Unicaja vs.
Joventut Badalona ===
Unicaja's physical superiority and choral game demolished
Joventut's hopes in the quarterfinals, which held in during the first half, but was unable to respond to a 31–19 run in the third quarter at the
Gran Canaria Arena. The temporary absence of
Sam Dekker, which was the top scorer of the match with 23 points, was decisive. He missed the last six minutes of the third quarter after receiving an elbow from
Dylan Osetkowski in the fight for a rebound. The team from
Málaga, which was more aggressive in defense with 12 steals and more strength solid on the rebound, took advantage of this moment to seal the victory with the outstanding contribution of
Kendrick Perry (12 points),
Tyson Pérez (14 points), Osetkowski (18 points) and
Kameron Taylor (14 points). Unicaja performed 28 assists beating the record of assists in the tournament history. This was the second cup meeting between these two teams, with
Unicaja winning the previous meeting. ===
La Laguna Tenerife vs.
Barça ===
Marcelo Huertas, who at 41 years, 8 months and 16 days became the oldest player to play in a Copa del Rey match, led his team's comeback to eliminate
Barça and qualify for semifinal against
Unicaja at the
Gran Canaria Arena. The Brazilian performed 6 assists and 22 points, of which 12 points were scored in a final quarter of undisputed Canarian dominance (25–13), against a Catalan team that broke the record for scoring in a first quarter of the tournament (23–33), but faded after the break, weighed down by the injury of
Kevin Punter in the third quarter despite the contribution of
Tomáš Satoranský (17 points). It was the triumph of perseverance and faith for
La Laguna Tenerife, which never gave up despite fighting the entire match against them and, cheered on by the crowd, completed the comeback under the management of Huertas, who was well supported by
Fran Guerra (14 points). This was the fourth cup meeting between these two teams, with
Barça winning the previous three meetings. ===
Real Madrid vs.
Baxi Manresa === Real Madrid began with the aim to win back the Copa del Rey title with a clear win in the quarterfinals against
Baxi Manresa, which trailed on the scoreboard from the second half onwards and were unable to display their dynamic style of play at any time. The team coached by
Chus Mateo, winner of the tournament in seven of the last 13 editions and finalist in 10 of the 11 most recent seasons, took over the second quarter with a partial score of 23-8, supported by the intimidation of
Serge Ibaka and the points of
Mario Hezonja, which finished as the top scorer of the match with 24 points. The team coached by Diego Ocampo, with lack of success at the
three-pointer (4/26) and were unable to show its high pace of play, hinted at a slight improvement after the halftime, which was stopped by four consecutive
three-pointers from
Hezonja and
Sergio Llull (13 points), thus sealing a solvent win to
Los Blancos. This was the fifth cup meeting between these two teams, with
Real Madrid winning three out of the first four meetings. ===
Dreamland Gran Canaria vs.
Valencia Basket ===
Dreamland Gran Canaria qualified for the semifinals of the Copa del Rey, which it hosts, after overcoming
Valencia Basket in an intense quarterfinal duel in which the host team imposed its defense to the Valencian crew.
Mike Tobey stood out for the Canarian team with 19 points and 7 rebounds, deactivating the versatility of
Jean Montero, which performed 15 points and 5 assists, which was not enough to avoid the host team win. This was the sixth cup meeting between these two teams, with
Valencia Basket winning four out of the first five meetings. == Semifinals ==
