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

Real Sociedad B vs Mallorca headlines Matchday 6 of the 2026/27 LaLiga2 (LaLiga Hypermotion) season on Saturday, 19 September 2026, with kick-off at Zubieta in San Sebastián. This is a meeting between two of the early surprise packages: Mallorca, relegated from La Liga last May and now under new manager Luis García, sit third with ten points from five games, while Ion Ansotegi's young Sanse side are ninth with eight points despite their ineligibility for promotion. The bookmakers price Mallorca as favourites in European odds at around 2.10 for the away win, with the draw near 3.20 and a home victory for Real Sociedad B at roughly 3.40.

Sanse arrive in solid form after a resilient start to the campaign. They claimed an impressive away win in 1-3 at Andorra on 12 September, battled to a hard-earned 2-2 draw away to Burgos, and although they fell narrowly in their opener, a 0-1 home defeat to Castellón, they have since shown real character. The 2026/27 squad, captained by Luken Beitia, blends Zubieta academy graduates with experienced campaigners, with Gorka Gorosabel already among the division's top scorers with two goals and Daniel Díaz Gandara pulling the strings in midfield.

Mallorca's squad for 2026/27 has adapted quickly to second-tier football under Luis García following Martín Demichelis' departure to RB Leipzig. Captain Antonio Raíllo anchors the defence, Arnau Tenas has been outstanding in goal with a goals-against average among the league's best, and Adrián Fuentes has netted three times already this season. Their recent results underline their strength: a convincing 2-0 home win over Sabadell, a gritty 0-0 stalemate at Eldense, and a composed 0-2 away triumph at Granada.

Tactically, this promises to be a fascinating clash of styles: Ansotegi's high-pressing, possession-based youngsters against García's streetwise, defensively organised promotion chasers. Real Sociedad B will look to exploit Zubieta's tight, atmospheric surroundings and the pace of Gorosabel in behind, but Mallorca's experience at both ends of the pitch — Raíllo's leadership and Fuentes' finishing — gives them the edge in the decisive moments. Taking into account current form, squad depth for the 2026/27 campaign and the European odds, our prediction for Real Sociedad B vs Mallorca is a 1-2 away victory for the island
