Men's Laser and women's Laser Radial wrapped up their opening series races on Saturday afternoon.
Gold medal favorite, Great Britain's Nick Thompson, finished two seconds ahead of current leader, Croatia's Tonci Stipanovic in race nine. Thompson sits in third overall.
Heading into the medal races on Monday, Australia's Tom Burton took over the second overall position from five-time Olympic medalist, Brazilian legend Robert Scheidt, who was second overall after race eight on Friday, but dropped to fifth overall after disappointing finishes in the day's last two races.
On the women's side, Gold medal favorite Marit Bouwmeester of the Netherland's, who was 10 points behind Denmark's Anne-Marie Rindom, proved why she was the heavy favorite to win gold. Bouwmeester overtook the lead and finished the opening series with 47 net points. Rindom has 55.
Ireland’s Annalise Murphy maintained the third overall position with 57 net points.
Evi Van Acker of Belgium, the silver medal favorite, improved from seventh overall to fourth after winning race nine.

American Charlie Buckingham did not advance to the medal race.
Team USA's Paris Henken and Helena Scutt won U.S. Sailing's first race of the Rio Olympics after a victory in race five of the 49erFX opening series.
The 49erFX, which made its Olympic debut in Rio on Friday, was even more exhilarating in race six. New Zealand's Alex Maloney and Molly Meech won the race, but Denmark, the Netherlands, Team USA, Spain and Brazil fought for the number two spot, with Denmark coming out victorious.
Heading into race seven on Monday, Denmark's Jena Hansen and Katja Salskoc-Iversen are in the lead, gold medal favorites and hometown heroes, Martine Grael and Kahena Kunze of Brazil are in second and France’s Sarah Steyaert and Aude Compan are in third in the fleet overall standings.

They didn't win any of Saturday afternoon's races but still hold the lead heading into race seven on Monday. Germany's Erik Heil and Thomas Ploessel are only three net points behind the Kiwis with 18.
The Americans keep on rising and strive for the podium.
Sunday proved to be a great day of racing for American men and women of the 470 class.
Team USA's Stuart McNay and Dave Hughes climbed two more spots and rose from eighth overall to sixth overall with 42 net points. They are 28 points behind leaders Sime Fantela and Igor Marenic of Croatia.
