Silvas began his collegiate career at Division I California Baptist, where he spent one season in 2022. He made 15 appearances and six starts on the mound, pitching 28 innings, as he logged a 2-3 record with a 7.71 ERA. Silvas transferred to Riverside City College for 2023 and took off. He played and started in five games, holding a 1.44 ERA, while striking out 33 batters in 25 innings pitched. His time at RCC was enough to get him drafted in the 16th round to the Minnesota Twins during the 2023 MLB Draft. Silvas did not appear in any games in the Twins organization and was released in February.
