Siddhesh Lad struck a gritty 116 while Shams Mulani made an unbeaten 79 to drive Mumbai to 336-5 after an early wobble on the opening day of their Ranji Trophy Elite Group D match against Jammu and Kashmir here on Wednesday.

Mumbai were in a spot of bother at 141-4. But Lad, who compiled his knock off 156 balls (17x4, 3x6), and Mulani (79 not out off 125 balls, 8x4, 1x6) bailed their side out with a strong 159-run stand.
