Frank and Faye Drummond are banking on a change of environment to get their group one performer El Pescado back to his best.
The Waikato breeder-owners, who stand his sire El Hermano at their Cheval Stud, have moved last year's Makfi Challenge Stakes runner-up from Stuart Manning's Tauranga stable to Opaki trainer Polly Macdonald.
"The horse has gone off and he's just not racing to what we know he is capable of," Frank Drummond said.
"We've gone for a change of scenery and we'll see what that does. Stu is a very good trainer and it's no reflection on him - he's done a great job for us."
Macdonald currently also has the multiple winner El Bayardo in work for the Drummonds.
