Jack Leach and Dom Bess claimed three wickets each in a wild morning session on day four and then added one more apiece after lunch. Joe Root picked up the last two wickets on consecutive balls to finish the innings to ensure all 10 wickets fell to spin. 

Root ended Lasith Embuldeniya's rearguard cameo of 40 from 42 balls when had the Sri Lanka tail-ender caught by Jonny Bairstow and then bowled Asitha Fernando on the next ball. 

England resumed at 339-9 and added only five runs before being dismissed and handing Sri Lanka a 37-run first-innings lead. But far from enhancing the small advantage, Sri Lanka’s top order collapsed. 

The England spinners went wicketless in the first innings but made amends in the second, with the pitch offering plenty of turn and bounce. 

Spin was introduced early in the innings with Bess operating from the Dutch Fort End after just four overs of seam. 

Leach started from the City End and made his presence felt immediately by trapping Kusal Perera leg before wicket for 14. 

Bess then bowled into the rough and had Oshada Fernando (3) caught bat pad by Zak Crawley at forward short leg. 

Lahiru Thirimanne scored 13 before he flicked a Leach delivery into Crawley’s hands at short leg and the slide got worse, with three wickets falling for 10 runs within 13 deliveries. 

Angelo Mathews (5), who scored a century in the first innings, was bowled attempting a sweep to a ball from Bess which pitched outside off stump and turned sharply. 

Stand-in captain Dinesh Chandimal had a failure immediately after launching Leach for four to the mid-wicket boundary. He tried to clear mid-on from the next delivery, but didn’t get the elevation and was well caught by the 38-year-old Jimmy Anderson in the outfield. 

Niroshan Dickwella, who earned much admiration for his career best 92 in the first innings, was out for seven driving straight into the hands of Daniel Lawrence in the covers. 

Root's 186 helped England narrow in on Sri Lanka's first-innings total before was run out in the last over on day three. 

His 309-ball knock ended when he attempted to flick Dilruwan Perera to mid-wicket but the thick edge was grabbed by Oshada Fernando at short leg on the bounce. Root had taken a few steps out of the crease and, sensing an opportunity, Fernando threw the stumps down as a tired Root’s diving effort couldn’t save him. 

Sri Lankan left-arm spinner Embuldeniya finished with 7-137 from 42 overs.
