What the Odds Actually Tell You
A tennis moneyline is a straight win-or-lose market on a single match. The minus figure shows you how much you need to wager to return $100 on the favorite; the plus figure shows what a $100 bet returns on the underdog. So -160 means risk $160 to net $100, while +135 means risk $100 to net $135. Oddsmakers set these lines using
surface records, head-to-head history, and recent form. When you open a match card in our sportsbook, the line also includes live movement as bets come in — so the number you see at match time may differ from the opening price. Factor that in before you lock anything in.
