Dinamo Sassari battled from 22 points down in the fourth quarter to lose 73-62 at AS Monaco and give themselves a fighting chance of reaching the Basketball Champions League semi-finals.
Monaco started strongest at Stade Louis II and were nine points up at the midway point, before stretching their lead to 60-40 by the end of the third period.
But the hosts' form deserted them somewhat in the fourth, as Dinamo rallied to reduce the deficit to 11 and tee up a fascinating second leg in Italy next week.
The margin is the biggest of all four quarter-finals, but it should have been even better for Monaco, who were lucky not to see their advantage reduced further in the closing seconds, when Rok Stipcevic's lay-up rimmed out.
Stipcevic scored a game-high 17 points - a record shared with Monaco's Billy Ouattara
In the day's other match, Pinar Karsiyaka triumphed 74-71 over Umana Reyer Venezia and it was a similar story, with the Italians storming back from a 15-point deficit to stay in contention.
Reyer - for whom MarQuez Haynes top-scored with 19 points - are unbeaten at home in the competition and will be full of confidence ahead of next week's return leg.
They would have to go some to be as pumped as Karsiyaka were for Wednesday's match, though.
