Phil Mickelson had reason for optimism yesterday when he said doctors believe they discovered his wife's breast cancer early.

Amy Mickelson, who learned of the cancer last week, went through extensive testing this week.

"We have a wonderful team of doctors helping us, and it is believed that we caught this early," he said on his Web site. "We are anxiously waiting for a number of test results that will help guide us in the best possible direction."

Mickelson, the defending champion this week at Colonial, has taken an indefinite leave from the PGA Tour as he learns the extent of his 37-year-old wife's health.
