The Farmers Insurance Open has a less star-studded field this year, with notable withdrawals including Collin Morikawa and Will Zalatoris.

To avoid conflicts with NFL conference championship games, the Farmers Insurance Open is scheduled to run from Wednesday to Saturday.

The 25-year-old Swede excelled on the easier North Course, hitting 16 of 18 greens in regulation, with eight birdies and one eagle.

Danny Walker, in his fourth PGA Tour start, recorded a bogey-free round, finishing the day just one shot behind Åberg.

Walker is tied for second place with Hayden Springer, both finishing one shot ahead of Lanto Griffin, Zac Blair, Zach Johnson, and Aldrich Potgieter.

Aberg leads the tournament by two strokes over Walker and Springer, with Walker being the only top-seven player on the tougher South Course.

Ludvig Åberg shot an impressive 9-under 63 in the first round of the Farmers Insurance Open at Torrey Pines, taking a two-shot lead and marking his best opening-round score on the PGA Tour.

Åberg expressed his love for Torrey Pines, calling it 'my favorite place in the world,' and is excited about the potential for the Genesis Invitational to be held there in three weeks.

Zach Johnson, competing on a sponsor's exemption, made a strong start at Torrey Pines, despite not having won since the 2015 British Open.

The South Course had a higher scoring average of 72.487 compared to 70.218 on the North Course, contributing to the challenges faced by players.

The location for the 2025 Genesis Invitational remains uncertain after its previous venue, Riviera Country Club, was affected by wildfires.

Streaming of the tournament is available via PGA Tour Live on ESPN+, with simulcast coverage on NBCSports.com and the NBC Sports App.
