Three games at this year's Wimbledon tennis championships were flagged for unusual betting activity, the sport's authorities have confirmed. Of these 53 alerts, however, three were on the ATP Tour and one on the WTA Tour.
Looking at this year as a whole, the cumulative six month match alert figure for 2017 is now 83, which is comfortably down on the 121 received for the same period in 2016. The other 45 were at low-level Challenger, Futures or ITF tournaments.
According to the TIU, 31,281 professional matches were played in the April-June period, meaning that the alerts comprised 0.169 percent of them. These will be assessed and reviewed in keeping with the TIU match alert policy.
