Third-ranked Rory McIlroy and England's Paul Casey made early charges Friday but American Roberto Castro remained in the lead after the storm-interrupted first round of the US PGA Tour BMW Championship. Castro, seeking his first PGA title after two runner-up efforts, opened with a seven-under 65 Thursday at Crooked Stick in Indianapolis to lead compatriot Brian Harman by one stroke. US major winners Dustin Johnson, the world number two who won the US Open in June, and Jason Dufner reached the clubhouse on 67 Thursday before darkness fell.
