Raphael Collignon vs Grigor Dimitrov — R128 — Miami Open

Raphael Collignon, ranked #72, knocked off world #44 Grigor Dimitrov 7-6(3), 4-6, 7-6(8) by surviving the second-serve gap that should have sunk him — he won just 40% of those points to Dimitrov's 51%, and made up the difference everywhere else. Dimitrov's 23 aces and 50 winners never translated to control; his 44 unforced errors did. The decider hinged on game 10, where Collignon broke back to force a tiebreak he edged 10-8. Now 2-0 in the H2H, Collignon books a meeting with Flavio Cobolli.
