Brady Aiken, the lefthanded pitcher taken first overall by the Houston Astros in the 2014 draft, but who was unable to agree to a deal with the Astros, has undergone Tommy John surgery.
Aiken pitched for the first time this season six days ago, but was pulled after only 13 pitches, without there being, prior to now, a definitive answer as to why he was pulled.
Aiken and the Astros had agreed to a $6.5M bonus last summer, but the Astros pulled that offer after doing a physical on him. Aiken was considered the top overall player in last year's draft, and was thought likely to go in the top five in this year's draft prior to undergoing surgery.
Even having undergone Tommy John surgery, Jim Callis notes in the story linked above that Aiken is still expected to go high in the 2014 draft. The Rangers' selection is #4 overall, and Aiken will presumably be one of the players they'll be strongly considering with their selection.
