Tony Finau enjoyed a spectacular second round at the Houston Open, shooting an eight-under 62 to open up a four-stroke lead on the chasing field heading into the weekend.

Finau was the joint-leader after the opening round, and he went even better in his second trip around Memorial Park Golf Course, sinking 10 birdies to go with two bogeys.

Fresh off his first PGA Tour season with multiple wins – including a career-high four top-two finishes – Finau is in prime position to make a run at his fifth title.

Alone in second at nine under is Patrick Rodgers, who followed his opening 68 with an impressive 63, as only he and Finau completed rounds of 63 or better before the weather arrived.

Joint-leader from the first round, Alex Noren is one further back at eight under, although he had three holes remaining when play was called off.

Noren is joined by Tyson Alexander, while China's Carl Yuan and America's James Hahn are the only players tied for fifth at seven under.

There is a seven-man logjam tied for seventh at six under, but Aaron Wise and Trey Mullinax will have their sights set higher before they begin their third rounds, with six holes still to play.

After a disappointing even-par 70 to open his week, world number two Scottie Scheffler is enjoying a five-under round through 13 holes, sinking an eagle on the par-five 12th right before his round was interrupted.

Former world number one Jason Day will likely see the weekend as he is tied for 37th at two under with six holes remaining, while his playing partner and former Masters champion Hideki Matsuyama is one further back sitting right on the edge of the cut-line.
