LAKE BUENA VISTA, Florida (AP) - Luke Donald got off to a strong start in his pursuit of Webb Simpson and the top spot on the PGA money list, shooting a 6-under 66 Thursday in the opening round of the Children's Miracle Network Classic to share the early lead with five other players.

Simpson, who was paired with Donald, was two shots behind the leaders after a 68. James Driscoll, Arjun Atwal, Nathan Green, Gary Woodland and Scott Stallings all shot 66 for a share of the lead.

Donald, the world's No. 1 player, is trying to become the first golfer to finish the year No. 1 on both the European and PGA Tour money lists. He trails Simpson by $363,209.
