The 2012 Summer Olympics are just heating up and the competition across many of the sports is getting stiff.

Gabby Douglas, the gymnastics team favorite, landed the top spot for Thursday’s women’s all-around competition, finishing ahead of teammate Aly Raisman and beating out world champion Jordyn Wieber, according to the New York Times. Unfortunately, there are only two spots available per country. Wieber was devastated to learn she wouldn’t be moving forward to compete for the gold.

Douglas’ vault and bar routines were nearly perfect, earning 15.900 and 15.333 respectfully. But her floor exercise wasn’t as great. Douglas made a few small mistakes in her routine, even stepping out of bounds after a powerful flip. Her mistake forced judges to settle with the score of 13.766. Despite her mistakes, her overall score of 60.032 was high enough to land a spot for the all-around competition.

On the tennis front, Michelle Obama, Dominique Dawes and Venus Williams watched Serena compete in her first Olympic match against Serbia’s Jelena Jankovic, reports EURweb. Within an hour, Williams beat out her competition 6-3, 6-1. She’s well on her way to winning her first singles gold medal. Serena and Venus have previously won two gold medals for doubles competitions.

If Williams wins the gold medal, she’ll have completed the Career Golden Slam, where a tennis player wins four Grand Slam titles and an Olympic gold medal in a single year.
