Mumbai Indians steadied slightly after a shaky start, with Tilak Varma joining Naman Dhir at the crease.
Josh Hazlewood kept things tight, allowing just a leg bye and a single as MI tried to rebuild. Dhir managed to break free with a well-timed boundary, giving MI a brief lift amid the pressure.
The real drama, however, came from Bhuvneshwar Kumar, who was on a hat-trick and nearly made it happen. He came agonisingly close -- Tilak was beaten on one delivery, surviving by the narrowest of margins.
Despite the scare, Tilak and Dhir rotated strike and added a few useful runs, including a boundary from Dhir to ease the tension slightly.
After five overs, MI reached 41 for 3, still under pressure but showing faint signs of recovery after a brutal early spell from RCB's bowlers.
