Thursday's Antofagasta round of 16 pits Juan Carlos Prado Angelo against Pedro Boscardin Dias on clay. Juan Carlos Prado Angelo comes in at 6 wins from the last ten. Pedro Boscardin Dias has won 7 of the last 10.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. Angelo comes in off a compressed schedule; Dias comes in off a compressed schedule. This one is close to a coin flip, and the lean toward Angelo is exactly that — a lean.
