Valtteri Bottas has finally put his back problems in the past.
The Finn even had to sit out the Melbourne season opener with a torn disc, but he returned in Malaysia and China with a new seat and driving position.
But despite being earlier hailed an absolute star of the new generation, 25-year-old Bottas has been outshone in 2015 by his Williams teammate Felipe Massa.
Bottas, however, finally got the upper hand in Bahrain qualifying.
And he declared afterwards: “My back is no longer a problem. I have no more pain.
“The change in the seating position has really paid off — I am not even worried that the problem could recur now.”
The biggest problem for Williams now is that the Grove team has clearly slipped behind Ferrari as the first force after Mercedes.
“At least there is no real threat from behind us,” said Bottas, referring to the gap between Williams and the big chasing pack including Red Bull, Toro Rosso, Sauber and Lotus. (GMM)
