Siena reached the Italian Cup semifinals for the first time by winning 1-0 at Chievo Verona on Wednesday despite having a player sent off.

Substitute striker Mattia Destro scored in the 54th minute but teammate Paolo Grossi was shown a red card six minutes later.

Chievo Verona defenders Nicolas Frey and Davide Mandelli had chances to take the game into extra time, but Siena also looked dangerous and Destro should have scored again in the 82nd minute.

Siena, which is four points above the relegation zone in 17th place in the Serie A standings, will play either Inter Milan or Napoli. Those teams play later Wednesday.

Chievo had the better chances in the first half and could have taken the lead in the 10th minute but Siena goalkeeper Simone Farelli did well to parry Fernando Uribe's fierce shot. Seconds later, Frey volleyed just over the bar.

The hosts went even closer when Kamil Vacek sent a tantalizing cross into the area in the 37th minute and Uribe's slide to reach the ball was inches away from making contact.

Siena's best chance of the half came in the moments before the break, Daniele Mannini receiving a cross from Grossi and firing narrowly wide of the far post.

Destro was brought on in the 52nd minute and the on-loan Genoa forward had an immediate impact. Alessandro Gazzi nodded on a corner to Destro, who was ideally positioned in the center of the six-yard box to head into the net.

Chievo's Davide Moscardelli almost leveled instantly but he headed narrowly wide.

The hosts received a boost when Grossi was somewhat harshly sent off for bringing down Francesco Acerbi on the halfway line.

However, Siena was solid despite the numerical disadvantage, and it was the visiting team which went closest to scoring when Destro failed to control a long ball with his head, allowing goalkeeper Christian Puggioni to rush out of his area and gather.
