May 1, 2025 9:37 PM : Slaten (0-2) was charged with the loss and a blown save in Thursday's 4-2 defeat to the Blue Jays, allowing three runs on three hits and one walk with no strikeouts in one inning.
Analysis: One game after giving up the game-ending run, albeit one that was unearned in extra innings, Slaten's showing Thursday was far less excusable. The right-hander gave up a go-ahead three-run home run to Vladimir Guerrero in the eighth inning, taking his first blown save of the season. Slaten now holds a 5.56 ERA, 1.15 WHIP and 9:5 K:BB over 11.1 innings this season, though he's been charged with an earned run in just two of his 13 outings.
