(AP) - American 100-meter record holder Tyson Gay has tested positive for a banned substance and says he will pull out of the world championships next month in Moscow.
Gay isn't revealing the substance, but he says he was notified by the U.S. Anti-Doping Agency on Friday that a sample came back positive from an out-of-competition test May 16. He says he will have his "B" sample tested soon.
The 30-year-old Gay fought back sobs in a phone conversation Sunday from Amsterdam, saying: "I don't have a sabotage story. ... I basically put my trust in someone and was let down."
Gay was healthy again this season after being constantly plagued by hamstring and groin ailments, along with a surgically repaired hip. He won the 100 and 200 at nationals last month.

Tyson Gay was part of a six-man pool for the USA's 4x100m relay team competing at World Championships along with current Florida State sprinter Dentarius Locke. Locke has the fourth-fastest American time in the 100 meters this season, but with Gay now removed from the team, the Seminole is up to third-fastest.
Locke and Team USA are in Monaco this weekend training for IAAF World Championships, which will take place in Moscow August 10th through August 18th.
