The Toronto Blue Jays face a significant setback as pitching prospect Adam Macko is diagnosed with a probable meniscus tear in his knee, requiring surgery and expected to sideline him for an extended period. Macko was projected to start the season at Triple-A Buffalo and was seen as a vital option for the big league rotation following an uneven minor league season, where he recorded a 4.87 ERA at Double-A New Hampshire. His injury further strains an already depleted pitching depth chart for the Jays, who also have fellow prospects Ricky Tiedemann, Brandon Barriera, and Landen Maroudis likely sidelined for most of the season. The team anticipates that Yariel Rodriguez will take on a larger role as a swingman, with Jake Bloss emerging as a primary starter option in Buffalo. Meanwhile, the Jays have recently bolstered their bullpen by signing veteran arms Amir Garrett and Jacob Barnes, who will compete for spots in spring training.
