Cape Town - The Rebels heaped more misery on the struggling Reds by fighting back to grind out a 23-15 Super Rugby victory over the visitors, who had James Horwill sent off after 20 minutes on Friday.
Horwill and number eight Jake Schatz scored early tries to give the Reds a 12-3 advantage but the game turned when the Australian lock was shown a red card for striking Paul Alo-Emile.
The Rebels took advantage with lock Lopeti Timani, wing Tom English and scrumhalf Nic Stirzaker scoring tries as they picked up their third win of the campaign while ensuring the 2011 champions stayed bottom of the Australian Conference.
