It came after a poor showing in qualifying where a hydraulics failure prevented him running in Q2 to see him start 15th.
Had the race run without the tyre changes late on, it could have been somewhat of a dull race with the field reasonably well spread out. But Russell thinks a small change could make that happen less often.
“Definitely a combination," Russell said to Sky Sports. "For me, it was definitely slicks. I said the lap before, if this was qualifying, I’d be pitting now.
"The thing you don’t know as a driver is with 13 laps to go, are you going to be able to regain those positions? I was happy to make that decision and it’s always challenging when you’re in the slipstream of cars, there’s still a lot of spray.
"Even when the track has semi-dried. You’re trying to judge [whether] it’s dry or the spray coming from proper wetness on the track or just dampness.
“I think after a bad qualifying, these are the conditions you pray for. If I was top five on the grid, you probably wouldn’t be feeling the same way. I think the sprint race is an interesting one.
"I still feel like it’s too short. In normal circumstances, just dry conditions, it would’ve been a pretty boring race. Something like mandating the soft tyre for the sprint race and a bit more tyre deg, you’ve got to think about it a bit more, a bit more action.
"At the moment, you put the medium (on) and you’re just flat out the whole race, in a DRS train and there would’ve been nothing you could do.
“The most challenging part was coming out of the pitlane because we’re driving on the track and drying the track. No one is driving in the pitlane. So, the pitlane was the wettest point.”
