Ireland's Mark Power has battled his way into the quarter-finals at the Amateur Championship and kept the hopes of back-to-back Irish champions alive at Royal Birkdale.

Eliminating Englishman Jack Dyer in the morning tie, Power set up an afternoon showdown with German Marc Hammer, who last week emerged victorious at the Starnberg Open on the Pro Golf Tour. 

Earlier in the day, Hammer ended the hopes of Brabazon Trophy champion David Ravetto, defeating the Frenchman 2&1.

However, his winning ways were brought to a halt by Power who took control of the match early and was four up after five holes. 

It was a hard-fought battle between Power and Hammer with the German mounting a comeback to be just one down after 15 holes thanks to some impressive golf which included birdies at the sixth, seventh, 14th and 15th. 

Power also produced a birdie on the 15th to halve the hole, another at the 16th saw him go two up with two holes to play.

When the 17th hole was halved with pars, the Irishman sealed a 2&1 win. 

"I am delighted," Kilkenny 20-year-old Power said afterwards. "I knew it would be a tough one going out against Marc, he obviously beat a good player in David Ravetto this morning so I knew I would be up against it.

"James Sugrue won it last year and I play a lot of golf with him. When you see him win it, you are kind of jealous when you see him get to play in the Open and the Masters coming up. So, to get myself into a position to have a chance at doing the same is massive.

"When you see some of the big names who have won the Amateur it really shows what is possible."
