Breaks of 100 or more are called tons or centuries. They used to be very rare in
the old days. Now a lot of players make them regularly.
Stephen Hendry has made more than anyone else. His tally at
the moment is 309. 67 more than the number two, Steve Davis.
In the 1994/95 season Hendry amassed an incredible 53 centuries. That's the record for any player
for one season. Ronnie O'Sullivan is also an
impressive break-builder. After only three seasons as a professional he has cracked up 80 tons.
