But it is not proof or evidence that corruption has taken place.”
Tennis was more evenly spread globally, led by Asia (19 cases), Europe (18) and North America (14).
For the whole year, soccer triggered 19 alerts while table tennis, ice hockey, snooker and greyhound racing each featured twice.
The ESSA report said that in the final quarter of 2015, there were 35 sporting events deemed to be suspicious with tennis accounting for 24 of them and soccer eight.
A top global bookmaker also suspended betting on a suspicious match at the Australian Open.
“All information supplied by betting operators is analysed by the TIU,” a TIU spokesman said in a statement.
Tennis governing bodies set up an independent review panel last month following media reports criticising the Tennis Integrity Unit (TIU) for not adequately investigating some 16 players repeatedly flagged over suspicions they had thrown matches in the past decade.
The organisation, established by regulated bookmakers to monitor suspicious betting patterns and guard against match fixing in sport, said 73 of the 100 events that raised concern involved tennis.
The review will take at least a year to investigate allegations of corruption in tennis and the effectiveness of existing procedures.
Geographically, 38 of the alerts originated in Europe, 24 in Asia, 16 in North America and 11 in South America. “The start of 2016 has seen a worldwide focus on alleged match-fixing in tennis,” wrote chairman Mike O’Kane in an introduction.

Match-fixing allegations by the BBC and online BuzzFeed News broke before last month’s Australian Open.
The spokesman added that factors that can influence results — such as player fitness, fatigue, form, playing conditions and personal circumstances — are analysed and if there are concerns about “suspicious activity” the TIU will investigate the matter.
Most of the cases of suspicious betting in soccer occurred in European matches. Africa accounted for nine. .
