England's number two and three have come through the morning session unscathed on day three of the first Test match against India in the reply to the visitors' 457.
The hosts lost Alastair Cook at the start of the innings last night, but his fellow opener Robson and Ballance have steadied the ship, although they remain more than 300 runs behind India's first-innings total.
Ballance brought up his 50 with a cut behind point off the bowling of Stuart Binny in the 42nd over, with Robson following suit two overs later with a similar shot.
The England run-rate was even slower than India's, at 2.64, but Ballance (59*) and Robson (59*) safely saw them through the session for the afternoon's play, which will resume on 131-1.
