Graeme McDowell and Matt Wallace sit four shots off the top of the leaderboard following the opening round of the Zurich Classic of New Orleans.
Foursomes was the format for the opening round that saw American pair Brice Garnett and Scott Stallings share the lead with Viktor Hovland and Kris Ventura on 10-under par.
McDowell contributed to his team's only bogey on the par-four 16th to go with their seven birdies.
Today will see teams play best-ball, with the lowest 33 teams and ties then progressing through to the weekend. Teams then play alternate shot again for Saturday's third round, with the fourball-style format returning for the final round.
Garnett and Stallings had five birdies each at TPC Louisiana, while Ventura contributed seven of the Norwegian pair's 10 birdies.
Englishman Justin Rose, hoping to make it third time lucky with Henrik Stenson of Sweden after previous tilts at the tournament in 2017 and 2018, had something to cheer about when he eagled the 554-yard 18th.
The Ryder Cup team-mates finished three strokes off the pace in 16th along with defending champions Ryan Palmer and Jon Rahm
Also sharing that spot on the leaderboard after rounds of 65 were England's Danny Willett and Tyrell Hatton, who both bogeyed the par-four 12th hole as their only blemish, as well as Scot Russell Knox and his American partner Brian Stuard.
