Stevan Jovetic put Fiorentina in front with a low shot four minutes in and Cesare Natali doubled the lead with a header in the 63rd before Emanuele Calaio pulled one back for Siena with a penalty in the 88th.

Making his debut after transferring from Juventus, Brazilian-born Italy forward Amauri had several chances for Fiorentina but couldn’t find the target in his first action since the end of last season.

Fiorentina jumped from 14th to eighth, 19 points behind Serie A leader Juventus, which beat Udinese 2-1 Saturday.

Siena remained 17th and just four points clear of the relegation zone.
