Real Sociedad B0-1Castellón

The 2026-27 La Liga 2 season begins at Campo José Luis Orbegozo, where Real Sociedad B host Castellón in the opening round. Both sides are coming off the same 16-day break since their last competitive matches, and neither has a league table record in the data for the new campaign.

The model gives Real Sociedad B a 40.3% win probability, compared to 33.1% for Castellón and 26.6% for a draw. The projected scoreline is 1-1, which highlights how evenly matched the two teams appear for this opener.

Real Sociedad B's recent home record is based on their last 20 matches at this venue: 6 wins, 7 draws and 7 defeats, a 30% win rate. They have averaged 1.3 goals scored and 1.3 conceded per home game.

Their last five results, listed most recent first, are L-D-L-D-W, meaning the most recent outing ended in defeat. Over that stretch they have averaged 1.2 goals scored and 1.6 conceded, a slightly worse defensive output than their longer home run suggests.

Castellón have played 20 away matches in the data, with 6 wins, 9 draws and 5 losses, also a 30% win rate. Away from home they have averaged 1.4 goals scored and 1.3 conceded per game.

Their last five results, most recent first, are D-L-D-W-W, with the most recent match a draw. That stretch includes two wins, and they have averaged 1.8 goals scored and 1.6 conceded per game over those five.

The two teams have met twice in the available record. Real Sociedad B won one and Castellón won the other. On 2026-03-07, Real Sociedad B beat Castellón 4-2 at home, and on 2025-11-15, Castellón won 5-4 at home. The combined score across those meetings is 15 goals, an average of 7.5 per game, and neither match produced two or fewer total goals.

With only two meetings, the head-to-head is too small a sample to carry much weight, but it does point to a high-scoring history between these sides.

Real Sociedad B's home record from their last 20 matches shows 6 wins, 7 draws and 7 defeats, a 30% win rate. Castellón's away record is 6 wins, 9 draws and 5 losses, also a 30% win rate but with more draws and fewer defeats. Both sides have averaged 1.3 goals conceded in these splits, while Castellón's scoring average away (1.4) is slightly better than Real Sociedad B's scoring average at home (1.3).

The numbers suggest home advantage is modest; the hosts' win rate is identical to the visitors' away win rate.

Both teams have had 16 days of rest since their last competitive match, with both playing on 2026-07-29, so there is no scheduling imbalance. This is the first league match of the season for each side, which adds uncertainty.

The head-to-head sample is just two games, and the model's confidence is medium. There is no league table data available for either team in this dataset, limiting positional context.

The Poisson model assigns Real Sociedad B a 40.3% chance of winning, Castellón 33.1%, and the draw 26.6%. The most likely exact scoreline is 1-1 at 12.6%, but because draws are spread across multiple scorelines, the aggregated home win is the most likely outcome at 40.3%. Expected goals are 1.35 for the hosts and 1.2 for the visitors.

The model projects about 2.55 total goals for the match. There is a 72.4% chance of at least two goals, 47% for three or more, and 25.4% for four or more. The probability of both teams scoring is 51.8%.

On winning margins, a draw is the largest single category at 26.6%. A home win by one goal is next at 21.7%, followed by an away win by one goal at 19.3%. Home wins by two or more are at 18.6% and away wins by two or more at 13.8%. The distribution indicates a tight match, with a single-goal margin or a draw more likely than a comfortable win for either side.

The data points to a closely contested season opener with a slight edge for Real Sociedad B on home soil. The model's medium confidence and the small head-to-head sample mean this is not a strong prediction. The most likely exact score is 1-1, even though the home result is the most likely outcome when all scorelines are combined.

If the model is wrong, the high-scoring nature of the two prior meetings may be a sign of greater variance than the expected-goals picture suggests. Either way, the margin is expected to be slim.
