Yates succeeds Roglic
Yates seized power in the fifth of eight stages.
He then won a mountain stage and took the lead in the standings from Michael Woods.
As the winner of the Tirreno, Yates succeeds Primoz Roglic, who narrowly beat Yates' twin brother Adam last year.
Roglic is currently wearing the yellow jersey in the Tour de France.
The Italian stage race is normally held in March in preparation for the Giro d'Italia.
