Kazuki Nakajima put in a 'good effort' to finish seventh at the Principality on Sunday and notch up points for the third time this season.
Despite challenging weather conditions, which made it the most dramatic race to date this year, Nakajima took a mature approach on the damp streets around Monte Carlo and was rewarded with two points.
Kazuki had a relatively trouble-free grand prix and would have finished higher but for a problem in his final pit-stop.
"It was really a difficult race, especially at the beginning when the track was very wet," reflected the
Williams man.
"I couldn't see anything in front of me, or at the rear, so I just tried to keep the car on track. I think we had some luck with the weather and the track conditions as I was on a one-stop strategy and it really worked well for me.
"It was a shame to have a problem in my pit-stop, but I still finished in the points so I am quite happy."
Williams technical director, Sam Michael meanwhile was impressed with Nakajima's form on his first outing in an
F1 car at Monaco.
"Kazuki drove well and didn't make any mistakes," he added. "He would have finished higher up the order, but we had a problem with a wheel nut on his final pit-stop and he lost places as a result. It was a good effort for his first time around Monaco in a
Formula One car."
Despite that success though, the Williams team were disappointed to see
Nico Rosberg come away empty handed in the sister FW30, especially as he had qualified so well.
Nico had a tough event and was fighting his was back up the field following two collisions in the opening stages, when he had a big off at the Swimming Pool complex with just 18 laps to go. The German escaped unharmed but was subsequently taken to hospital for 'routine checks'.
"It was good to get two points, but not a satisfactory race as we should have scored much more, but there are probably plenty of teams saying that today," added Sam Michael. "Nico made a couple of pit-stops for damaged front wings, and then had a crash on the entry to the swimming pool.
