LONDON (Reuters) - Matches at Wimbledon and the French Open triggered alerts for potential match-fixing in the second quarter of the year, the Tennis Integrity Unit (TIU) said on Wednesday.
It said in a statement that one match at Roland Garros and three at Wimbledon, two of them in the qualifying tournament and one in the main draw, would be assessed and reviewed.
Alerts are raised in response to unusual betting patterns, which are not in themselves evidence of match-fixing and can be due to a number of other factors, including conditions and player fitness.
The TIU said 40 of 53 alerts received were for matches played on the lower level men's ATP Challenger and ITF Futures circuits.

Three were on the men's ATP Tour, one on the women's WTA Tour and five on the ITF women's circuit.
During the April-June period, 31,281 professional matches were played. The cumulative six month match alert figure was 83, compared to 121 received for the same period in 2016.
