Unusual betting activity leading to the suspicion of match-fixing has increased according to the Tennis Integrity Unit.
The organisation that is trying to stamp out match-fixing in the sport claims to have received 48 alerts of unusual betting activity during the opening quarter of the year, which includes one set of suspicious activity from the WTA Tour.
This is an overall hike of 17 alerts in comparison to the first three months of 2015, and includes one set of suspicious activity during the Australian Open – the opening Grand Slam of the season.
The Tennis Integrity Unit (TIU) claims that the suspicions are primarily on the lower tier outside the WTA Tour, which comes to Eastbourne for the annual pre-Wimbledon Aegon International, and the ATP Tour meaning that Challenger and Futures competitions are being investigated.
The TIU has confirmed that a full investigation will follow if they are convinced that corruption was likely.
With around 100,000 professional matches completed annually, a mere 0.2% of these have caused betting companies to be suspicious.
The TIU was heavily criticised following a joint investigation by the BBC and BuzzFeed News alleged that 16 players who had been world ranked in the top 50 were suspected of fixing matches over the past decade.
Eastbourne Tennis made the local newspaper headlines in 2009 when the police wrongly suspected Eastbournetennis.com staff of being part of a Russian betting scam.
