Mengden, the kid with the Rollie Fingers stache, who will turn 24 later this month, will no longer be in the running for the fifth spot in the Oakland Athletics rotation in 2017.
Unfortunately, Mengden injured his foot during a bullpen session on January 31 and was forced to undergo surgery to correct the injury.
As you can imagine, it only gets worse for the young player from there. He apparently fractured the medial tibial sesamoid bone.
A’s Dr. Kevin Varner performed the surgical procedure which included a sesamoidectomy, or the complete removal of the sesamoid bone.
