India closed in on a dominant victory over England on the penultimate day of the second Test at Edgbaston, as another Shubman Gill century helped them set a mammoth target.
England's bowlers were again frustrated by Gill, who added 161 runs to his first-innings score of 269 before India declared with a massive 607-run advantage.
Having been tasked with a world-record chase, England slumped to 72-3 by stumps and needing 536 more runs, leaving India on course to level the five-match series on Sunday.
With India resuming with a 244-run lead and nine wickets in hand, England needed early wickets, and after a couple of threatening deliveries, Brydon Carse had Karun Nair (26) caught for the breakthrough.
KL Rahul kept the scoreboard ticking over for India, reaching his half-century shortly before a misjudgement saw him cleaned up by Josh Tongue for 55, but Zak Crawley then dropped a simple catch from Rishabh Pant, who was on 10 runs with India at 141-3.
That moment proved costly for the hosts as Pant built a 110-run partnership with Gill, eventually seeing his chaotic knock of 65 off 58 halted by Ben Duckett's catch.
Gill, however, kept plugging away, combining for 175 runs with Ravindra Jadeja (69), with the former slamming 161 runs off 162 deliveries faced – including 13 fours and eight maximums – before he was caught and bowled by Shoaib Bashir.
Having been 96-2 when Gill arrived at the crease, India were 411-5 upon his departure, and they added 16 more runs before declaring, giving England a mammoth task.
England's hopes of completing their most improbable chase yet were dented after just 10 balls as Crawley's miserable day ended with a duck, Sai Sudharsan snaffling his loose drive.
Akash Deep (2-36) then took centre-stage, brilliantly bowling Duckett (25) and Joe Root (six) to leave England requiring the most astonishing of rescue acts, with Ollie Pope (24) and Harry Brook (15) resuming at the crease on day five.
Data Debrief: Gill and India make history
England have become noted for their comeback victories under Ben Stokes and Brendon McCullum, but this deficit looks to be a bridge too far.
Across two innings in the second Test, India have scored 1,014 runs – the first time they have reached 1,000 in any red-ball match.
It is the third time England have conceded 1,000 runs in the format, but the first since 1939 (1,011 v South Africa).
Gill, meanwhile, has racked up 430 runs in the second Test – the second-most by any batter in a Test match, after Graham Gooch's 456 versus India in 1990.
Gill has also become the first batter to manage separate scores of 200 and 150 in the same Test match.
