Motorcycling: Vinales top in Argentina as Rossi, Lorenzo struggle

Spain's Maverick Vinales, who won the season-opener in Qatar, continued his blistering form on Friday by setting the fastest time in practice for Sunday's Grand Prix of Argentina as his rivals struggled.

The 22-year-old clocked a best time of 1min 39.377sec after two sessions on the hot and dusty Termas de Rio Hondo circuit with defending world champion Marc Marquez second fastest on a Honda, 0.301sec behind.

Unheralded Czech rider Karel Abraham, on a Ducati, was third fastest at 0.403sec off the lead.

Marquez, the 2013, 2014 and 2016 world champion, recovered well after managing a mediocre 11th best in the morning run.

However, it was a miserable two sessions for nine-time world champion Valentino Rossi, the teammate of Vinales, who was down in 16th in both sessions and ended the day 1.054sec behind his Spanish Yamaha partner.

Former champion Jorge Lorenzo, whose decision to join Ducati created the Yamaha vacancy for 22-year-old Vinales, fared even worse ending the day in 18th place, 1.122sec off the pace.

Rossi was third in the Qatar Grand Prix two weeks ago but Lorenzo, the 2010, 2012 and 2015 world champion, was a disappointing 11th in a race where his Ducati factory teammate Andrea Dovizioso was runner-up.
