He went 2-for-4 in his first handful of opportunities and was replaced by left-hander Gregory Soto.The Pirates designated Santana for assignment in July after he posted a 6.05 ERA in 44 appearances out of the bullpen. He allowed eight home runs and walked 11.3% of the batters he faced."The stuff has ticked down slightly for Santana in 2026. He averaged a career-low 94.1 mph on his fastball. His slider sat at 85.6 mph, a 1.4 mph drop from 2025," Wright wrote. "The four-seamer/slider combo is Santanas bread and butter, but it performed poorly this year."MORE:Tigers receive lousy grade for Tarik Skubal trade to Dodgers from ESPNArizona is hoping Santana can regain the form that helped him post a 2.18 ERA in 70 outings with the Pirates in 2025, the best season of his career since debuting in 2018 with the Los Angeles Dodgers.Santana spent the past two and a half seasons with the Pirates after they claimed him off waivers from the New York Yankees in 2024.More MLB news:Cubs land Kevin Gausman in blockbuster trade with Blue JaysRed Sox expected to trade Jarren Duran during offseason, not MLB trade deadlineWhat did Mets get for Freddy Peralta?
