Big new signings hit the ground running in the first round of LIV Golf Boston, but after 18 holes at The International Golf Club it is Matthew Wolff and Talor Gooch tied for the lead at seven under.

While Gooch got to his 63 in a traditional fashion, posting eight birdies and one bogey, Wolff had far more ups and downs, making up for his three bogeys with six birdies, an eagle and a hole-in-one – the first ace in LIV Golf history.

One stroke behind the leaders are new arrivals Cameron Smith and Joaquin Neimann, after both played in last week's PGA Tour Championship.

Smith had five birdies and two eagles, showing off his firepower, but a double-bogey on the par-four 14th hole cost him a chance at the first-round lead.

After his round, Smith called it "great fun" and said "it was nice to see a familiar face" about his pairing with Dustin Johnson.

The rest of the field is at least two further strokes back, with Kevin Na, Bernd Wiesberger, Louis Oosthuizen, Paul Casey and Anirban Lahiri occupying the tie for fifth at four under.

The logjam at three under includes Dustin Johnson and Pat Perez, who along with Gooch and Patrick Reed (one under) have their Four Aces GC sitting second in the team standings. They trail only Hy Flyers GC, consisting of Wolff, Wiesberger, Cameron Tringale (one over) and Phil Mickelson (four over, 45th out of 48).

Bryson DeChambeau and Carlos Ortiz are at one under, and the Koepka brothers – Brooks and Chase – shot even-par 70s.
