Each week, GolfChannel.com takes a look back at the week in golf. In this edition of After Further Review, our writers weigh in on the end (for some players) of anchored putting, Lorena Ochoa's hall-of-fame limbo and how the PGA Tour can ward off delays due to darkness.
The changing of the guard continues in the Official World Golf Ranking.
Last week, we saw Phil Mickelson drop out of the top 25 for the first time in nearly 20 years. The current leaderboard at the OHL Classic at Mayakoba features Russell Knox and Graeme McDowell at the top, two players whose rankings have been moving in opposite directions all year.
