Real Sociedad B vs Mallorca Prediction & Betting Tips (19 September)

Real Sociedad B host RCD Mallorca at Instalaciones de Zubieta on Sunday, 20 September 2026, in a LaLiga2 Round 6 clash that pits two sides with very different ambitions this season. The hosts, coached by Ion Ansotegi and captained by Luken Beitia, are a young reserve side looking to consolidate in the Segunda División, while Mallorca — relegated from La Liga and now under new boss Luis García, who replaced Martín Demichelis this summer — have started the 2026/27 campaign strongly and sit near the top of the table, making this trip to San Sebastián a real test of their promotion credentials.

Real Sociedad B come into this fixture with mixed early-season form: after opening the campaign with a narrow home defeat to Castellón, they bounced back with a 2-0 win at Albacete, a hard-fought 2-2 draw away at Burgos, a stalemate against Tenerife, and most recently an impressive 1-3 victory away to Andorra. That win in Andorra showed the attacking potential of this youthful squad, with Gorka Gorosabel — the team's top scorer so far — pulling the strings, while Aitor Fraga has been reliable between the posts. However, a long injury list including Iker Calderón and Iñaki Ruperez, together with the fact that the reserves struggle to keep clean sheets at Zubieta, remains a concern ahead of a visit from one of the division's strongest attacks.

Mallorca, meanwhile, have been one of the stories of the young season, going unbeaten in five league matches despite an opening defeat at Granada. Luis García has blended experience and new faces well: captain Antonio Raíllo and Martin Valjent anchor the defence, Arnau Tenas has arrived on loan to take the gloves, while Zito Luvumbo, Adam Buksa and Pablo Torre add quality in attack. After a goalless 0-0 draw at Eldense, the Balearic side returned to winning ways in style with a 2-0 home win over Sabadell, in which Adrián Fuentes scored both goals. The only downside for García is the continued absence of Abdón Prats and Jan Salas through injury, though the depth of the 2026/27 squad means Mallorca travel north with confidence and genuine momentum.

In terms of betting value, the European odds for this LaLiga2 encounter reflect Mallorca's superior start: an away win is priced around 2.05, the draw is available at roughly 3.45, while a home victory for Real Sociedad B pays approximately 3.40 — numbers that underline how highly the market rates the visitors' unbeaten run and defensive organisation. With Mallorca's experienced spine contrasting against Sociedad B's promising but raw youngsters, we expect an open contest at Zubieta where the visitors' extra quality tells in the second half. Our prediction: Real Sociedad B 1-2 Mallorca, with Fuentes or Buksa leading the line for the away side and Gorosabel the likeliest source of a consolation for the ho
