Surrey batsman Sangakkara had previously recorded hundreds against Lancashire and Warwickshire and struck two in their most recent Championship clash with Middlesex going into the first day of the four-day contest with Essex.
And his stunning form shows no sign of letting up after he closed on 177 unbeaten, honing in on a magnificent double-century.
Sangakkara’s innings has so far featured 23 boundaries, helping Surrey to 334-7 at stumps.
The 39-year-old retired from Test cricket in 2015, having racked up 12,400 runs, placing him fifth on the all-time list. He totalled 14,234 in one-day internationals and 1,382 in T20Is.
Domestically, Sangakkara now has 99 centuries, with 61 coming in first-class cricket and 38 registered in list A.
