The Finn’s team mate ,Hamilton, took over the afternoon running completing 79 laps on a race simulation.
The Brit managing to get a full 20 laps in on the ultrasoft tyres.
However it was Williams who were once again the talk of the paddock with the Brazilian of Massa coming just one tenth behind the Finn on ultrasofts.
Williams rookie Lance Stroll was also back in the car and finally managed to complete a test session without crashing ending fifth with a 1:20.579 and 59 laps in total.
The Finn also got some good lap times setting a 1:20.406, good enough for third on the time sheets Before bringing the red flag out. In the last few minutes of the day he had a scary high speed spin at turn 3 ending the days running with a visit to the wall after a fairly small 53 laps.Red Bull also hit problems in the final stages. Max Verstappen getting up to fourth with the most laps before an engine failure out on track despite changing engines in the morning session as a precaution.
This however seems to becoming the story of this test. Mclaren yet again hitting problem Alonso only managing 46 laps and the twelfth fastest lap time almost 4 seconds off the benchmark set by Bottas in the Mercedes. The Spaniard spent over four hours in the pits despite having not needed another engine change.
Alonso has since gone on record as saying that he is unhappy with Honda and that it is their power unit that is preventing the woking based team from being up at the front and with patience already wearing thin between the two parties it looks like a bumpy road ahead.
Renault drivers Nico Hulkenberg and Jolyon Palmer had a good day with the latter suffering some technical problems in the afternoon with the least number of laps at 29 and the slowest time a 1:24.774.
Hulkenberg ended in seventh place.
Toro Rosso were another team that seemed stuck in the garage although Sainz did eventually get out and completed 92 laps.
The Force India of Perez had a productive day getting 100 laps in second only to The Red Bull of Verstappen in eighth place.
Haas and Sauber both had a decent day with Grosjean, the returned Wehrlein and Ericsson sandwiching Alonso in tenth, eleventh and thirteenth respectively.
Final standings for test 2, day 2 are as follows
