Kusal Mendis' unbeaten century helped Sri Lanka salvage a draw in the second Test with Zimbabwe as the tourists clinched a 1-0 series win.

Ten-wicket victors in the first Test, Sri Lanka found themselves in a difficult position on day five of the second match in Harare, Zimbabwe holding an overnight lead of 354.

They added six to their advantage before declaring on 247-7, but Mendis prospered on a dry pitch, finishing on 116 not out as he registered his seventh Test hundred.

Zimbabwe had hope when Dimuth Karunaratne (12) was caught behind off Carl Mumba, but Mendis and Oshada Fernando (47) mounted a recovery from 26-1.

Man of the Match Sikandar Raza trapped Fernando lbw to claim his eighth wicket of a match in which he also scored 106 runs.

Victor Nyauchi removed Angelo Mathews (13), named Man of the Series after top scoring with 277 across the two games, but the hosts could make no further inroads and the captains shook hands on a draw.
