Afghan Voice Agency(AVA)_Monitoring, Having amassed a target of 324, the Sri Lankan bowlers skittled out the tourists for 191 inside 43 overs for their biggest win in ODIs over Afghanistan, AFP reported.
Quick bowler Dushmantha Chameera, returning to the side after a seven-month layoff after ankle surgery, bowled a couple of hostile spells to finish with two for 18.
Sri Lanka will be buoyed by the return of their main strike bowler, as they head to Zimbabwe straight after the series to play World Cup qualifiers.
There are no such problems for Afghanistan, who have already qualified for the World Cup later this year in India.
Chameera was well backed up by part-time offspinner Dhananjaya de Silva, who finished with three wickets, including first-match hero Ibrahim Zardan.
Legspinner Wanindu Hasaranga polished up the tail claiming three for 42.
Zardan, who had top scored in the first ODI with 98 runs, was again among the runs with 54.
But the scoreboard pressure got to him as he edged an attempted cut shot that was well taken by Kusal Mendis behind the stumps.
Captain Hashmatullah Shahidi top scored with 57 runs, before being trapped leg before by de Silva.
After that, there was little resistance by the Afghan batters as they lost six wickets for 23 runs.
Sri Lanka came into the game making four changes, having lost the first ODI by six wickets on Friday.
Sri Lanka’s lower middle order was the driving force behind their total of 323, with the hosts scoring 109 runs in the last ten overs.
Fareed Ahmad and Mohammad Nabi were the pick of the bowlers for Afghanistan finishing with two wickets apiece.
The third and final ODI will take place on June 7 also at Hambantota.
