Opener Keaton Jennings hit a debut century as England reached 288-5 on a fluctuating first day of the fourth Test against India in Mumbai.
The Durham left-hander, called up last week, was dropped before scoring but put on 99 with captain Alastair Cook (46) and went on to make 112.
Jennings, Moeen Ali, who made 50, Joe Root and Jonny Bairstow all fell to Ravichandran Ashwin.
India lead 2-0 in the five-match series.
South Africa-born Jennings, 24, supported first by Cook and then by an increasingly confident Moeen, put England in a strong position, although they were helped by defensive fields from India.
