Three matches from this month's Wimbledon Championships will be investigated for possible match-fixing, the Tennis Integrity Unit has announced.
Alerts were triggered on two matches at the qualifying event at Roehampton and on one from the main draw at SW19, after some unusual betting patterns.
The matches will now be reviewed by the TIU along with one from last month's French Open, though the unit stressed that an alert is not evidence of match-fixing.
TIU have received 53 alerts since April - three from the men's ATP Tour and one from the women's WTA Tour. The rest came on the lower level Challenger, Futures and ITF Women's circuits.
In a statement on its website, the TIU said: "These will be assessed and reviewed in keeping with the TIU match alert policy below."
