By Mark Lamport-Stokes (Reuters) - No one, and in all likelihood not even Tiger Woods himself, can know how the former world number one will fare as he makes his much anticipated PGA Tour return at this week's Safeway Open in Napa, California. After spending over a year on the sidelines while retooling his game following his recovery from back surgeries, Woods will be testing himself under the harsh glare of competition in three tournaments before the year-end. The 14-times major champion has not played on the PGA Tour since August 2015, having undergone surgeries in September and again in October of that year due to ongoing back problems.
