Ryan Atkins - a former Wakefield player - celebrated a late try with an interception
Warrington Wolves settled a high-scoring, entertaining final regular season game 36-23 against Wakefield to move into the play-offs with a win.
Ryan Hampshire's drop goal edged a 13-12 first-half in Trinity's favour, as both teams scored two tries apiece.
The second half remained a close affair until the visitors pulled clear late on to outscore Trinity by six tries to four in total.
Steve Price's Wolves face St Helens in their semi-final next Thursday.
Ben Murdoch-Masila and Toby King grabbed four-pointers in the opening 40, with Stefan Ratchford, Jack Hughes, prolific kicker Dec Patton and former Trinity centre Ryan Atkins completing the scorers.
Hampshire, who has now signed a new one-year deal at Trinity to end speculation surrounding his future, scored one of the four tries for Chris Chester's hosts, along with Tyler Randell, Joe Arundel and Ben Jones-Bishop.
Trinity could still yet finish fifth in the Super League, if Huddersfield are beaten at Catalans on Saturday.
