Rangers Ace Jacob deGrom to Undergo Tommy John Surgery, Miss Remainder of Season

DeGrom signed a five-year, $185 million contract with the Rangers in free agency but made only six starts before landing on the injured list.
An MRI revealed significant damage in deGrom's right elbow, requiring Tommy John surgery and ending his season.
DeGrom previously had Tommy John surgery in 2010 when he was a prospect in the Mets organization.
The Rangers led the AL West despite deGrom making only six starts, but his absence leaves a hole in their rotation.
The Rangers could look internally, at prospects or on the trade market to replace deGrom for the rest of this season and likely much of next.
