Castro allowed two earned runs on three hits over two-thirds of an inning in Monday's 8-3 win over the Tigers. Castro was the first in a parade of relievers called upon following emergency starter Raul Alcantara's exit after 3.2 innings. The hard-throwing right-hander disposed of James McCann to finish out the fourth, but ran into trouble in the fifth by allowing RBI doubles to JaCoby Jones and Ian Kinsler. The results were par for the course for Castro, who's now surrendered a pair of earned runs in each of his last three appearances. Castro's rough stretch has bumped up his ERA from 2.88 to 4.55, even as he's generated an impressive nine strikeouts across 8.1 innings over that span.
Castro fired two scoreless innings in Tuesday's 8-2 loss to the Angels, allowing one hit and three walks. He struck out two. The hard-throwing right-hander's final line represented a much-needed bounce-back from the four earned runs he'd surrendered over his previous trio of appearances. Castro did issue multiple free passes for the first time this season, but he also recorded multiple whiffs for the third straight outing. Despite his recent stumbles, his solid 3.09 ERA, 1.03 WHIP and 21 strikeouts over 23.1 innings are helping to keep him relevant in deeper formats.
Castro (1-2) gave up a game-winning solo home run for his only hit and earned run over two-plus innings in Wednesday's 8-7 extra-inning loss to the Orioles. He also issued a walk and recorded three strikeouts. Castro otherwise turned in a dominant 33-pitch appearance, but his one mistake against Manny Machado cost the Athletics the game. The 29-year-old right-hander has been scored upon in three straight appearances, allowing a total of four earned runs over the five innings encompassing that stretch. Although his ERA (3.43) and WHIP (0.95) remain solid, thanks to his performances earlier in the season, he's trending in the wrong direction as of late.
Castro worked a scoreless seventh inning in Monday's 6-2 loss to the Royals, allowing a hit and a walk. The hard-throwing reliever has mostly been dominant over his last 10 appearances, giving up three runs (two earned) over 14.1 innings while generating a .143 BAA and allowing a .182 wOBA.
Castro fired 2.1 scoreless innings in Sunday's 6-5 extra-inning win over the Twins, allowing a hit and a walk while recording three strikeouts. Castro has posted back-to-back scoreless efforts of at least two innings, allowing just a hit and a walk while notching five strikeouts. The 29-year-old right-hander boasts a wicked mid-90s fastball that affords him significant strikeout upside, and that could lead to some closing opportunities, given Santiago Casilla's inconsistency in the ninth-inning role.
