World Superbike Championship leaders Althea Ducati will run a second rider for the first time this season after inviting Federico Sandi to compete alongside Carlos Checa at Imola.

Sandi competes with Althea in the Italian-based CIV Superbike Championship, the Italian taking his first win for the team at Vallelunga just over a week ago.

Sandi has also previously competed at World Superbike level, at Misano and Imola last season, albeit riding an Aprilia RSV-4 for Gabrielli Racing. On those occasions, Sandi scored a best finish of 13th.

Currently third in the CIV Superbike standings, Sandi will be joined on the grid at Imola by the two riders ahead of him, Barni Ducati's Matteo Baiocco and Alessandro Polita.

It'll be a third WSBK appearance of the season for Baiocco, who raced at Misano and Brno, and a second for Polita after he raced at Misano too.
