Leader Rory McIlroy, Louis Oosthuizen, Tiger Woods and others are yet to tee off at the Deutsche Bank Championship at TPC Boston, but some big changes have already taken place on the tournament's leaderboard thus far today.
Among those on the rise in the standings, Keegan Bradley has made the most notable jump. He is storming up the leaderboard as he is five under through 12 holes on the day, putting him in a tie for 17th place overall, 50 spots higher on the leaderboard from where he began the day.
Also rising are Vijay Singh, Nick Watney and Carl Petterson, who have all improved to three under overall.
The most notable fall thus far today is Australian Geoff Ogilvy, who has fallen 28 spots into a tie for 66th overall. Ogilvy's fall is due largely to a double bogey on the par-5 second hole of the course. Also of note are Padraig Harrington and Graeme McDowell, who have both fallen into a tie for last place after shooting four over through 16 and 18 holes respectively.
McIlroy and Oosthuizen are set to tee off at 1:45 p.m. ET.
