Jiri Lehecka vs James Duckworth — R16 — Stuttgart Open

After dropping a 12-point opening tiebreak, Lehecka flipped the match on the only thing separating two near-even stat lines: break-point conversion. He took one of his two chances; Duckworth went 0-for-2 and saved just one of his own. The Czech's 41 winners to Duckworth's 20 carried him through, even on 57% first serves, and he closed a 140-minute fight with a 7-3 third-set breaker. In their first meeting — and first on grass — Lehecka's 15 aces and clean 2-of-2 break-point defense made the difference on margins this thin.
