Tennis predictions — Tuesday 20 October

The percentages are each player's win chance as the betting market prices it: every bookmaker's match-winner price with its margin removed (Shin's method), then the median across at least 3 books, exchanges left out. Player 1 is the first name listed. Spread and Total are in games, and Spread is player 2's line (−3.5: the market expects player 2 to win by about 3.5 games). Pred is the likeliest set score, with the player who wins it. It is worked out from the win chance, taking every set as a fresh contest at the same odds, over best of 5 sets at the men's Grand Slams and best of 3 everywhere else, and it is left out when the market's total games does not fit that format.
