American Cain out of world indoor championships
(Reuters) - American teenage middle-distance prodigy Mary Cain has withdrawn from the IAAF world indoor athletics championships in Poland due to a calf injury, U.S. officials said on Monday.
The 17-year-old U.S. women's 1,500 meters champion said in a statement she developed a discomfort in her lower calf over the past week and does not want to risk further injury. Cain will be replaced by Heather Kampf at the March 7-9 event,
