The Black and Whites are still in contention for the treble after grinding out an 18-12 victory against Wakefield at the Rapid Solicitors Stadium.
Jamie Shaul looked to have crashed over but the try was ruled out the video referee confirmed he had been superbly held up over the line by Hall.
A Finn penalty established an 8-0 lead for Wakefield with seven minutes of the first half remaining.
Just as it looked like Wakey would go into the interval without conceding a single try, former Trinity player Danny Washbrook collected Tuimavave’s pass before touching down.
Marc Sneyd added the extras to bring the Airlie Birds back to within two points.
Shaul came up with a vital tackle early in the second half, holding up David Fifita over the line.
Sneyd nailed the conversion to send the Airlie Birds 12-8 ahead.
Hall continued to be instrumental for Trinity, picking out Johnson with aplomb who dived over acrobatically in the corner to level the scores.
Mahe Fonua put the Black and Whites back in front late on, going over in the corner out of dummy half after a great run down the line where he fended off several challenges from Wakefield players.
