweight champ Dominick Cruz to come back as soon as possible, in his post-fight remarks. The win represented Barao’s 20th-straight victory, in a stunning streak that dates back to April 2008.
