Shapovalov was outclassed 6-2 6-4 by former US Open victor Juan Martin del Potro in Wednesday's Classic second round, and will now head to Melbourne.
There were no break points in the first set but the Argentinian managed to break the Russian's first serve in the second set and felt it was an encouraging performance ahead of facing Ferrer .
Shapovalov had defeated the 2009 U.S. Open champion in the second round of the Rogers Cup in Montreal last August.
"I didn't expect to play at this level in the first match of the year".
But it was Del Potro who was the more clinical in taking his chances, coming through to claim a 6-4 6-4 triumph that sets up a showpiece with another Spaniard, Roberto Bautista Agut.
"I tried to not make mistakes, play in the right places, try and play as hard as possible with all the pressure", Bautista Agut said of the third-set tiebreak.
"It's incredible to me just to be playing tennis against after all my wrist problems".
Earlier, fifth seed Bautista Agut outlasted Dutchman Robin Haase in an epic clash that took nearly three hours before the Spaniard produced an audacious backhand lob that kissed the baseline to clinch the 6-7 (7) 7-6 (3) 7-6 (5) win.
"Tomorrow I'll have to run even more against David but it's a good challenge for me, to see how my body is before an important event like the Australian Open".
"I'm just so happy that I have won".
Bautista Agut booked his spot in the Classic final with a 6-7 (7-9) 7-6 (7-3) 7-6 (7-5) win over the journeyman Haase, battling from beginning to end.
"I passed really bad moments on the court and in that moment, I scream because I was very stressed", the world No.21 Bautista Agut said.
