Spezia staged a determined fightback after their nightmare start to Fiorentina, as they were 2-0 down within four minutes.
The Viola came flying out of the blocks with a German Pezzella header and Cristiano Biraghi finishing off good work from Pol Lirola.
However, Serie A newcomers Spezia showed great resilience to claw their way back into the match, equalising through Daniele Verde and Diego Farias.
The hosts could even have won it in stoppages with M’Bala Nzola, while Jose Callejon made his Fiorentina debut.
