Sri Lanka slumped after opening batsman Danushka Gunathilaka was given out for obstructing the field and lost by eight wickets to the West Indies on Wednesday in the first one-day international.
Gunathilaka made 55 and put on 105 in an opening stand with captain Dimuth Karunaratne, which seemed to put Sri Lanka on course to a commanding total after it lost the toss and had been sent in.
Karunaratne was out for 52, caught and bowled by West Indies captain Kieron Powell with his second delivery.
The match became ill-tempered when, in the 21st over, Gunathilaka was judged to have obstructed the field when he trod on the ball while Powell was attempting to affect a run out.
Powell bowled a short ball which Gunathilaka fended away. Pathum Nissanka set off for a single but Gunathilaka, after advancing down the pitch, sent him back and stepped back into his own crease. As he did so, he stepped on the ball and knocked it backwards.
Pollard immediately appealed and on-field umpire Joe Wilson gave a soft signal of out before television umpire Nigel Guguid ruled that Gunathilaka had deliberately attempted to foil the run out. There seemed to be little evidence the batsman had acted deliberately.
