Doug Barron, Bhavik Patel and Scott Stallings have company. Mark Hensby became the fourth player suspended under the PGA Tour's anti-doping policy (that we know of). Curiously, Hensby was suspended not for a positive test, but rather for failing to provide a sample...which makes you wonder what the Australian has been up to. Someone get Robert Garrigus on the line... But really, it seems more likely, Hensby is done with professional golf, and didn't feel the need to provide a sample. No smoking gun here, necessarily.
