Sri Lankan pacer Matheesha Pathirana came up with his best IPL figures, grabbing four wickets as Chennai Super Kings defeated Mumbai Indians by 20 runs, despite a heroic unbeaten century by Rohit Sharma at the Wankhede Stadium on Sunday. Pathirana took the wickets of Ishan Kishan (23), Surya Kumar Yadav (0), Tilak Varma (31) and Romario Shepherd (1) to return figures of 4 for 28 as MI lost the steam in the chase of an imposing 206/4, managing to score 186 for six.
