    Sebastian Korda: 88 serve, 90 return. Frances Tiafoe: 79 serve, 79 return. Sebastian Korda should hold serve with less trouble.

    Edge: Sebastian Korda

  3. Big-match pressure

    An ATP 500 semi-final, one win away from the trophy. Freshness counts now, and whoever has spent less time on court this week holds an edge.

What could change

What would change the King Exchange prediction?

Tennis calls move fast. These are the triggers the King Exchange desk watches.

  1. If a different player makes it to this round

    The call resets entirely. King Exchange updates the pairing as the draw unfolds.

  2. If Sebastian Korda survives a marathon in the previous round

    Fatigue would knock several points off the win chance, especially in a best-of-five.

  3. If conditions change (heat, wind or a closed roof)

    Quicker or slower conditions tilt the serve-return balance the call is built on.
