A spot in the next round is at stake on Friday, when Alex Barrena goes up against Juan Carlos Prado Angelo in the Buenos Aires 3 quarterfinal. Juan Carlos Prado Angelo has won 3 in a row and 7 of the last 10 overall. Alex Barrena has won 8 of the last 10.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. Barrena comes in off a compressed schedule; Angelo comes in off a compressed schedule. This one is close to a coin flip, and the lean toward Angelo is exactly that — a lean.
