Champion Marc Márquez won the Valencia MotoGP on Sunday to conclude his dominant season with a 12th victory of the year.

Three-time former MotoGP champion Jorge Lorenzo finished his last professional race in 13th place.

The 32-year-old Lorenzo, a Honda teammate of Márquez, retires with 47 grand prix victories since debuting in the top class in 2008. He missed three races this season after breaking a vertebra in practice in July and hasn’t finished better than 14th since then.

“I didn’t feel good in the race so I decided to keep a constant pace so I could avoid a crash and be able to enjoy my final race,” Lorenzo said. “Many thanks to Honda for their support during a year that has been very difficult.”

Márquez secured his sixth MotoGP title last month.

French rookie Fabio Quartararo finished the race second after starting from pole position. Jack Miller was third.

Several riders crashed out.

Johann Zarco was hit in the lower legs by a fellow competitor’s motorbike.

Zarco had fallen off his bike and was jogging away from the track when Iker Lecuna also crashed. Lecuna’s bike slid into the back of Zarco’s legs and flipped him over, slamming him into the gravel.

Zarco was taken to the medical center for tests.
