PITTSBURGH (AP) — A downpour has halted second-round play of the Senior Players Championship until Saturday.

The thunderstorm Friday afternoon dumped a half-inch of rain on Fox Chapel Golf Club in 30 minutes, overflowing creeks and turning fairways into small ponds.

Fred Couples leads the tournament at 11-under. He is 7-under through 11 holes of the second round.

John Huston is second at 9-under. The first-round leader holed out from the rough on No. 15 just before officials stopped play.

Jeff Hart shot a season-best 5-under 65 and is the leader in the clubhouse at 7-under. Only 15 of 81 players in the field completed their rounds.

Officials said the threat of another storm later Friday led to the decision to stop for the day.
