Schaeffler leveled 29-player field through 12 holes at 19-under

The third round of the US PGA's season-ending Tour Championship was

postponed Saturday after lightning struck an area on East Lake in Atlanta.

World number one Scotty Scheffler, the defending Masters champion,

led the 29-player field through 12 holes in the par at 19-under,

one stroke ahead of partner Xander Schöffle, the Tokyo Olympic champion.

The American pair were among 14 players who 

could not complete their third round due to the storm.

South Korean I'm Sung-Jae was third at 16-under with four holes remaining,

while four-time major winner Rory McIlroy of Northern Ireland

was fourth at 15-under and 5-under with 16 holes.
