The European Sports Security Association (ESSA) received more suspicious betting alerts for tennis than all other sports combined, according to the organization's quarterly figures.
Tennis accounted for 31 of the 37 alerts received in the third quarter, or 84 percent of all alerts. That is similar to the second quarter, and previous figures. Soccer was second, with three alerts.
Suspicious betting patterns can be an indication of match fixing, but can also occur for other reasons, such as injury or inside knowledge by bettors.
The Tennis Integrity Unit, which has sharing agreements with international betting companies, previously released its own figures, saying it received 96 suspicious betting alerts in the third quarter.
The organizations did not specifically define the criteria they use to decide if an alert is suspicious, and definitions can vary among betting companies.
The European Sports Security Association represents most of Europe’s largest betting companies.
