It was a strange day in Malaysia. Part of the strangeness was down to the weather. The familiar pattern of disrupted sessions as the rain fell, but not hard enough to allow the MotoGP riders, in particular, to spend much time on the track in the afternoon.

There was a twist, however, a particularly Malaysian one at Sepang: the heavy shower which passed over the track at the start of the afternoon session for MotoGP left part of the circuit soaking, with water a couple of centimeters deep at turns 1 and 2, while the rest of the circuit quickly dried out almost completely. It at least added a little novelty to the disruption, along with the frustration of another wasted practice.

The real strangeness came at the start of the day, however. It took about 10 minutes for observers to notice that Maverick Viñales had not gone out on track and there was suspiciously little activity in the Avintia Blusens garage. Once they noticed, low-level pandemonium broke out: within seconds, a throng of Spanish journalists crowded out of the media center and hastened on their way into the paddock, to find anyone and everyone and learn what they could.

As they drifted back in, and as TV pictures started to appear showing an empty Blusens garage, Viñales walking through the paddock accompanied by his father and the Dorna media officer, and team managers Raul Romero and Ricard Jové gathered in discussions, it was clear that there was something very wrong.

When it was revealed what that was – that Viñales had decided to quit the team with immediate effect – it sent a shockwave through the paddock. Riders quitting teams with races left in the championship is unusual; to do it while that rider is second in the title chase and still in with a shot at the championship is unheard of in motorsport.
