Daughter's seizure on Mickelson's mind

When Phil Mickelson opened the Farmers Insurance Open with a 5-over 77 that left him near the bottom of the leaderboard at Torrey Pines, questions about the form of the world No. 15 were rampant.

The only question Mickelson wanted answered, however, was about the health of his daughter.

Mickelson's 10-year-old daughter, Sophia, underwent a series of tests on Thursday at a nearby San Diego hospital after experiencing a small seizure at school the previous Friday, according to Golf Central.

“It’s been a rough week,” Amy Mickelson said Friday, according to the San Diego Union-Tribune. “But you get through it. She’s been a trouper. She’s held up pretty well.”

Mickelson, whose wife and mother have both battled cancer in recent years, made a vague allusion to his daughter's condition after Thursday's round, saying, “I just wasn’t able to focus.”

The good news is that Sophia returned to school on Friday. Mickelson improved with a 4-under 68 on the easier North Course in the second round, but failed to make the cut for only the third time as a professional.

Mickelson will tee it up next week in the Waste Management Phoenix Open.
