England beat India by three wickets thanks to James Taylor and Jos Buttler's excellent stand, setting up a tri-series final with Australia.
Jos Buttler and James Taylor's superb sixth-wicket stand helped England recover from a top-order wobble to beat India by three wickets and book a spot in the tri-series final with Australia.
Having been restricted to 200 all out in Friday's one-day international at the WACA, India fought back to leave England reeling on 66-5.
Buttler (67) and Taylor (82) steadied the ship, though, and their partnership of 125 ensured Eoin Morgan's side made it home with a degree of comfort.
India, who bow out having lost all four of their fixtures, toiled against England's attack. Aside from Ajinkya Rahane's 73, the rest of the side failed with the bat, with Steven Finn - who recorded a five-for in England's win nine-wicket win over India in Brisbane - starring again by returning figures of 3-36.
India were put into bat and initially coped well as Rahane and Shikhar Dhawan (38) toughed it out to put on 83 for the first wicket - despite the former finding a few top-edges.
Dhawan became the first casualty when his attempted cut off Chris Woakes resulted in an edge through to wicketkeeper Buttler and that started an India collapse as five wickets fell for just 49 runs.
Moeen Ali (2-35) accounted for Virat Kohli (8) and Suresh Raina (1), before Stuart Broad (2-56) claimed his first scalp of the series when Ambati Rayudu (12) top-edged behind.
Finn then picked up the crucial wicket of Rahane, who smacked three fours and a six from 101 balls before also finding the safe hands of Buttler.
Finn quickly saw off Stuart Binny (7), before James Anderson (1-24) trapped captain MS Dhoni (12) lbw.
India were boosted slightly by Mohammed Shami's 25, but they needed a quick start with the ball.
Mohit Sharma (2-36) duly delivered when he had the in-form Ian Bell (10) lbw with one that kept low.
Moeen (17) soon followed, before medium-pacer Binny (3-33) accounted for Joe Root (3), Morgan (2) and Ravi Bopara (4) in quick succession.
England found their rhythm with Taylor and Buttler, though, the former showing poise and industry at the crease to slowly build his total, while the latter regularly found the boundary.
Taylor eventually departed when he picked out Binny at point off Mohit, and Buttler also fell when he lofted Shami to Rayudu at deep cover, but it proved a mere blip as England wrapped up the win with 19 balls to spare.
