2007-08: Kirill Petrov further built on this success, skating the entire season with Kazan’s senior team in the Super League and also continuing to hold a leading role on Russia’s U18 squad, earning the silver medal at his second U18 World Junior Championships. Petrov has shown mixed results in Russia, as he put up lackluster numbers last season with Ak Bars Kazan but excelled at the 2008 U-18 World Junior Championships. In Super League play, Petrov only registered 13 points in 55 games with Ak Bars Kazan during the 2007-08 season. However, he dominated at the WJC by recording seven points in six games. Petrov also came away with the “Best Forward” award and was named to the WJC All-Star Team.
2008-09: Kirill suited up with Ak Bars for only six games, scoring a goal with the KHL Club as they would win the KHL Championship. He would also play for Russia at the World Juniors, unable to register a point with the team en route to a Bronze Medal.
2009-10: In eight games with Ak Bars, Krill would be held off the scoresheet, again winning the KHL Championship. He would again dress for the Russian team at the World Juniors, scoring four goals and six assists in six games.
2010-11: Petrov saw increased ice time after going from defending Gagarin Cup champion Kazan Ak-Bars to Kharlamov Division rival Khanty-Mansiysk Yugra in the KHL. Petrov was scoreless in two games before going to Yugra. In 47 games with the third-place club he scored 8 goals with 11 assists and was +4 with 20 PMs. In six playoff games for Khanty-Mansiysk he scored 2 goals with 2 assists and was +2 with 8 PMs. His four points tied for second amongst Yugra scorers.
2011-12: Petrov returned to Kazan and scored a career-high 16 goals with 13 assists in 52 games for Ak Bars in his third full KHL season. He was minus-three with 8 penalty minutes as Ak Bars finished third in the Kharlamov Division. Petrov scored 3 goals with 2 assists and was minus-three with 8 penalty minutes in 12 playoff games as Kazan reached the East Conference semi-finals.
2012-13: Petrov skated for Ak Bars Kazan in his third KHL season and represented Russia in the European Trophy and 2013 IIHF World Championship tournaments.

Kazan finished first in the Kharlamov Division and reached the East Conference finals against Traktor Chelyabinsk. Petrov scored 4 goals with 1 assist and was +1 with 6 penalty minutes in 18 playoff games. He scored 1 goals with 2 assists in six Europe Trophy games and was +1 with 1 goal and for assists in eight games for Russia at the World Championship.

Kazan finished second in the Kharlamov Division and lost to Novosibirsk Sibir in a six-game first round playoff series. Petrov had an even plus/minus with 1 goal and 2 assists in six playoff games. He played for Russia’s national team in three Europe Trophy games and was minus-1 with no points nor penalties.
Petrov has size, speed and skill. He is hard to knock off the puck and can deliver an impressive physical presence, if properly motivated. In regards to his speed, Petrov is a very strong skater with impressive quickness. He is a capable puck handler and capable of making the most with very little room. Beyond his soft touch, Petrov also sees the ice well, but does need to further step up his game to make quick and reliable decisions. Even his errant passes tend to generate from some good ideas, but they are dangerous for his team and can at times cause costly turnovers. Another significant development area for Petrov is his defensive play. Overall, Petrov offers an impressive and tempting package of physical presence, skating ability and soft hands but needs to further improve his defensive play and his decision making.
Now in his eighth season of pro hockey in Russia, Petrov is back with Ak Bars Kazan for the 2014-15 season. Drafted in 2008 by the previous Islanders' regime when there was a dearth of talented forwards in the organization, Petrov tied his career high with 29 points for Ak Bars last season. At this point there doesn't seem to be a great need for his services with the Islanders.
