BANDON — Dylan Wu and Kevin Murphy both saw their impressive runs in the 112th Pacific Northwest Men's Amateur Championship come to an end Tuesday afternoon.

BANDON — Dylan Wu and Kevin Murphy both saw their impressive runs in the 112th Pacific Northwest Men's Amateur Championship come to an end Tuesday afternoon.

Wu, a 16-year-old senior-to-be at St. Mary's, and Murphy, a recent Rogue River High graduate who is headed to Oregon State, triumphed in Round of 32 matches in the morning, then dropped their Round of 16 bouts later in the day.

Wu began the day with a 19th-hole victory over Kyle Schrader — thereby taking the "Giant Killer" moniker from the Olympia, Wash., player.

The Medford teen provided another gutsy effort in the afternoon before losing to Cameron Peck, also of Olympia, on the 20th hole.

Murphy defeated Bjorn Bjorke of Port Orford, Wash., in the morning, then fell to hot-starting Hans Reimers of Albany, 5 and 4. Reimers birdied five of the first 10 holes to go 5 up.

Both rounds Tuesday were on the Bandon Trails course. The tournament began with a 168-player field.

Wu was labeled the "Giant Killer" after beating Schrader, who was the last of 64 players to advance to match play, then knocked off top-seeded Joshua Munn in the first round.

Schrader, who plays for Western Washington University, immediately jumped out to a 2-up lead on Wu, but Wu drew even with a par and birdie on the next two holes.

"It was a pretty even match after that," said Wu.

They halved the next three holes before Wu took the lead for the first time with a 40-foot eagle putt at No. 9.

When Schrader drilled a 5-iron into the wind on the par-3 17th to win the hole for a 1-up lead going into the 18th hole, it didn't look good for Wu.

"I just told myself to relax and make birdie," said Wu. "I know that birdie's going to win this hole."

His approach shot was to within 15 feet and led to a match-tying birdie.

On the first extra hole, Wu left himself a 12-footer directly behind the hole — the same putt he had to start the match.

"So I knew which way it broke," he said. " ... Once I hit the putt, I knew it was going in."

The victory set the Northwestern recruit up against Peck, who last month won the Washington State Amateur and who had just defeated Nick Chianello, 3 and 2. Chianello is a recent Oregon State graduate and the two-time Oregon Amateur champion.

Peck, who recently completed his senior year at Texas A&M and was the 2008 U.S. junior champion, never trailed, but his biggest lead was only 2 up through six holes.

Wu pulled even with a par at 11, then they halved the next five holes. Peck went 1 up with a par at No. 16, then Wu won the 17th with a birdie. They each parred No. 18 to force extras, then did so again at No. 19 before Peck won the 20th with a birdie.

Murphy couldn't get anything going in his Round of 16 match against Reimers, who conversely was red-hot.

Murphy didn't make his first birdie until the ninth hole, but Reimers — who will be a senior at Mercer College and recently won the Oregon Open Invitational — had a 5-up lead going into it.

In the morning match against Bjorke, the Olympic College golf coach, Murphy broke away from an even match through seven holes with three birdies over the next seven holes to go 3 up.

Bjorke won the next two before a par at No. 17 sealed the victory for Murphy.
