New York: Seventh-seeded Francesca Schiavone needed just 53 minutes to advance to the third round of the US Open, beating Mirjana Lucic 6-1, 6-1 on Thursday.
The 2010 French Open champion had only one double-fault after committing 16 in her three-set first-round victory.
Schiavone did not face a break point and had only seven unforced errors, compared with 32 for Lucic.
The 96th-ranked player from Croatia, a former teen sensation, hasn't reached the third round at a Grand Slam tournament since 2001.
Schiavone will next face an unseeded opponent, Mona Barthel or Chanelle Scheepers.
