10 slowest centuries in Test history by minutes played

#4 Sanath Jayasuriya 340 in 799 minutes against India at Colombo, 1997

Sanath Jayasuriya and Sri Lanka broke records in that Test match

The 1st Test of the series between Sri Lanka and India in 1997, turned out to be a totally pointless run fest but it saw one of history's longest innings from Sri Lankan opening batsman Sanath Jayasuriya.

On a pitch with nothing on offer for bowlers, India first piled up 537 but they might not have realized what lay in store for them as Sri Lanka kept batting till the fifth day. Much of that was due to the efforts of their left-handed opener, who batted for 799 minutes and faced 578 deliveries to score 340 runs.

It was an intolerably boring Test match but Sri Lanka smashed records and eventually declared for a world record score of 952.
