Two-time major winner Dustin Johnson stormed up the leaderboard in the second round of LIV Golf Boston but Talor Gooch remains on top one stroke ahead of tour newcomer Joaquin Niemann.

Johnson responded from his opening-day 67 with a seven-under-par round of 63 to move within two strokes of the lead on Saturday at The Oaks.

The 38-year-old American's stand-out day included eight birdies and an eagle on the par-five eighth hole, along with three birdies. Johnson had claimed the outright lead with three holes to play before Gooch regained it.

Gooch, who shared the lead with Matthew Wolff after the first day on Friday, remains on top at 12-under, with Niemann one shot behind and Johnson's round moving him up to 10-under.

Wolff slipped four strokes off the pace after carding 69 for the day, while tour newcomer Cameron Smith also dropped back with a one-under-par round of 69.

Anirban Lahiri is outright fourth at nine-under, with Jason Kokrak carding a five-under-par 65 to move into equal fifth with Bernd Wiesberger and Wolff at eight-under overall.

Johnson's surge along with Gooch's excellent two days means Four Aces GC are top of the standings in the team element at 22-under.

Hy Flyers GC, captained by Phil Mickelson, are second at 19-under led by Wiesberger and Wolff. Mickelson is back at three-over overall ahead of Sunday's final round.
