Hingis earned $27,000 but played only two completed matches in her warmup for Wimbledon next week after a first round bye and a quarterfinal walkover.

Dragomir won the first two games before rain interrupted play. After the restart, Hingis won nine straight games with the Romanian No. 8 seed moving around the court with increasing difficulty.

Hingis continued to win easy points with Dragomir taking risks trying to hit early winners. The first set lasted only 23 minutes. Nine minutes into the second set, the match was over.

``I'm in pain,'' Dragomir said, apologizing to the center court crowd after pulling out. ``I don't want to take the risk of finishing this match and not being able to play Wimbledon.''

Rain halted the men's semifinals, and both will be completed Sunday before the finals.

Australian Patrick Rafter took a 5-2 lead in his first set against Czech Martin Damm, and fifth-seeded American Michael Chang and Nicolas Escude reached 2-2 before the rain stopped play for the day.
