Ireland's Shane Lowry maintained a one-stroke lead when play was suspended due to darkness on Friday midway through a weather-disrupted second round at the RBC Heritage in Hilton Head, S.C.
Lowry, who led by one after shooting a 6-under 65 in Round 1 on Thursday, reached 9 under while completing 16 holes at Harbour Town Golf Links before play was suspended at 7:47 p.m. ET.
Rain and thunderstorms halted play for 3 hours and 43 minutes in the afternoon before resuming at 4:31 p.m. Of the 130-player field, 56 were unable to finish Round 2, with two threesomes getting through just nine holes. The round will resume at 7:45 a.m. Saturday.
Lowry birdied his first two holes and added another at No. 5 before bogeying No. 7. After seven straight pars, he got back to 9 under with a birdie at the 15th.
Trey Mullinax holds the clubhouse lead alone after shooting a 3-under 68 to reach 8-under 134 for the tournament.
World No. 1 Dustin Johnson and Argentina's Emiliano Grillo are tied for third at 7 under after each shooting 67. Johnson opened on the back nine with two straight birdies and two more at Nos. 15 and 17 after a bogey at the 14th. He closed with a quiet front nine, with eight pars and a birdie at No. 8.
Grillo had the highlight of the day with an albatross, also known as a double eagle, at the 549-yard par-5 fifth, holing out from 254 yards on his second shot.
"It was perfect," Grillo said of the shot. "It was perfect distance. Perfect wind. It went in I think perfectly. It was one of those that I'll keep in my memory for a long time."
Slovakia's Rory Sabbatini (69) and Taiwan's C.T. Pan (65) are tied for fifth at 6 under, with a group of 11 players -- including three still on the course -- tied at 5 under.
