Career
Astana Tigers
Ponomarev was brought to the capital Astana by newly formed Astana Tigers in 2000, along with other Kostanay players such as Rustam Yargaliev. They lived in the Olympic reserve school with other athletes. Ponomarev started playing in the Kazakhstan Basketball Championship during the 2002-2003 season.
At only 15, he already measured 209 cm (6 ft 10 1⁄2 in), the second tallest player in the country.
He entered the 2009 National Basketball Association draft as an early entrant in May 2009, but withdrew before the deadline. After participating in the Reebok Eurocamp in Treviso he signed a 4-year contract with French side Hyères-Toulon Var Basket in June of the same year.
However it later emerged that he was still under contract with Astana, who opposed the move, leading him to stay in Kazakhstan. In September 2010 the Kazakhstani moved to Serbian side FMP Belgrade following the expiry of his Tigers contract, reportedly signing a multi-year deal.
He averaged only 5.7 minutes (08 points and 14 rebounds) in 9 games for FMP, leading to a mutual separation with the Serbians.
He then joined second division Russian Basketball Super League side Spartak Primorje in early 2011, first on trial then on a permanent contract in February. Ponomarev stayed there until the end of the season, contributing 6.1 points and 5.1 rebounds in about 14 minutes per game in 14 games. Whilst in Russia, he was contacted by Valeri Tikhonenko, the general manager of newly formed British Columbia Astana to ask him to join the club and play in the VTB United League, an offer he accepted.
He was named the initial Top Kazakh Player by the league in 2013 after posting 8 points and 5.3 rebounds for a 10.4 efficiency rating in the league during 2012-2013.
Ponomarev made his debut for the Kazakhstan national basketball team with the Under-18"s at the 2004 International Basketball Federation Asia Under-18 Championship. He played for the senior side at the 2007 International Basketball Federation Asia Championship, leading the team in scoring and rebounding with 17.6 points and 7.1 rebounds per game, 8th best in the tournament for the latter.
In the 2009 International Basketball Federation Asia Championship he posted 15.6 points and 9.6 rebounds (3rd best in tournament). In the 2013 International Basketball Federation Asia Championship he had a lessened impact, posting 7.8 points and 7.8 rebounds, albeit again best rebounder for Kazakhstan (and 8th best overall).
His coach Matteo Boniciolli, whilst labeling him a major player for the team, bemoaned his up and down performances.
At the 2014 Asian Games he contributed 11.4 points and a tournament best 9.3 rebounds for Kazakhstan. Ponomarev originally practiced kickboxing, with no interest in basketball until he was 10 years old and attended a training session with a friend, at first he only played as a hobby before taking the game more seriously later.
