With his second consecutive 5-under 65, Kuchar was at 10-under 130. DeLaet completed his second-round 67, even with three consecutive bogeys, before a two-hour weather delay just after noon Friday.
Kuchar was among 54 players who were unable to finish Friday night after play was suspended because of an approaching storm that brought heavy rain and lightning. Conditions were calm for the resumption of play.
Kuchar, No. 13 in the world and the highest-ranked player in the field, was on the green at the par-3 16th to start Saturday, and two-putted from about 40 feet for par.
