The 2009–2010 Baltic League (known as the Triobet Baltic League for sponsorship reasons) is a 16-team football tournament held in the Baltic states. Five top teams from each participating country – Estonia, Latvia, and Lithuania – along with the winner of the 2008 season will play a 4 round and 2 legged (excluding final) play-off style knockout tournament. It is held from Autumn 2009 through Summer 2010.
Although TVMK initially finished 3rd, they were demoted to 10th place at the end of the season due to severe financial difficulties. The team was later disbanded.
Daugava Daugavpils (5th) merged with Dinaburg FC, with Dinaburg retaining its name. After FK Rīga (6th) went bankrupt Jūrmala were given the freed spot as the next best placed team.
FBK Kaunas (2nd) and FK Atlantas (6th) withdrew from the top league, citing serious differences with the Lithuanian Football Federation. FK Žalgiris (5th) were denied A Lyga license and were demoted to I Lyga. FK Šilutė (8th) were relegated to I Lyga because of their league position. Eventually two I Lyga sides, Tauras and Banga, were awarded the two remaining spots, as they were both promoted to the A Lyga.
