All of the TOUR’s biggest names are back in action at this week's Arnold Palmer Invitational presented by Mastercard, the third Signature Event of the season.

Daniel Berger opened with a 9-under 63, grabbing a three-shot lead through 18-holes at Arnold Palmer's Bay Hill Club & Lodge. Collin Morikawa and Ludvig Åberg posted rounds of 66 and sit tied for second. Two-time Bay Hill champion Scottie Scheffler carded an opening-round 70 and sits seven shots off the lead. Rory McIlroy, the 2018 Arnold Palmer Invitational champion, shot an even-par 72 on Thursday.
