On the day Mancini extended his contract until after the 2026 World Cup, the Azzurri head coach confirmed a first group to face San Marino in a May 28 friendly.
Italy have to trim that selection to 26 men for the rescheduled European Championship finals, with a second warm-up fixture following against the Czech Republic on June 4.
Raspadori will hope he can impress Mancini in order to play a part having come to the fore for Sassuolo since the March international break.
The 21-year-old had a goal and an assist across just 110 minutes in the European Under-21 Championship group stage during that period, having only made his Italy U21 bow in September.
