Juffs Crossing had ordinary form going into the race but when he landed in the "death" outside of the leader and favourite Precious Dragon after having to work hard three-wide in the early stages.
Most punters expected Mackrill's gelded six-year-old to drop off when the pressure was applied turning for home but instead he gave his all and edged out Boltnmach and Precious Dragon in a slog-fest style finish.
``His form hasn't been as bad as it might look on paper,'' Mackrill said.
``He hasn't been scoring up (behind the mobile) in his recent races."
``But tonight he got a good run through early and ended up outside the leader," he said.
Juffs Crossing (-Power Full Miss) was well driven by John Walters who landed a double when he guided Karalta Dazzler to victory in the following race.
Mackrill doesn't have a huge opinion of Juffs Crossing but he does think he is capable of winning a couple more races.
``They ran along a bit tonight which suited him because he's a big one-paced plugger," Mackrill said.
``He's got no sprint but he will keep grinding."
``He can run 30-seconds quarters (400m) and keep running them.''
While failing to score up at the start was a problem, Mackrill also explained that the horse had his share of bad luck in recent races.
"Whendrove him here a couple of starts ago, he was held up and never got a crack at them,'' the trainer said.
``We actually fancied him a bit tonight," he said.
