Siena relied on their superior finishing to beat Cagliari Calcio 3-0 in an open game between two relegation rivals.
Gianluca Pegolo was the busier of the two goalkeepers in the opening stages, as he made full stretch saves to deny palm Cagliari pair Thiago Ribeiro and Lorenzo Ariaudo.
Erjon Bogdani made a rare starting appearance for the hosts and his selection was justified four minutes before half time.
The Albanian was in the right place to tap home a rebound after Michael Agazzi had parried Luigi Giorgi's fizzing effort.
After 81 minutes of furious end-to-end football, Siena doubled their lead. Emanuele Calaio latched onto a Roberto Vitiello cross-field pass and thumped a fantastic half-volley into the far top corner of the net.
It was 3-0 two minutes later, as Cristian Del Grosso beat the offside trap down and angled a low drive past Agazzi.
Cagliari are now without a win in their last six away games.
