Tennis: the Shanghai Masters
7–18 OctThe Shanghai Masters is wide open. It runs from 7 to 18 October, and world number one Jannik Sinner has withdrawn with a lingering knee injury. That has put Alexander Zverev in the frame to challenge for the top ranking.
ATP rankings dated 5 October show Sinner first, Zverev second and Alcaraz third. The full men's and women's top 10 tables are below, but I couldn't confirm the latest Shanghai results.

The men's tour has four levels. The four Grand Slams (Australian Open, French Open, Wimbledon, US Open) are on top, followed by nine Masters 1000 events including Shanghai, then smaller tournaments.
A match is played in sets, and a set in games. Within a game, points go 15, 30, 40, then game, and at 40-40 (deuce) a player must win two points in a row. Most tour matches are the best of three sets, and Slams are the best of five for men.
Rankings are based on points won over the previous 52 weeks, so injuries hurt twice: a missed event means missed points and a falling ranking.
