(670 The Score) The Cubs on Tuesday claimed right-hander Kervin Castro off waivers from the Giants, then optioned him to Triple-A Iowa.
The Giants designated the 23-year-old Castro for assignment Monday. He had made just two appearances for San Francisco this season, allowing a combined five earned runs in 1 2/3 innings. Castro had a strong debut campaign for San Francisco in 2021, as he didn’t allow an earned run in 13 1/3 innings across 10 appearances.
Castro had a 5.57 ERA in 29 games at Triple-A Sacramento this season. The Giants signed him as an international free agent in 2015 out of Venezuela. He entered the 2022 season as the No. 19 prospect in the Giants’ farm system, according to MLB Pipeline.
