The current leader is Ryugi Imada, who missed only one green en route to a 62, tied with Martin Laird for the low round of the week.
Imada's previous best round on TOUR WAS 64 (three times, most recently in 2006). The 34-year-old, who has battled injury all year, secured his 2011 card last week when he tied for sixth at the Frys.com Open.
Imada was the focus of our PGA TOUR Insider this week .
