Texas trainer with link to Pettitte may be key to Roger Clemens’ perjury probe

As the Washington field office of the FBI begins its investigation into whether Roger Clemens lied to Congress, two of the first people agents may want to interview are Kevin Schexnider and Kelly Blair, two men linked to the Texas gym that was a source of human growth hormone for Andy Pettitte.

Blair, a distant relative and former schoolmate of Pettitte, is listed in records as the owner of 1-on-1 Elite Personal Fitness, a Pasadena, Tex., gym. As the Daily News reported earlier this month, Pettitte told congressional investigators that his ailing father Tom picked up the human growth hormone at Blair’s gym and later passed it on to his famous son.

Sources told The News that Blair has been seen working out with Clemens’ son, Koby, now a minor league ballplayer, and that the Rocket had also been to the gym. Koby Clemens has not been linked to any illicit activity at the gym.
