I agree with Ferrari this time,they did the best choice for Sainz,sure he would have been second as he would have passed also Hamilton with the pace he had but I am sure he would have had a puncture if he kept racing at that pace or if he would not get the pace the tire would degrade surely in the last 10 laps and everybody else would have surpassed him again.So Ferrari did for once the right call with Sainz,they even got the fastest lap of the race.
Leclerc made the mistake exactly where he needed the most not to do it,now Verstappen 62 points ahead and when Leclerc loses Verstappen extend the gap with minimum of 15-25 points,when Verstappen loses Leclerc closes the distance by just 6-12 points and this says a lot for the title fight.I agree that in 10 races is almost impossible to close the gap by 62 points unless bad things happen to Verstappen.
Ferrari may have the most performant car right now but Max is more solid at the moment.
Keep also in mind Max is already in his 8th year in F1, even if he is so young he is still experienced, the rookie Max was the more exciting driver but too reckless.
Another advantage in the second part of the season, Ferrari already got a penalty so they have some free parts for the cars, while if Redbull will need more they will take a penalty.
