Colombo: Sikandar Raza hit a gritty 97 not out to help Zimbabwe recover from a top-order collapse and stretch their second innings lead over Sri Lanka to 262 in the one-off Test on Sunday.
The visitors were 252 for six at stumps on day three, with Raza and Malcolm Waller (57) putting on an unbeaten 107-run stand for the seventh-wicket at Colombo's R Premadasa Stadium.
Raza lifted Zimbabwe from a precarious 23-4, followed by 59-5, after Sri Lankan left-arm spinner Rangana Herath rattled the visitors' batting with four early wickets.
Herath, who got three wickets before the lunch break, bowled Sean Williams for 22 in the second session as Zimbabwe teetered dangerously close to losing their 10-run advantage.
It was then that Raza put together 86 runs with Peter Moor (40) for the sixth wicket to turn the tables on Sri Lanka. Moor fell to paceman Lahiru Kumara.
Raza, who registered his fifth Test fifty, used the sweep shot to great effect against the spinners as he found another partner in Waller to thwart the Sri Lankan bowling attack.
Earlier skipper Graeme Cremer helped Zimbabwe take the lead after claiming his maiden five-wicket haul in a Test, helping bowl Sri Lanka for 346 in the morning session.
But it was Herath's left-arm spin that undid the fine work from leg-spinner Cremer (5-125).
Herath, who registered his 30th Test five-wicket haul in the first innings, ran riot at the start of Zimabwe's second essay to get the wickets of Hamilton Masakadza, Tarisai Musakanda and Regis Chakabva.
Off-spinner Dilruwan Perera joined forces to get the prized wicket of first-innings centurion Craig Ervine for five at the stroke of lunch.
While Sri Lanka look for redemption under new Test captain Dinesh Chandimal after their shock loss in the one-day series against Zimbabwe, the visitors eye their first-ever Test win over the islanders.
Zimbabwe - 356 (Ervine 160, Herath 5-116) and 252 for 6 (Raza 97*, Waller 57*, Herath 4-85)
Sri Lanka - 346 (Tharanga 71, Chandimal 55, Gunaratne 45, Cremer 5-125)
Status - Zimbabwe lead by 262 runs
