Tom Pernice Jr. got off to a terrific start in soggy conditions at the Mississippi Gulf Resort Classic.
In his first Champions Tour event this year, Pernice was 7 under through 12 holes before play was suspended because of darkness. The 52-year-old Pernice has played eight PGA Tour events this season.
Chien Soon Lu and David Eger - who won the inaugural tournament in 2010 - are one stroke back. Lu played 16 holes, and Eger completed 15.
Only a handful of players completed their rounds because the start of the tournament was delayed more than four hours after heavy rain fell on Fallen Oak in 36 hours.
Fred Couples was 3 under through 12 holes.
Defending champion Tom Lehman was even par through 11.
