Toro Rosso rookie Carlos Sainz Jr. was left to rue a lack of running during practice for this weekend's Canadian Grand Prix due to mechanical issues and heavy rain.
Sainz Jr's first session was interrupted by a car problem while a torrential downpour at the Circuit Gilles Villeneuve washed out the final hour of running in the afternoon session.
"It’s been a difficult day for us," said the Spaniard, who has a quick spin at the first corner.
"This morning in FP1 we had some electronic issues, so we were slow and didn’t complete as many laps as we wanted to. It’s a bit annoying, because it’s very important for us to get as much mileage as possible here as this is a completely new track for me.
"In FP2 we didn’t have any issues, but it was a bit of a rushed session because we were expecting the rain to come. I felt that the car was improving lap after lap, but just as we managed to get to a decent level the rain arrived.
"The lack of running meant it wasn’t an ideal first day for a rookie especially on a difficult track like this one but hopefully we can use tomorrow’s FP3 to prepare ourselves better for qualifying."
