Root's was shaping as a match-defining innings when he was cramped for room by a short delivery from the impressive Shannon Gabriel and couldn't keep the ball down towards gully. It still needed two grabs from Shai Hope to complete the catch but, unlike his brother yesterday evening when Root had 10, it didn't go to ground.
The same can't be said of the chance offered by Malan on 32 a few moments later when he edged a drive at Jason Holder and Kieran Powell at first slip, distracted by Shane Dowrich diving across then bailing out, put it down. It was Powell who dropped Root early in his first innings.
England resumed on 171 for 3 and made steady progress for much of the first hour. Root went to his second fifty of the match with two boundaries in the opening over, both through the gap between second slip and gully although neither were chances. He was fluent off his pads whenever the bowlers strayed, but was again challenged by Gabriel before he struck in what became the final over of his spell.
Malan was forced to dig very deep, adding just 20 off 83 balls during the session. His first scoring shot of the day was a pleasant straight drive, but precious little else came to him easily. He narrowly evaded square leg with a flick off his hip and then the life came his way in Holder's opening over with a very loose drive outside off.
Holder made the old ball move and there was an appearance of the lesser-spotted Devendra Bishoo in the second hour of the morning. There was some turn for the legspinner but his length was inconsistent - perhaps that was the concern Holder had, but it was hardly a fair chance for Bishoo to wait so long for an extended bowl - and Stokes put him through the leg side three times.
