Alvaro Quiros, the long-hitting tour pro from Spain, made a hole-in-one in Wednesday’s practice round at the Olympic Club. No big deal, right? Happens all the time on the PGA Tour, especially in practice rounds.

Not on a par-4.

Quiros aced the 288-yard, uphill 7th hole on the Lake Course. The ball landed on the front portion of the two-tier green, scooted up the slope and tumbled into the hole.

A short time later, we caught up with Quiros on the practice range. Not surprisingly, he happily re-lived the moment (his first-ever ace on a par-4).

“It was fun,” Quiros said. “My caddie and I were discussing 3-wood or driver. It looks like we picked the proper club. We hit driver and it found the bottom of the cup.”

Quiros and his group did not see the ball roll into the hole, given the uphill slope of No. 7. But they saw, and heard, the reaction of fans around the green.

“We didn’t see anything,” Quiros said. “People in the grandstands behind the green stood up and started screaming. We thought maybe it hit the flag.

“The U.S. Open is very exciting, but you don’t have a lot of chances to see great shots like that. Maybe on No. 7 and No. 17 here, where you have a chance at eagle. Apart from that, most of the time you are suffering.”
