MODENA, May 9 (Serie A) - Modena face a nerve-jangling end to the season after defeat by a Siena side who can now plan for another season of Serie A football.
Last year saw Siena promoted to the top-flight for the first time in their 100-year history, and they have now provided the perfect finish to their centenary festivities with this win.
Modena, on the other hand, can only hope they can book a place in a relegation play-off with a Serie B club, but they face competition from Empoli and Perugia.
Two of those three clubs will go down automatically next week, while the third will have the play-off to prepare for.
Modena face a tough match against a Lazio team who are battling for a Champions League place, while Empoli host an Inter Milan outfit who still need three points for the same reason.
Perugia will face an already-relegated Ancona and may feel that they have the edge.
Modena, who have had two seasons in the top-flight, were the first to threaten to score after half an hour.
Maurizio Domizzi tried his luck with a well-struck free-kick and was only denied a goal by a slight deflection off the Siena defensive wall.
Siena made the most of that let-off by taking the lead three minutes before the break when Rodrigo Taddei headed home following a corner on the right.
That is the way the score stayed until nine minutes from time when Taddei netted his and Siena's second.
The Brazilian left Adriano Zancope in the home goal with no chance to save after meeting Gianni Guigou's cross with a powerful strike.
Modena pulled a goal back three minutes later through Massimo Marazzina, but their hopes of salvaging something from the game had taken a bad blow midway through the second half when they had Mauro Mayer sent off.
They also missed a series of opportunities.
Marco Fortin made a brilliant save to deny Diomansy Kamara with the first chance in the 65th minute, but the Siena goalkeeper should have been picking the ball out of the back of his net just moments later.
With Fortin on the ground and reasonably helpless, Ayodele Makinwa was faced with a virtual open goal but he failed to hit the target and the 10 men of Modena missed out on a great chance to draw the game level at 1-1.
The hosts battled manfully to the end of the game, however, and reduced the score to 2-1 seven minutes from time when Marazzina beat Michele Mignani before lashing a left-footed shot beyond Fortin.
Modena pushed forward in search of a last-gasp equaliser but were caught short in injury-time following a Siena counter-attack which led to the visitors' third goal.
Alessandro Cucciari was the instigator with an intelligent pass to Enrico Chieso who made no mistake in front of goal.
