Haas gives Giovinazzi Singapore practice run

Giovinazzi was due to make his third FP1 appearance of the season for Haas at Monza, but the plan was altered because the team feared bad weather would compromise its Friday running.

After driving Kevin Magnussen's VF-17 for the first time in Britain and a fortnight later in Hungary, Giovinazzi will take the Dane's seat again in the opening session in Singapore.

Giovinazzi has four other FP1 outings planned for the remainder of the season, in Malaysia, Mexico, Brazil and Abu Dhabi.

He will replace Romain Grosjean in Mexico and Magnussen elsewhere.

The Italian's F1 duties have yielded mixed results this season. Giovinazzi made a shock F1 race debut in Australia, standing in for Pascal Wehrlein at Sauber and almost making Q2 before impressing the team with 12th in the race.

He subbed for Wehrlein in China as well, but crashed out of qualifying and the grand prix.

Wehrlein returned for the following grands prix, but Ferrari agreed a deal with its engine customer Haas to field Giovinazzi in seven FP1 sessions over the remainder of 2017.

Giovinazzi was 0.4s slower than Grosjean and 16th in the first of those, in Britain, but then crashed out of a "brutal" FP1 for Haas in Hungary on his second appearance.

He has stated both his desire to be on the F1 grid full-time in 2018 and his confidence in Ferrari to sort his future - with his prospects boosted by a planned 'junior team'-style affiliation between the Italian manufacturer and the Sauber team.
