Gonzaga All-Met golfer Keegan Boone birdied five of nine holes midway through his round in Tuesday’s Washington Private Schools Championship, including hitting a gap wedge that spun to within one foot on the par-4 No. 6. But it was a missed four-foot birdie putt on the 18th hole at Cattail Creek Country Club in Glenwood that left him disheartened.

The par on the final hole left Boone in a tie with Landon sophomore Brent Bubes, who got up and down from a sand trap on the 17th hole, then two-putted for birdie on the par-5 18th as each shot 4-under par 68 to share first place.

“I made a lot of real good shots, real good putts,” said Boone, who last week won the Washington Catholic Athletic Conference individual title and led Gonzaga to the team title. “In these two tournaments, that was probably the first putt inside six feet that I didn’t make. It was kind of heartbreaking.”

Bubes played bogey-free golf Tuesday, making birdie on the fifth, seventh and eighth holes then parring the rest until the final hole. While Boone’s approach shot on the 482-yard 18th was short and bounced off the lip of the bunker and threatened to go in a pond, Bubes reached the green in two.

As the players tallied their scores, coaches from the four participating schools met briefly before deciding not to hold a playoff.

“I got first definitely this way and you never know what would happen in a playoff,” said Bubes, who finished second in the Interstate Athletic Conference tournament. “It would have been fun, but it’s all right.”

The team competition was a runaway as Gonzaga capped its undefeated season by defending its title with a 32-stroke victory over Bullis and Landon.

Luke Malanchuk shot 69 for Gonzaga and Addison Coll also was under par, with a 71.

The first two girls to play in the event, sisters Olivia and Julia Bowling of St. Mary’s Ryken, shot 90 and 93, respectively.
