Mickelson shrugs off injury to take part in this week’s Houston Open

Phil Mickelson has shrugged off a muscle injury and will be fit to play in this week’s Houston Open.

The American has been a major doubt for the event in Humble, as well as looking increasingly likely to join the ranks of the wounded alongside Tiger Woods by missing next week’s Masters at Augusta. However, the world number five, who withdrew from last week’s Texas Open with a pulled muscle in his right side, has declared himself fit to play the Houston Open.

"I played nine holes today at Augusta and I felt pretty good," the 43-year-old five-time major winner said on his official website.

"I was able to swing fine. It just felt sore as opposed to hurting. I feel that to give myself the best chance at the Masters I have to play in Houston.

"If I thought I would injure myself further I would have withdrawn from the tournament but the last few days have been good."

Mickelson will be one of 34 major winners teeing off at the Golf Club in Houston on Thursday. Rory McIlroy and Webb Simpson are also in the field, shaping the event up to be a good battle before the main event of the Masters at Augusta next week.
