It was announced last night before the Pirates’ ultimately losing game against the Giants that rookie reliever Yerry De Los Santos’s season was over after being placed on the 60-day IL with a right shoulder latissimus dorsi muscle strain.
De Los Santos was coming into middle- or late-relief situations, and while he wasn’t setting the world on fire, he was doing what was asked of him. Before the Arizona game on Thursday, where it was first noticed something was off, he had posted a 3.51 ERA and 3.67 FIP across 25 2/3 innings, with 26 strikeouts to eight walks.
