Sergio Perez concedes he didn't expect to finish on the podium when he started Sunday's Canadian GP 15th on the grid.
The Mexican driver, who claimed his first ever F1 podium at the Malaysian GP earlier this season, was in a for a treat on Sunday as he put his one-stop strategy to good use.
Starting on the soft tyres, the harder of the two compounds, Perez raced around the Circuit Gilles Villeneuve until lap 41 on that single set of tyres.
His late switch to the supersofts meant that Perez's rubber was much fresher than Fernando Alonso when it came to the final few laps and the Sauber driver overtook the Ferrari on the penultimate lap.
"When you start 15th on the grid, you don't expect to get a podium finish," Perez said.
"We went off very aggressively, and I managed to overtake a few cars with some difficult manoeuvres.
"The tyre degradation was not bad for me, and I managed to keep moving up the field.
"After such a bad day yesterday, when we had so much trouble with the brakes, this was a great boost for the team."
