Jiri Lehecka vs Emilio Nava — R64 — Monte-Carlo Masters

Three hours and six minutes after he broke in the opening game, Lehecka finally pulled clear of Emilio Nava by leaning on the shot that decided everything: the second serve. The world No. 14 won 59% of his second-serve points to Nava's 41% — an 18-point gap that papered over Nava's 50 winners and let Lehecka absorb a second-set surge that included a saved set point and a match point before it slipped away in the Monte-Carlo tiebreak. Once the third set opened, Lehecka broke three times — games three, five and seven — to close it 6-2. Nava's 56 unforced errors were the through-line. Lehecka, a finalist in Miami a week ago, draws Alejandro Tabilo next.
