What's at stake

A spot in the next round, prize money, and ATP ranking points hinge on the match outcome.

The match winner advances in the Tunis draw and the number of sets affects player fatigue and prospects later in the week.

Who's in play

Bernard Tomic serves aggressively and mixes slices; recent results show flashes of form but inconsistent match fitness.

Kimmer Coppejans builds points from the baseline and usually thrives in long rallies; his consistency pressures opponents in extended sets.

What drives it

Serve effectiveness, return accuracy, and unforced errors swing short matches quickly. A high first-serve percentage and few double faults favor straight-set wins.

Physical condition and recent match rhythm determine resilience in long sets. Weather and court speed change rally length and breakpoint opportunities.

What to watch

Before the match, check the official order-of-play and any late withdrawals or medical notices.

During play, track first-serve percentage, break points saved, and duration of the opening set; a long first set often signals three-set potential.
