Manly returned to the top of the NRL ladder on Sunday but were less than convincing in a 15-12 win over the struggling Gold Coast Titans.
The Sea Eagles, who went into the game on the back of a 24-4 defeat to second-placed South Sydney last week, overcame a dogged Titans side being coached by Neil Henry for the first time.
Tries from Kieran Foran and Brett Stewart paved the way but it was a late Daly Cherry-Evans field goal that sealed the two points, just before Kalifa Faifai Loa crossed late for the hosts.
