The qualification period for the Ryder Cup is coming to an end, and there are only four spots left.

U.S. Open champion Wyndham Clark officially secured his spot on the U.S. Ryder Cup team on Monday, joining world No. 1 Scottie Scheffler. That leaves just four spots up for grabs.

Clark picked up his second career win on Tour at the U.S. Open earlier this year, which launched him up the Ryder Cup standings and into contention. Now, he’ll make his debut with the squad in the biennial event outside of Rome later this fall.

American golfers have until the end of the BMW Championship to earn one of the six automatic bids on the team. At that point, captain Zach Johnson will make his six captain’s picks to round out the 12-man team. European qualification is similar, but it runs through Sept. 3.
