What's at stake

A win in Rome means a Round-of-16 berth and ATP ranking points that matter at Masters 1000 level.

Markets listed include outright match winner, game totals and set handicaps, so match length and set scores determine payouts across those markets.

Who's in play

Alexei Popyrin and Matteo Berrettini are the competitors; Popyrin is an aggressive big-server, Berrettini relies on heavy serve and powerful forehand.

Coaches, fitness staff and tournament conditions also shape outcomes, with Berrettini enjoying home support in Rome.

What drives it

Serve effectiveness, return pressure and short-ball exchanges influence whether sets run long or end quickly.

Other levers include clay comfort, recent match load, any lingering injuries, and weather-driven court speed that change probabilities for over/under and set handicap markets.

What to watch

Pre-match warmups and practice court footage will reveal serve speed and movement sharpness.

During play, track first-serve percentage, break-point conversion, tiebreaks, medical timeouts, and match schedule delays; the match start time and forecasted rain are immediate timing signals.
