The Swedish golf star shot 68, three under par. This after four birdies and one bogey. It's three strokes better than the opening round at East Lake outside Atlanta.
But it could have been even better if he had had better distribution on the greens.
The 24-year-old is -8 overall after entering the competition as fifth on -5. He is tied for tenth place after the first two rounds.
American world number one Scottie Scheffler, who started the competition on -10, leads with a total of -21, four strokes better than second-placed Collin Morikawa, also from the USA.
The top 30 on the Fedex Cup ranking get to play the final, whose format has been debated before the competition. Scheffler got to start the competition on ten under par and the players were then ranked in descending order, with the lowest-ranked starting on par.
The winner takes home a check of approximately 255 million kronor (25 million dollars).
