Fantilli produced two assists and three shots on goal in Tuesday's 3-1 preseason win over the Blues.
Fantilli set up Yegor Chinakhov's power-play goal in the second period and Mathieu Olivier's empty-netter in the third. With four goals, two helpers and 10 shots on net over four preseason contests, Fantilli has made a great impression. He had 12 goals, 15 assists, 115 shots and 63 hits over 49 regular-season outings before a lacerated calf ended his season early in 2023-24, but the 19-year-old looks poised for a bigger breakout in Year 2.
