Returning to Flemington in September for the Group 1 Makybe Diva Stakes, he was first past the post for the fourth straight appearance at the track. Beating stablemate Black Heart Bart by a length, Zahra said, "He’s a genuine superstar. You’d love the Cox Plate to be here. The way he settled and found the line, there’s no reason why not to go for it. Today his turn of foot was electric." Palentino contested another three Group 1 races for the rest of the campaign, failing to finish better than 8th. Travelling to Sydney for the first time, he came last in the Epsom Handicap. Following its usual pattern of commencing a campaign with a shorter race, Palentino finished 4th in the 1200 metre Australia Stakes and then 4th again in the C F Orr Stakes. Back at Flemington for the Group 2 Blamey Stakes, Palentino won the race, 3 lengths ahead of favourite Tosen Stardom. Darren Weir noted, "Today he did everything perfect." In April 2017, Palentino was retired to stud. Its 2018 and 2019 stud fee was $17,600.
