Local heroes Jon Rahm and Rafa Cabrera Bello will tee it up alongside defending champion Andrew Johnston when the Open de España gets under way on Thursday morning.
Spain's National Open returns to the European Tour International Schedule after taking a year off in 2017 and also comes back to the home of Spanish golf - Centro Nacional de Golf - a place Rahm knows well.
The two-time Rolex Series event winner combined his golf and studies here for two years and he is sure to attract a big crowd teeing off from the tenth at 08:55am alongside Cabrera Bello and Johnston.
Cabrera Bello arrives fresh from the Masters Tournament, just like Rahm, while Johnston is looking for a second European Tour title after his win in 2016.
The local duo of Adrian Otaegui and Pedro Oriol are sure to have a big following at 08:35am alongside Graeme Storm, as are Nacho Elvira and Gonzalo Fernandez-Castaño when they tee off with Ryan Fox at 1.35pm.
England's Matt Wallace will be aiming for back-to-back wins when he tees off at 08:45am in the company of local favourite Jorge Campillo and Dane Thorbjørn Olesen.
Alvaro Quiros - the 2010 champion - starts his campaign at 09:25am alongside Edoardo Molinari and David Lipsky while another Spaniard, Pablo Larrazábal, tees off alongside Paul Dunne and Eddie Pepperell at 1.55pm.
