The opening round of Thursday's Arnold Palmer Invitational featured a jam-packed leaderboard at Bay Hill Club and Lodge in Orlando, Florida, but a true superstar finished alone at the top.
Jason Day carded eight birdies and an eagle during a six-under 66 to take the lead by one stroke over five other players. Notables among the pack at five under are Adam Scott and Henrik Stenson.
Day picked up steam on the front nine with four birdies in his first eight holes to offset a dropped shot at the par-three second. But adversity struck when, on an otherwise magnificent driving display, he yanked his tee shot at the par-four ninth out of bounds, leading to a double bogey.
