Unseeded Sam Querrey failed in his bid to regain the Queen's Club title he won in 2010 when he was defeated 6-3, 3-6, 6-3 by sixth-seeded Marin Cilic in the semifinals on Saturday.
Cilic will play the winner of the second semifinal between 10th-seeded David Nalbandian of Argentina and unseeded Bulgarian Grigor Dimitrov.
Playing in windy conditions, the American failed to win any of the nine break points in the 20-minute third game and was broken at love to leave Cilic serving for the opening set at 5-3.
After an early exchange of breaks in the second set, Querrey broke his Croatian opponent to lead 5-3 with a backhand volley and served out the set.
Cilic broke to lead 2-0 in the final set after Querrey stumbled to give his opponent break point and then double-faulted.
Querrey recovered the break at 4-2 but gave up his serve again in the next game by netting a backhand.
