Finnegan has the best season of his career in 2025. It didn't start that way with the Washington Nationals, as his 4.38 ERA was tracking to be the worst of his career, while on the brighter side, his FIP sat at 3.65. After 39 innings pitched, Finnegan was traded ahead of the 2025 trade deadline to the Detroit Tigers. It was in the Motor City where the 34-year-old excelled.
Still, the Blue Jays are certainly in the market for a high-leverage reliever, with Seranthony Domínguez reaching free agency. There'd be immense upside by signing Díaz, who's coming off another sensational performance in 2025, where he logged 28 saves in 31 attempts and pitched to a dominant 1.63 ERA (second-lowest among qualified major-league relievers) as well as a 2.28 FIP, striking out 38 per cent of his batters faced (second-highest among MLB relievers).
