PGA facing Monday finish after stormy Saturday

The US PGA Championship is in danger of stretching into a fifth day, at least, after thunderstorms prevented the leaders from even beginning their third rounds on Saturday.

Play was initially suspended due to the threat of lightning at 2:14pm local time (7:14pm BST) and it soon became clear that a lengthy delay was in prospect.

After almost four hours and with a number of puddles on the course, organisers eventually confirmed play would resume at 7am on Sunday, but it remains to be seen how much action will be possible with further storms forecast.

A tweet from the tournament's official account stated: "The final round will begin at 8:40am, staying in the same pairings as Round 3, starting from Tee #1 (approx. 8:40am-3:25pm starting times)."

The last time the US PGA was held at Baltusrol in 2005, Phil Mickelson prevailed in a Monday finish brought about by poor weather.

Leaders Jimmy Walker and Robert Streb, both nine under through 36 holes, are among 10 players yet to have teed off in round three.

They hold a two-shot lead over reigning champion Jason Day and Emiliano Grillo, with Open winner Henrik Stenson a stroke further back in fifth.

Prior to the storms rolling in at Baltusrol, there were plenty of birdie opportunities, with Kevin Kisner and Padraig Harrington among those to take advantage.

Both men went round in 65 to reach five and four under respectively, while Francesco Molinari finished his 68 with six successive gains to reach two under.
