The Pirates have announced that Jameson Taillon will undergo Tommy John surgery. Taillon's ulnar collateral ligament was "compromised," GM Neal Huntington told reporters, including the Tribune-Review's Karen Price. "As we walked through the process with Jameson, educated him, he's a smart young man and we walked through it with his family and representatives," said Huntington. "He felt this was the best course of action to get back to full health and stay healthy a long time." Taillon, the No. 2 overall pick in the 2010 draft, typically ranked second on lists of the Pirates' top prospects, behind outfielder Gregory Polanco. Taillon had been expected to contribute down the stretch this season, and his absence will take a toll on the Pirates' pitching depth behind starters Gerrit Cole, Francisco Liriano, Charlie Morton, Wandy Rodriguez and Edinson Volquez. Here are more notes on injured pitchers.
- The Pirates aren't the only team to lose a pitcher to Tommy John. The Mets have announced that Bobby Parnell will undergo the surgery as well. Parnell's surgery will be performed Tuesday. Parnell was among the Mets' top relievers in 2013, posting a 2.16 ERA with 7.9 K/9 and 2.2 BB/9 and serving as their closer for part of the season.
- If the Mets look outside the organization for relief help, they could turn to Joel Hanrahan, Ryan Madson or Kevin Gregg, Jon Heyman of CBS Sports tweets. Hanrahan and Madson, of course, are coming off injuries of their own — Hanrahan had surgery last May to repair a torn flexor tendon, and Madson has missed the last two seasons with arm trouble.
