Australian Christian Sprenger, the 2012 Olympic silver medalist and 2013 World champion in the 100m breaststroke, retired, citing a 2014 shoulder injury and inability to compete at an elite level.
“I tried to get it back, but the power just wasn’t there, and I didn’t want to go to the Olympics to swim a heat,” Sprenger said, according to the Australian.
Sprenger, 30, also broke the 200m breaststroke world record in the 2009 World Championships semifinals (he would win bronze), keeping it until Hungary’s Daniel Gyurta broke it in the 2012 Olympic final.
