Carlos Sainz wants pit stop improvements

Carlos Sainz has said that Toro Rosso need to work on their pit stops.

Sainz missed out on a potential podium finish in Monaco earlier in the season and dropped from 12th to 19th after a problem during his first pit stop.

"We are just not good enough in that area," said Sainz. "We had improved it, we were maybe a bit better, a bit faster, but mistakes are still there, so it's not good enough."

"We managed to recover from 15th to 12th, ready to go hunting for the points, but when we did a first pit stop it was a disaster," he added. "We ended up behind all of the slower cars that we had overtaken in the first seven laps.

"From there you lose track position, you have to overtake all over again, you need to use your tires to overtake them and your race is backwards from then on."
