India slumped to its first ODI bilateral series defeat at home since 2009-10 on Thursday.
Pakistan beat the host by 85 runs in the second one-dayer to take an unassailable 2-0 lead in the three-match series.
Riding on Nasir Jamshed's second consecutive century, the visitors posted 250 all out and then shot out the Indians for a paltry 165 to record a convincing victory with two overs to spare at the Eden Gardens.
