At the ATP Challenger $50,000 in Champaign, Ill., Michael Mmoh hit the deck during a critical break point opportunity against fellow American teenager Stefan Kozlov. He not only recovered almost instantly, but also won the point, and then served out the match. Only an 18-year-old would be able to get up that quickly.

The 6-1, 6-4 win put the No. 204-ranked Mmoh in the quarterfinals and extended his winning streak to seven (he won the Knoxville Challenger the week prior). Six of the quarterfinals in the Champaign draw are Americans.
