Arnold Palmer Invitational presented by Mastercard Round 1

Daniel Berger delivered a stunning masterclass in the opening round, carding a bogey-free 9-under-par 63 to take a three-stroke lead. Berger, who has been working his way back from a broken finger late last year, caught fire on the back nine with six birdies, ultimately finishing nearly nine shots better than the field average. His performance was particularly impressive given the firm conditions that left many of the world's best struggling to find a rhythm. The chasing pack is led by Collin Morikawa and Ludvig Åberg, who both shot 6-under-par 66s. Morikawa surged late in the day with a dramatic eagle-birdie-birdie finish, while Åberg’s afternoon round was hailed as "unbelievable" by his peers given the intensifying winds. Defending champion Scottie Scheffler posted a steady 2-under-par 70 to stay within striking distance, but it was a difficult day for Justin Thomas, whose return to action resulted in a 7-over-par 79. By the end of Thursday, only 32 players managed to break par, underscoring the brutal difficulty of "Arnie's Place."
