Mardy Fish set up an all-American final an the Queen's Club grass-court tennis event with a 6-3 6-4 straight sets win over Spain's Feliciano Lopez.
Fish, serving powerfully, defeated Lopez easily with the eighth-seeded Spaniard unable to reproduce the form that had seen him defeat compatriot Rafael Nadal, the world number one and French Open champion.
Fish will now face fellow American Sam Querrey, a friend, in the final on Monday.
Earlier the 1.98m tall Querrey defeated Germany's Rainer Schuettler 6-7 (9-11) 7-5 6-3.
This year's Queen's final will produce a surprise champion after a week of upsets that have seen defending champion Andy Murray, Andy Roddick, Novak Djokovic and Nadal all knocked out at the south-west London venue earlier in the week.
