What we missed
Five markets landed, but a goalless second half killed our biggest call. Here is what the data said and what the game did instead.

Five from nine. The scoreline read 1-1, both teams scored, the half-time result landed, the goals range landed. Then the second half happened, and our highest-confidence call went cold.
We locked the second-half goal at high confidence. We meant it. The rotation logic was sound, the substitutions-open-up-space argument was real, and the attacking numbers on both sides backed the call hard.

Second half goal is the easiest call in this match. Both managers will ring the changes at half time, fresh legs open space.
Tom
The calibration data backs you up. Second half goal at high conviction hit 90% in graded rounds. With both attacks this productive, it's almost a certainty.
And then nothing. S. van Persie put Feyenoord ahead in the 17th minute, Rayo's A. Garcia levelled it before the break, and the second half produced precisely zero goals. Two yellows, some possession, and a flat friendly finish. Football did what football does in pre-season: the legs went, the urgency disappeared, and the managers got what they came for at half-time and stopped pushing.
We did not see that coming. We should have weighted the friendly-context caveat harder on the second-half market specifically. The case for goals after the break relies on fatigue and space opening up, but in a pre-season game at a neutral venue in the USA with both squads already rotated heavily, the second half can just as easily become a training exercise. That is on us.
The clean half call was the other loss on paper. We called home clean sheet, and the actual result was both sides scoring in the first half. That one stings less because our reasoning was conditional: Rayo needed to score in both halves for the market to lose, and they did exactly that through Garcia in the 41st minute. We flagged the risk.

Rayo need to score in both halves for this to lose. That's not impossible with Palazón, but the first half especially could be quiet.
It was not quiet. Rayo were competitive from the start, and their foul count and physical approach showed up in the two yellow cards they picked up across the 27th and 46th minutes. Feyenoord added one of their own in the 57th. The scrappy, physical encounter we described in our preview read was accurate. The scoreline was accurate in structure if not in result: both teams scored, neither side ran away with it, and the 1-1 fell comfortably inside our 1-4 goals range.
Home to score, away to score, half-time home or draw, goal in the first half, total goals over 1.5. Five calls, five hits. The exact score went 1-1 against our 2-1 prediction, which is close enough to feel cruel but wrong is wrong.
The second-half goal market in pre-season friendlies deserves a specific penalty on conviction, separate from the general friendly caveat we already apply. When both sides have completed their main tactical work by half-time and the squad has been rotated across 45 minutes, the second half can deflate fast regardless of what the attacking numbers say.
Rayo's first-half goal from Garcia also confirms what we said about Palazón's presence making a Feyenoord clean sheet unrealistic over 90 minutes. That read was right. The direction of the second half just did not cooperate.
Feyenoord head into pre-season with questions about their injury list still unanswered. Ten players unavailable is a number that will matter more once competitive football starts. We will be watching.
