"Have the stretching exercises led to shaft changes with any clubs other than your putter?"

The Star-Telegram's Jimmy Burch asked Phil Mickelson about his growth spurt and other uh, shaft changes as a result of stretching.

What kind of stretching do you do to increase your height?

Just legs, low back, stuff like that. It has helped the elongation through motion. It's like a pitcher when he throws. He can't get his arm into certain positions statically when he throws a baseball. It's the same thing as using motion to stretch his length. It helped.

Have the stretching exercises led to shaft changes with any clubs other than your putter?

Not really. But my posture has been more consistent and easier to hold throughout the swing, so that's led to a little bit more consistent ball-striking.
