“This is the first book I have seen that takes a fairly stat-heavy approach to trading in-game tennis. It explains in detail the single most important concept in tennis betting — relative hold and break percentages, which are used both pre-game and in-play for pricing. The author spends a great deal of time analyzing situations in-play that may have market inefficiencies. For example, how does a player do when facing a break-point at 0-40, compared to 0-30? Or how does a player’s play change when up or down a set? It also gives a lot of practical tips on the execution of trading. This book gets a lot of things right. If you read, understand and apply the contents of this book, you are likely to win (and at least not lose) betting in-play tennis.
