Serena Williams wrapped the day session at Arthur Ashe Stadium early on Thursday by easily doing away with Maria Jose Martinez Sanchez in straight sets during second round action, 6-2, 6-4.
Williams was efficient in the first set, winning six of the eight games in just more than 30 minutes. The second set, which took slightly longer at 48 minutes, saw Sanchez break Williams' serve once over the course of the match. Serena was able to manage.
Williams' 11 aces during the match helped bring her to 32 winners over the course of the 18 games. Her six double faults, however, might present a little pause moving forward for the fourth seed in the women's draw.
Sanchez was only able to create five winners during the match, but did keep her unforced errors low, collecting only 12 — seven of which were double faults.
Williams next will face Ekatarina Markova of Russia, currently ranked 42nd in the world.
