Marquette's Helen Maroulis is among the favorites to win a medal in freestyle wrestling.

The top-ranked American women look to move one step closer to a first gold when they take on Serbia in the volleyball semifinals.

The landscape of the tournament changed after two-time defending Olympic champion Brazil made an early exit at China’s hands.

Serbia lost in four sets to the U.S. and Leland’s Alisha Glass during pool play, but pulled off a surprising five-set victory at last year’s World Cup in Japan that forced the Americans to qualify for Rio in January.

Here’s a look at the Michigan contingent in action (Team USA unless noted):

* Nate Brannen (Michigan): Track & field, 1,500 semifinals, 7:45 p.m.

* Alisha Glass (Leland): Women’s volleyball semifinals vs. Serbia, noon

* Adeline Gray (Marquette): Wrestling, freestyle (75kg) vs. Colombia’s Andrea Olaya, 9:16 a.m.
