Lagergren put his input on the par 5 hole with his third shot directly into the cup.
But that was not the only thing Lagergren did right.
He had five birdies on the yard and could write 67 in the scorecard.
He shares the lead with the Chinese Haotong Li.
Incidentally, there was no Swedish success on the first lap.
Only Krisoffer Broberg went in on red numbers, at -1.
For example, Henrik Stenson was noted for 77 strokes after two double bogeys.
