After a timid start, she took her chances and did not choke when it came to wrapping it up.
Garcia's loss means there are no French men or women remaining in the tournament. Her mother, Christina, is an attorney who gave up her practice for several years to move to Boca Raton in search of better training for her three tennis-playing daughters.
Thomas Hogstedt tells The Associated Press "it was a shock".
