Marc Leishman is in a four-way tie for the Houston Open lead following an interrupted start at the PGA Tour event.

Play was suspended due to darkness on Thursday, with a number of players yet to complete their opening rounds in Houston.

Leishman – making his first Houston Open start since 2013 – got through his 18 holes and the Australian star carded a five-under-par 65 at Memorial Park Municipal Golf Course.

Russell Henley – winner of the tournament in 2017, Talor Gooch and Luke List are also five under, though the latter was the only member of the quartet still to complete his round, having made it through 15 holes.

"Probably for about six months I feel like I've been playing OK, just not getting anything out of it," Leishman said. "It can be a crazy game, it can get you down and you can play really well and not have a good score and play mediocre golf and have a really good score.

"You have to try and not let that get to you. I think a fresh season, a new start was pretty good for me. Got me to knuckle down and just really focus and been playing some good golf."

Jason Dufner is one stroke off the pace heading into Friday, while Keith Mitchell, Ben Silverman, Jhonattan Vegas (through 13), Wyndham Clark (through 13), Adam Long (through 11) and Martin Trainer (through 11) are a shot further back.

Former world number one Jason Day completed 11 holes to be even par before play was cut short, alongside four-time major champion Brooks Koepka (through nine).
