- Spain's Marc Marquez becomes youngest winner of a premier level motorcyling race
- The 20-year-old triumphs in just his second MotoGP event since moving up from Moto2
- His teammate Dani Pedrosa finishes second at inaugural Grand Prix of the Americas
- Marquez is tied with world champion Jorge Lorenzo ahead of their home grand prix
Marc Marquez announced himself as motorcycling's bright new hope when he became the youngest rider to win a top-level race in Sunday's inaugural Grand Prix of the Americas in Texas.
The 20-year-old had been the youngest pole sitter when he topped Saturday's qualifying, and he followed that up by heading off Honda Repsol teammate Dani Pedrosa in the second event of the new MotoGP season.
World champion Jorge Lorenzo, who won the opening race in Qatar, came home third for Yamaha to be tied on points with his young compatriot at the top of the standings ahead of their home Spanish Grand Prix next month.
"To be third in my first race in Qatar was a dream and now, to take the victory in the second race -- that's even better!" said Marquez, who won the Moto2 championship last year.
"The race was quite hard, especially in terms of physical condition towards the end. I had some problems with the front that I hadn't had in practice, but even with that I was able to push and keep up a constant rhythm -- not so fast, but enough.
"So I'm very happy with that and I want to say thanks to all of my team. Without them this would not have been possible."
Britain's Cal Crutchlow was fourth on a Monster Tech 3 Yamaha ahead of Germany's Stefan Bradl and Italy's seven-time world champion Valentino Rossi -- back at Yamaha after two disappointing years with Ducati.
Rossi's replacement at Ducati, Andrea Dovizioso, was seventh ahead of Spain's Alvaro Bautista, veteran American Nicky Hayden and another Italian, Andrea Iannone.
