Pitching Notes: Hernandez, Cordero, Lewis, Gonzalez

Diamondbacks reliever David Hernandez has a torn UCL and may require Tommy John surgery, Hernandez's agent Jason Hoffman tells FOX Sports' Ken Rosenthal (Twitter link).  Hernandez is getting a second opinion but if the original diagnosis is confirmed, the right-hander will miss the entire 2014 season.  Since coming to Arizona in December 2010 as part of the Mark Reynolds trade, Hernandez has posted a 3.42 ERA, 3.17 K/BB and 10.8 K/9, though he struggled a bit last season due to an inflated home run rate.  Losing Hernandez would further hurt the Arizona pitching staff, which also lost Patrick Corbin to an UCL tear earlier this month.

Here are some more notes about pitchers whose roster status is in question…

• Francisco Cordero has been told by the Red Sox that he isn't making the Opening Day roster, so the veteran reliever is now deciding whether to go to Triple-A Pawtucket or leave for another team, WEEI.com's Alex Speier reports.  While Cordero doesn't officially have an opt-out clause in his minor league deal with the Sox, the two sides have an agreement that Cordero would be released if he finds a job elsewhere.
• Colby Lewis can opt out of his minor league deal with the Rangers on April 10, Gerry Fraley of the Dallas Morning News reports.  Lewis was brought back on a minors contract after missing the entire 2013 season recovering from hip-resurfacing surgery, and the Rangers have been easing him back into action during Spring Training.
• If the Phillies are in need of another 40-man roster spot, GM Ruben Amaro said that Miguel Alfred Gonzalez could end up on the 60-day DL, Matt Gelb of the Philadelphia Inquirer tweets.  Gonzalez was officially placed on the 15-day DL (backdated to March 21) today due to tendinitis in his right shoulder.
