Žalgiris won the King Mindaugas Cup for the second year in a row, defeating Lietuvos rytas 81–62 in the finals. Edgaras Ulanovas won the tournament MVP for the second straight year. In the 2017–18 EuroLeague, Žalgiris was again projected to be one of the last teams. During October–December, Žalgiris struggled with a 5–5 record, before winning a five-game streak to finish the first round 10–5, tied for third place in the standings. In the second round, Dee Bost was replaced by Beno Udrih. Žalgiris struggled for the first few weeks of the second round, but fought its way to an 18–12 record (sixth place) and qualified to the EuroLeague playoffs for the first time since 2001. The team qualified for the 2018 EuroLeague Final Four after beating Olympiacos in game 4 to clinch a 3–1 series win. The team achieved this despite having the second-lowest budget in the league. Žalgiris lost to Fenerbahçe in the semifinals, 76–67. In the third-place game, Žalgiris faced longtime rivals CSKA Moscow; Žalgiris lead by as much as 24 points, but CSKA rallied and Žalgiris narrowly won 79–77, achieving third place in the Euroleague. In the LKL, Žalgiris won the regular season, and beat Lietuvos rytas in the finals with a 4–1 record, earning their eighth consecutive LKL championship. This was the club's best season since 1999. After a near-perfect season, the off-season was difficult. Žalgiris lost its front court as Pangos went to FC Barcelona Lassa and Micič signed with Efes. Žalgiris signed Nate Wolters as the team's new point guard. After the departure of Beno Udrih, Žalgiris signed Donatas Sabeckis from Šiauliai, who lead the LKL in assists. Toupane left the team to sign with Olympiacos; to replace him, Žalgiris signed former-teammate Marius Grigonis, who was having a successful career abroad, to a multi-year deal, as well as talented guard/forward Thomas Walkup. At center, Davies had re-signed in April, and Kavaliauskas was re-signed in June. To replace reserve Martynas Sajus, Žalgiris signed Laurynas Birutis, who was loaned and had a successful season with Šiauliai. Several more reserves, Paulius Valinskas and Gytis Masiulis, were loaned to other LKL teams so that they could gain more playing time. Ulanovas also signed a new contract. Like the previous season, the biggest concern was the future of coach Jasikevičius. Despite offers from other EuroLeague teams and the Toronto Raptors, Jasikevičius remained with Žalgiris, signing a new contract.
