The opening of the game started tense with very little offensive action during the first five minutes as both coaches tried to gain the advantage on defense (6-6).
Queralt Casas and Francesca Dotto exchanged free-throws (8-8). Then the flood gates opened with the lead changing on every score as they traded basket for basket until the end of the first quarter.
Chiara Zanin scored the last points of the first quarter for Italy to have the lead (17-15).
A trey by Beatrice Carta was the only score in open play that Italy were able to score during the first six minutes of the second quarter.
Spain managed to close down Italy aggressively while going on a 12-1 run to open the first lead of any significance (29-21) with just over four minutes to the break.
Carta was the driving force of the Italian team and ended the barren spell with a spin move in the paint. She also split a pair of free-throws.
Spain were suddenly on the back foot with Italy finishing the half with a 7-0 run concluded by Carta to square the game (31-31) at the interval.
Spain's dominance on the boards was negated by the high number of turnovers during the first half. So Miguel Martinez Mendez changed his players' tactical approach for the second half.
While Carta continued to cause Spain problems Laura Gil and Elena Diaz regained their offensive touch to keep the teams level (35-35).
Italy quickly made some adjustments and forced Spain into throwing the ball away.
Carta and Nene Diene took full advantage as Italy went 7 points clear (46-39). They held that advantage going into the final quarter (50-43).
Spain's troubles with Carta continued. But a trey by Elisabet Vivas and 2 points by Gil (48-52) forced Giovanni Lucchesi, the head coach from Italy, to call for a time-out with seven minutes left to play.
Marina Delgado scored for Spain to make it a 2-point game (50-52) with six minutes left to play.
Italy reacted almost immediately with 2 points from their center Lucia Morsiani and a trey from the top of the arc by Dotto.
Irene Cigliani was called for a foul on Delgado, who was awarded 3 free-throws. She calmly hit all three (53-57).
This was as close as Spain would get catching Italy because Morsiani and Dotto were on target again with back to back scores.
Italy controlled the last two minutes of the game and went on to win (66-61) for their first U18 FIBA Europe title since 1994.
Carta was the leading scorer with 17 points for Italy with Gaia Gorini the only other player in double digits with 10 points.
Despite Spain dominated in the battle of the boards, the 28 turnovers did not help them in staying undefeated in this year's U18 championship edition.
In vain Delgado and Diaz led the attack with 14 and 12 points each.
