The Tennis Integrity Unit, the anticorruption body that has come under increased scrutiny this year for perceived ineffectiveness and obfuscation, shed a sliver of light on its work Friday by publishing statistics about suspicious betting patterns over the first three months of the year.
The unit reported that it had received alerts from betting companies concerning 48 matches, which represents 0.2 percent of the 24,110 matches played in the first quarter of the year.
Of the 48 matches, one was at the Australian Open; one was at a WTA Tour event; 12 were at ATP Challenger events; 24 were at the lowest level I.
