Scottie Scheffler maintained a commanding lead at the Tour Championship with a 5-under 66, bringing his total to 21-under par after two rounds. However, Collin Morikawa surged with an impressive 8-under 63, reducing Scheffler's lead to four shots, while Xander Schauffele remained in contention with a 64. Morikawa's performance included nine birdies, showcasing his aggressive strategy despite the significant deficit. Scheffler, the No. 1 seed, acknowledged the challenges posed by his competitors and the firm conditions of the course. With a $25 million prize at stake for the FedEx Cup winner, Morikawa and Schauffele are determined to close the gap. The tournament atmosphere intensified after a weather delay, adding urgency to the competitors' efforts.
