Former caddie Steve Williams: 'No chance' Tiger Woods used PEDs

— -- Tiger Woods' former caddie doesn't believe all the weightlifting the golfer did has done him much good, but was adamant that he wasn't aided by performing-enhancing drugs.

Steve Williams, who caddied for Woods from 1999 to 2011 and was on the bag for 13 of Woods' 14 majors, said as much during a long "My Shot" interview for Golf Digest's July issue.

"Did Tiger do PEDs? There's no chance," Williams said. "Love him or hate him, Tiger always respected the game. He knows its history and people, its standing in sports and the world. He always knew what golf did for him personally.

The PGA Tour began random urine tests for PEDs on July 1, 2008, and so far there have been just two violations of the policy, and none from name players. The tour does not announce positive tests for recreational drugs.

Their breakup remains a sore spot for Williams, who said he was given the news over the phone; Woods was in the midst of a four-month injury layoff.

"Not hearing it from him face-to-face really bothered me," Williams said. "The suddenness of it, the way it was done, him coming out of the hardest time of his life and me having been loyal to him for so many years was worth some consideration. Caddies get fired all the time -- hey, Greg [Norman] fired me in 1989 -- but when you have what you believe is a friendship, it's going to leave a mark."

As for Woods' much-discussed workout routine, Williams said: "Tiger bulked up over the years. I spent the majority of my time with him on the course, so I'd only notice when I went months without seeing him. He always liked working out, and to a point it helped him, maybe more mentally than physically because of what exercise does to help your confidence and your thinking.

"As for his game, I'm not sure it helped him much, especially working with weights. Certainly he hit the ball farther when I first saw him than he did later."

Woods is playing this week's Memorial Tournament, where he has won five times. Williams will be back at work for Scott in two weeks at the U.S. Open at Chambers Bay.
