Tuesday's Prague round of 32 pits Andres Martin against Filip Cristian Jianu on clay. Andres Martin is 4-6 across recent matches. Filip Cristian Jianu limps in on a 5-match losing skid, just 2 wins in 10.
The serve is where this match separates: Martin has been winning 68.2% of first-serve points to Jianu's 63.7%, and on clay that gap compounds fast. A tiebreak or two would surprise nobody, with Martin fractionally more likely to land the big points.
