2024 Zurich Classic leaderboard, scores: Rory McIlroy, Shane Lowry among leaders after Round 1

McIlroy and Lowry headline a crowded leaderboard as the competition moves to foursomes for Friday

There aren't many firsts left for Rory McIlroy to achieve in his PGA Tour career, but he checked one off the list Thursday at TPC Louisiana. Making his debut appearance in the Zurich Classic, the 34-year-old looked like the seasoned veteran he is alongside Ryder Cup teammate Shane Lowry. The two fired an 11-under 61 in the four-ball format amid the windy afternoon conditions to sit with the teams of Ryan Brehm and Mark Hubbard, Aaron Rai and David Lipsky and Ben Kohles and Patton Kizzire atop the leaderboard after Round 1.

While this week marks McIlroy's first attempt at claiming the PGA Tour's annual team event, it also represents his 11th start of the year as he continues to play through some relative early season struggles. McIlroy had no issues in the first round as he drove the ball beautifully, struck towering iron shots and picked apart the par-72 layout in unison with Lowry.

"You know that you sort of need to get off to a good start, and thankfully we did," McIlroy said. "We were 4 under through 4, which was really nice to see, and from there you've got some momentum and you're just trying to keep it going. But for the most part today, we kept both balls in play. We were having two looks basically on every hole at birdie, and that's the way you need to play better ball. Everyone thinks it's maybe a bit more gung ho than that, but as long as you have two balls in play off the tee, two balls on the green, I think you're always going to do pretty well in this format."
