England and Sri Lanka drew the third Test at Lord's on Monday. The result saw England take the three-match series 2-0 after convincing wins by an innings and 88 runs and nine wickets at Headingley and Chester-le-Street respectively.
But the two points gained for a draw were Sri Lanka's first in the inaugural multi-format Super Series with England.
Sri Lanka, on a rain-marred fifth and final day, finished on 78 for one after being set 362 for victory.
Dimuth Karunaratne was 37 not out and Kusal Mendis 17 not out, when the umpires finally called the game off at 5:12pm local time.
England's first innings 416 was built around Yorkshire wicket-keeper Jonny Bairstow's Test-best 167 not out and 85 from Cook.
Sri Lanka could only manage 288 in reply, despite fifties from openers Karunaratne and Silva, with all-rounder Chris Woakes taking three for 31.
England's second innings 233 for seven declared saw Alex Hales again fall short of a maiden Test century with 94 — his third fifty of a series where the Nottinghamshire opener had twice been dismissed in the 80s.
