The third major of the 2017 golf season is now underway and there is a familiar face on top. Jordan Spieth, the 2015 Masters and U.S. Open champion, is on top of the leaderboard after round two at the 2017 British Open at the Royal Birkdale Golf Club in Southport, England. Spieth, of Dallas, Texas, is currently at -6, and has a two stroke lead on reigning Olympic bronze medalist Matt Kuchar of Winter Park, Florida, and a three stroke lead over England’s Ian Poulter and 2017 U.S. Open champion Brooks Koepka of West Palm Beach, Florida. Third round coverage and fourth round coverage start on NBC at 4 a.m. Saturday and Sunday. Koepka and Poulter will tee off at 7:45 am PT and Kuchar and Spieth tee off at 7:55 am PT in round three on Saturday.

Here are the other events I will be watching this weekend:

Saturday—World Aquatics Championships—Water Polo—Women’s Playoff Round—Canada vs. New Zealand——8:30 am PT—Team Canada is now in the knockout stage in women’s water polo at the 2017 World Aquatics Championships in Budapest, Hungary. Team Canada finished pool play with a record of two wins and one loss in Group A action, and will face a New Zealand squad that went one win and two losses. Four times before Canada has earned a medal in women’s water polo at the World Aquatics Championships. They won silver in 1991 in Perth, Australia and in 2009 in Rome, as well as bronze in 2001 in Fukuoka, Japan and in 2003 in Montreal.

Saturday—CFL—Saskatchewan Roughriders @ Calgary Stampeders—TSN—6pm PT—The Saskatchewan Roughriders (1-2) will look to win their first road game of the 2017 Canadian Football League season as they face the Calgary Stampeders (2-1-1) at McMahon Stadium. The Stampeders find themselves in third place in the Western Division. That is very unfamiliar territory for the Stampeders in the John Hufnagel era as either the Stampeders head coach or general manager. Ever since Hufnagel joined the Stampeders as head coach, only once has Calgary finished any worse in the West than second place. That came in 2011 when Calgary finished in third place with a respectable record of 11-7.

Sunday—Rolex Grand Slam Equestrian Show Jumping——4:15 am PT—The first grand slam equestrian event of the 2017 season gets under way this weekend in Aachen, Germany. Canadian Olympic gold medalist Eric Lamaze of Montreal, Quebec will look to continue his momentum as he won the World Equestrian Festival in Aachen on Monday. Lamaze is currently ranked seventh in the world—behind Americans Kent Farrington and Mclain Ward, Italy’s Lorenzo De Luca, France’s Kevin Straut and Germany’s Daniel Deusser and Christian Ahlmann. Germany’s Philipp Weishaupt won the title in 2016.

Sunday—World Aquatics Championships——8:30 am PT—It is the first day of swimming finals from the 2017 World Aquatics Championships in Budapest, Hungary. The finals are the men’s and women’s 400m freestyle and the men’s and women’s 4x100m freestyle relay. Canada’s best chance for a medal will come in the women’s 4x100m freestyle relay, the event they won bronze at the 2016 Olympic Games in Rio de Janeiro.
