Phil Mickelson's Valero WD: Pulled Oblique

John Strege with quotes from Phil Mickelson following his Saturday WD at the Valero Open, citing a pulled oblique muscle.

Mickelson now faces uncertain status for next week's Shell Houston Open.

"My back's feeling great, my body's been felling great, I felt as good as I have all year," Mickelson said. "My speed is back, I was hitting the ball hard, driving it great. I pulled a muscle on my downswing trying to hit the ball hard on the second hole. It just killed and wouldn't subside for 10 or 12 seconds.

"I'm going to go back to San Diego for a couple of days and have a doctor take a look at it, but there's really not much you can do for a pulled muscle. I hope I'll be OK to play the Shell in Houstin, but I just don't know."
