Red Bull hit more trouble in Bahrain

Red Bull's hopes of getting their 2014 preparations back on track with a trouble-free final test evaporated on the first day's running in Bahrain. Daniel Ricciardo managed his team's fastest time at Bahrain this winter early on, but was consigned to the garage for most of the rest of the day. Ricciardo went back out late on but finished seventh, 2.6 seconds adrift of Force India's pace-setter Sergio Perez. Williams's Valtteri Bottas was second fastest, then Ferrari' Kimi Raikkonen. Nico Rosberg of pre-season favourites Mercedes was fourth quickest, after the team ended their running a little under an hour early following a problem the team declined to identify.
