A spot in the next round is at stake on Tuesday, when Gabriel Diallo goes up against Tristan Boyer in the Los Cabos round of 32. Gabriel Diallo limps in on a 2-match losing skid, just 3 wins in 10. Tristan Boyer limps in on a 4-match losing skid, just 4 wins in 10.

This is the first career meeting between the two, which means no head-to-head baggage on either side of the net.

Diallo's 72.2% behind the first serve (against 67.5% for Boyer) means break chances should be scarce in one direction. The edge belongs to Diallo — real, but not the kind you take for granted at this level.
