William Diering


William Grant Diering is a South African swimmer, who specialized in breaststroke events. He finished twelfth in the 200 m breaststroke at the 2008 Summer Olympics, and also set a new South African record to earn a bronze medal at the FINA World Short Course Championships few months later in Manchester, England.
Diering competed for the South African swimming squad, alongside his teammate Neil Versfeld, in the men's 200 m breaststroke at the 2008 Summer Olympics in Beijing. Leading up to the Games, he captured the men's 200 m breaststroke title at the South African Championships in Johannesburg with a new national record of 2:11.88 to assure his selection to the Olympic team under the FINA A-cut and shave 1.72 seconds off the standard previously set by Terence Parkin in 2000. Swimming in heat six, Diering threw down a new African record in 2:10.39 to grab the eighth seed for the semifinals, and then enjoyed his teammate Versfeld joining him to the roster by 0.11 seconds to round out the top four of their heat. Followed by the next morning's semifinals, Diering missed the top eight final with a twelfth-place time in 2:10.21, and lost a spirited challenge for another African record feat to Versfeld by just a small fraction of a second.
Shortly after the Olympics, Diering edged out Tunisia's Oussama Mellouli by nearly two seconds to claim the 200 m breaststroke title at the African Swimming Championships in Johannesburg with a time of 2:16.00.
