Falter was added to the Phillies' 40-man roster Friday, Meghan Montemurro of The Athletic reports.

Falter pitched for Double-A Reading in 2019, posting a 3.84 ERA and 1.26 WHIP over 77.1 innings. He wasn't included in the Phillies' 60-man roster pool in 2020, but he'll be protected from the Rule 5 draft as part of the 40-man roster.
