Petrovskiy qualified for the Russian squad in the men's team pursuit at the 2008 Summer Olympics in Beijing based on the nation's selection process from the UCI Track World Rankings. He delivered the Russian foursome of Alexei Markov, Alexander Serov, and Nikolay Trusov an eighth-place time of 4:06.518 in the prelims before his team was later relegated and overlapped to the Brits (led by Olympic time trial champion Bradley Wiggins) in the fourth match round.
