The Philadelphia Phillies claimed right-hander Max Castillo off waivers from the Boston Red Sox on Wednesday.
In a corresponding move, the Phillies designated outfielder Simon Muzziotti, 25, for assignment.
Castillo, 24, was 0-1 with a 4.43 ERA in 20 1/3 innings over seven relief appearances with the Kansas City Royals last season. The Venezuela native made his major league debut in June 2022 with the Toronto Blue Jays before a trade to the Royals in August 2022.
For his career, Castillo is 0-3 with a 5.43 ERA, 47 strikeouts and 24 walks in 59 2/3 innings over 21 games (six starts).
Boston had claimed him off waivers from Kansas City on Jan. 2 then designated him for assignment on Feb. 2 when catcher Tyler Heineman was acquired from the New York Mets.
