( CNN ) -- Taoufik Makhloufi stormed to gold in the 1500-meters , making the most of his reinstatement after initially being thrown out of the Olympics for not trying hard enough . The Algerian middle distance runner was expelled from the Games on Monday after the International Association of Athletics Federations ( IAAF ) said he did n't give his all in heats for the 800m . Makhloufi had tried to withdraw from the heat but did n't meet the deadline . He completed just 200m of the race before pulling out , prompting the IAAF to act . But after evidence submitted by a medical officer from the Games organizers , LOCOG , Makhloufi was reinstated and made the most of his reprieve by taking his first Olympic title . Day eleven of the Olympics as it happened . American Leonel Manzano grabbed the silver medal while Morocco 's Abdelati Iguider took bronze . Sally Pearson asserted her dominance in the women 's 100m hurdles by winning Australia 's first track and field gold of the 2012 Games . Pearson , the reigning world champion , set a new Olympic record time of 12.35 seconds , narrowly beating defending champion Dawn Harper of the United States while another American , Kellie Wells , claimed bronze . `` I do n't even know how to describe it because it 's like a dream right now , '' she told the host broadcaster . `` I really wanted this tonight , I 've worked so hard for the last two years . `` My goals were last year to win the world champs and this year to win the Olympic Games and I 've done that and I could n't be happier . '' Robert Harting won the men 's discus final with a throw of 68.18m to hand Germany their first athletics gold of the Games . The 27-year-old kept up his formidable record in the sport , having not been beaten in two years , and celebrated by jumping some of the hurdles that were on the track during his lap of honor .
