India, who have already qualified for the semi-finals, are looking for a fourth successive win in their last group two match.
Australia and Bangladesh are already out of contention, leaving Pakistan and the West Indies to battle for the second semi-final spot from the group on Tuesday.
India, whose previous three wins came while batting second, were given first strike by Australian captain George Bailey and found themselves in immediate trouble.
India's top order faltered after opener Rohit Sharma fell to part-timer Brad Hodge off the fourth ball of the innings and slipped to 66-4 by the 12th over.
Left-handed Yuvraj, who made one and 10 in the two innings he got to bat in the tournament, launched a spectacular counter-attack that included five boundaries and four sixes.
Skipper Mahendra Singh Dhoni made 24 during a fifth-wicket stand of 84 off 42 balls with Yuvraj before he was bowled by Mitchell Starc in the penultimate over.
Yuvraj himself fell in the final over, but not before he had struck timely form ahead of the knock-out round.
In the day's first match, Pakistan defeated hosts Bangladesh by 50 runs.
