Italian Grand Prix: Bottas beats Hamilton in second Monza practice
Valtteri Bottas edged out Mercedes Formula 1 team-mate Lewis Hamilton to the fastest time in second practice for the Italian Grand Prix.
Bottas clocked a 1m21.406s on the super-soft compound tyres, 0.056 seconds ahead of Hamilton, with Sebastian Vettel just a tenth further back in third.
The track was green early on as the morning rain had washed away the fresh rubber put down in opening practice.
Hamilton led the way after the opening third of the session with Mercedes focusing on running the soft tyres initially.
When attention turned to qualifying simulations, Vettel went fastest with a 1m21.546s, which was fractionally slower than Hamilton’s leading morning time.
Bottas then demoted Vettel and though Hamilton looked on course to usurp his team-mate, he lost time in the final sector and ended up second.
Kimi Raikkonen was fourth quickest, competing his quickest time on the second flying lap on the super-softs, as Ferrari provided more of a threat to Mercedes than it had earlier in the day.
Max Verstappen was the leading Red Bull in fifth, one second off the pace, with team-mate Daniel Ricciardo three tenths further back in sixth.
Both drivers face a tricky weekend as a raft of engine component changes means Ricciardo and Verstappen will receive grid penalties of 20 and 15-places respectively.
The McLarens of Stoffel Vandoorne and Fernando Alonso, who is set to start from the back after a 35-place grid penalty for engine component changes, showed an impressive turn of speed in seventh and eighth respectively, 1.5s off the pace.
Esteban Ocon and Felipe Massa, who aborted his first low-fuel run when he put two wheels on the gravel on the exit of the second chicane, completed the top 10.
Carlos Sainz Jr, who has a 10-place grid penalty after his Toro Rosso team changed the MGU-H, was 11th quickest.
His session ended early when his Renault engine let go and he stopped after the second chicane.
His team-mate Daniil Kvyat, who was 18th quickest and set his best time on the softs, ended his session early when he was called back into the pits as his team found a problem with the car.
The Renaults of Nico Hulkenberg, who spent much of the latter part of the session in the garage, and Jolyon Palmer were evenly matched in 12th and 13th, with just under half a tenth separating them.
Lance Stroll recovered from a spin at the Ascari chicane to end the session 15th quickest, four tenths adrift of Williams team-mate Massa.
Haas duo Romain Grosjean and Kevin Magnussen were just over two seconds off the pace in 16th and 17th.
In the closing minutes of the session, Magnussen stopped at the Ascari chicane reporting "broken suspension", leading to the deployment of the virtual safety car.

Italian GP FP1: Lewis Hamilton leads Mercedes 1-2 at Monza
Lewis Hamilton beat Mercedes Formula 1 team-mate Valtteri Bottas to the fastest time in first practice for the Italian Grand Prix at Monza.
Hamilton clocked a 1m21.537s on the super-soft Pirelli tyres to finish 0.435 seconds clear of Bottas, with Ferrari’s championship leader Sebastian Vettel 1.115s off the pace in third.
With the threat of rain looming, drivers headed out early in FP1 in order to maximise the dry but cool conditions.
Bottas led the way after the opening half an hour, the Finn clocking a 1m22.086s on the soft tyres.
Mercedes then switched to the super-softs, with Hamilton jumping to the top of the timesheets with a 1m21.868s.
The three-time world champion completed a flurry of laps on that compound, improving to a 1m21.729s and then a 1m21.537s before pitting.
Light rain eventually came with around 15 minutes of the session to go, with race control reporting the track was slippery in sector two, and everyone retreated back to the pits.
The Ferraris then headed out on super-softs, completing a practice starts at the end of the pitlane, before coasting around and returning to the pits.
The rain then eased, allowing another burst of laps in the final minutes of the session.
Kimi Raikkonen ended up fourth quickest, a fraction behind team-mate Vettel, with Red Bull’s Daniel Ricciardo and Max Verstappen a tenth further back in fifth and sixth respectively.
Ricciardo and Verstappen are set for a tough weekend after Red Bull chose to change Renault engine components ahead of the session, meaning they will take 20 and 15-place grid penalties respectively.
Sergio Perez pipped Force India team-mate Esteban Ocon to seventh while Stoffel Vandoorne was the highest placed McLaren in ninth with team-mate Fernando Alonso 15th.
Honda fitted an upgraded power unit, known as ‘spec 3.7’, to Alonso’s car for first practice, sparking a 35-place grid penalty for Sunday’s race.
The Spaniard then ended the session early so Honda could switch back to an older spec unit – the one Alonso raced at Spa – for the remainder of the weekend.
Honda wanted to use the session to test performance, but save mileage on the engine for Singapore, as it feels a good result is possible at the next race.
Felipe Massa completed the top 10, two seconds off the pace, but nearly half a second quicker than Williams team-mate Lance Stroll.
With rain expected, Haas changed plans and stood down Ferrari junior Antonio Giovinazzi to allow Kevin Magnussen to get running in dry conditions.
It is expected Giovinazzi will get an opportunity to drive in FP1 in Singapore instead.
