Tennis Betting Markets and the Retirement Rule
Match winner, set handicap and total games cover most tennis betting. The rule that catches people out is what happens when a player retires mid-match.
Tennis has no draw, so the match winner market is a straightforward two-way bet. Beyond that, the common markets are the set handicap, the game handicap and the total number of games in the match.
Handicaps and totals
A set handicap gives one player a start measured in sets, which suits matches where one side is heavily favoured but the scoreline may be close. A games handicap works at finer resolution. Total games markets ask whether the match will be long or short, and they are strongly influenced by serve quality on both sides.
Surface changes everything
The same two players produce different matches on clay, grass and hard courts. Clay slows the ball and rewards rallying, grass rewards serving. Break-point conversion and return points won differ so much across surfaces that season-long averages can be misleading when applied to a single event.
The retirement rule
If a player withdraws mid-match, sportsbooks do not all settle the same way. Some void bets unless a set has been completed, others pay out on the player who advances, and rules can differ between the match winner market and games markets at the same book. Read the tennis rules on your sportsbook before you bet, because this is the single most common source of disputes in the sport.
