Aprilia's Vinales claims sprint win at GP of the Americas

Aprilia's Maverick Vinales won the sprint at the Grand Prix of the Americas on Saturday to claim his second straight sprint victory of the season ahead of Marc Marquez and MotoGP championship leader Jorge Martin in an all-Spanish podium.

The victory was redemption for pole-sitter Vinales, who also won the sprint at the Portuguese Grand Prix in the previous round but crashed on the final lap of the race in Portimao due to a technical problem when he was running in second place.

"Can I just say I'm dreaming! I want to keep going. The level was amazing... We deserve it," said a grinning Vinales, who became only the second rider to win back-to-back sprints in MotoGP.

Vinales had the perfect start as he shot off the line to take the lead while Gresini Ducati's Marquez moved up from third to second when he overtook GasGas Tech3 rookie Pedro Acosta as soon as the lights went out.

The front-row trio peeled away from the rest of the pack but behind them Pramac Racing's Martin, who crashed twice in qualifying, moved up to fourth in an attempt to reel them in.

As Vinales continued to increase his lead, Martin managed to elbow Acosta out of the way with five laps to go and set his sights on Marquez.

Marquez, who has won at the Circuit of the Americas seven times, did make a mistake when he nearly went wide but he managed to keep hold of second place for another sprint podium after Vinales took the chequered flag.

Martin ran out of laps to launch an attack but third place extended his championship lead to 24 points.

"We had two crashes (in qualifying) but I was able to make that second row," Martin said.

"It was a tough race, I suffered some issues but we finished on the podium - that's the most important thing."

Acosta finished fourth
