A spot in the next round is at stake on Tuesday, when Pablo Carreno Busta goes up against Vilius Gaubas in the Estoril round of 32. Pablo Carreno Busta comes in at 6 wins from the last ten. Vilius Gaubas is searching for form, having lost 2 in a row (2 of the last 10).
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
Busta's 68.1% behind the first serve (against 64.8% for Gaubas) means break chances should be scarce in one direction. Gaubas needs several things to break right at once; the percentages say they usually don't.
