Gregory Santos

Santos was designated for assignment by San Francisco last off-season, only to be acquired by the White Sox soon afterwards. Despite having minimal experience at the big-league level, the hard-throwing right-hander made Chicago's opening day bullpen. He spent the first two months working in low leverage, but his solid body of work, good control (5.9% walk rate) and excellent slider (.196 BA, 37.5% whiff rate) earned him higher-leverage opportunities as the season went on. The 24-year-old converted his first save in early July, then stepped into closing duties once Chicago unloaded their veteran relievers at the trade deadline. Santos totaled five saves before right elbow inflammation ended his season in mid-September. He was expected to open 2024 as the White Sox's primary closer but was dealt to Seattle in early February, where he likely won't have much fantasy value in a significantly better bullpen.
