One thing you should never do is count Claressa Shields out. Shields kept up her surprising charge through the middleweight bracket with a 31-12 victory over Andrecia Wasson.

The impressive 16-year-old built on her upset of Franchon Crews, the top American 165-pounder, a day earlier. Shields, a 16 year old Flint native, now advances to the U.S. Olympic Team Trials Finals on Saturday, February 18.
