Two-time Cy Young Award winner Corey Kluber will be out at least the next four weeks after suffering a Grade 2 teres major tear in his right shoulder.
Kluber only last one inning in his debut with the Texas Rangers on Sunday before being pulled after feeling tightness in his shoulder during the inning. The examination on Monday revealed there was a muscle tear and will now sideline him for the immediate future.
The 34-year-old will undergo a PRP (Platelet-Rich Plasma) injection and will be shutdown the next four weeks before being re-evaluated by the Rangers medical staff. If he does return this season, it more than likely be in a relief role.
Kluber was acquired by the Rangers in the offseason from the Cleveland Indians after spending nine years with Cleveland winning two Cy Young Awards in 2014 and 2017 and also appearing in three All-Star games. Last season was also derailed with injuries after Kluber fractured his forearm after a line-drive hit against Miami and then suffering a strained oblique while rehabbing last August.
He was the expected third man in the Rangers rotation behind Lance Lynn and Mike Minor. Now with Kluber sidelined, it’s expected that Koby Allard, who went 4-2 with a 4.96 ERA in nine starts last season for Texas will take Kluber’s spot in the rotation.
