Sri Lanka turned the screws on Pakistan in the first Test in Galle after battering the tourists with both bat and ball on the third day on Sunday.

Sri Lanka bowled Pakistan out for 100 in the first innings in reply to their own 472, with off-spinner Suraj Randiv grabbing 4-13 and left-arm spinner Rangana Herath taking 3-30.

The hosts surprisingly declined to enforce a follow-on despite a substantial lead of 372 runs and made 137-5 in their second knock when skipper Mahela Jayawardene declared in the final hour.

Pakistan, set an improbable victory target of 510 runs, were reduced to 36-3 by stumps after seamer Nuwan Kulasekara dismissed stand-in captain Mohammad Hafeez and Taufeeq Umar.

The hosts, overwhelming favourites to go 1-0 up in the three-match series, have two days to force a result on the spin-friendly wicket despite forecasts of wet weather on both days.
