By far the most entertaining moment from last night's exhibition was the adorable shortie Juan Martin Del Potro pulled out of the stands. Many may have expected this little girl to be nervous under the pressure, however this little tike rose to the occassion and preformed very well. She was on her toes and hit consistently solid volleys, while smiling from ear to ear. Maybe we will see this mystery girl again in the future on the tour. That would certainly be a cool story to start a young girl's tennis career.
