Patrick Corbin (SP-ARZ)

Injury – He has been diagnosed with a partially torn ulnar collateral ligament in his left elbow.  Corbin will be getting a second opinion from Dr. James Andrews before deciding whether to attempt rehab or go through with Tommy John surgery.

2013 Season – After almost not even making the Diamondbacks' roster out of spring training, Corbin started the season 9-0 as and made the National League All-Star team as a rookie.  He finished his rookie campaign with record of 14-8 and an ERA of 3.41.

Reason For Optimism  

  • He didn't feel anything pop in his arm and is still holding out hope for rehab.
  • Even if he does need Tommy John surgery, he is young enough (24) where he has plenty of time to come back and be an effective pitcher by 2016.
  • After such a strong rookie season, he is still worth keeping in deep dynasty leagues.
  • Two of his teammates (Daniel Hudson and Matt Reynolds) have already undergone Tommy John surgery and can offer advice and empathy for what he will likely go through.

Reason For Concern

  • Tommy John surgery is a major operation which typically requires at least 12 months of recovery.
  • If he tries to rest and rehab, he could only be putting off the inevitable which could prevent him from being ready by 2016..
  • While many pitchers have come back successfully from Tommy John surgery, there are several that have had re-occurrences which require a second surgery (including his teammate Daniel Hudson)..

2014 OUTLOOK – Corbin was a solid fantasy option as Arizona's number one starter coming off of a very productive rookie season.  Clearly this injuries diminishes his value, especially in redraft leagues.  If you are drafting before a decision is made on whether he has surgery, err on the side of caution and do not select him until at or near the end of your draft.  If your keeper league has contract limits, then you may want to consider setting him free.  Chances are that he will opt for surgery and miss the entire season.
