context_page_description: Casey Joel Stoner AM is a retired Australian professional motorcycle racer, and a two-time MotoGP World Champion, in 2007 and 2011.
  Stoner served as a test and development rider for Ducati from 2016 to 2018.
  Born in Southport, Queensland, Stoner raced from a young age and moved to the United Kingdom to pursue a racing career. After first competing internationally in 2002, Stoner became MotoGP World Champion in 2007 for Ducati. One of Stoner's greatest talents was his ability to ride any motorcycle beyond its perceived limits, even producing race wins on the inferior Ducati chassis after both Honda and Yamaha had forged ahead in development during his later racing years. Stoner won the MotoGP World Championship riding for Ducati and the win in 2007 remains as Ducati's only championship. During 2008 and 2009 Stoner remained a strong contender, winning multiple races, but not being able to consistently challenge Valentino Rossi and Yamaha for the title during those seasons. In mid-season of 2009, he even missed a few races due to chronic fatigue due to anaemia, having started the season strongly.
context_section_description: Stoner remained with Ducati for the 2009 season with new teammate Nicky Hayden, with a further option for a 4th season in 2010. A strong start to the season left Stoner in a three-way battle with the Fiat Yamaha duo of Rossi and Jorge Lorenzo, before he was struck by a mystery illness which caused him to feel tired long before the end of races, leaving him 16 points behind Rossi and 7 behind Lorenzo after the US Grand Prix at Laguna Seca on 5 July.
  Stoner was initially diagnosed with anaemia and an inflammation of the stomach lining. Stoner later disputed the diagnosis, however, and, after continuing to struggle with the condition, he announced on 10 August 2009 that he would miss rounds 11, 12 and 13 in Brno, Indianapolis and Misano, respectively, in an attempt to recover from the illness, he was subsequently diagnosed as lactose intolerant. Mika Kallio was chosen as Stoner's replacement for the three races.  Stoner returned to racing late in the 2009 season, placing second in the Portuguese Grand Prix and an emphatic first in the Australian Grand Prix, which he led throughout.  At interview following the Australian Grand Prix, Stoner said that he experienced none of the premature tiredness that had dogged him earlier in the 2009 season. He followed this up with another first place in the wet at the Malaysian Grand Prix. At the last round of 2009 at Valencia, Stoner dominated all practice and qualifying sessions to take pole, only to crash on cold tyres on the warm-up lap and miss the race. Stoner ended the season with four victories, and eight podiums in total, leading to a fourth-place finish in the riders' championship.
