Lefty has best chance to pass Woods
Mickelson can reach No. 1 for the first time in his career by winning at Pebble Beach. But there are more scenarios in Mickelson's favor.
He would go to No. 1 by finishing runner-up as long as Woods finishes out of the top four. Mickelson could finish third at the U.S. Open and go to No. 1 if Woods were to finish out of the top 18.
If Woods misses the cut, Mickelson would need no worse than a two-way tie for third.
Woods has been No. 1 for the last five years.
