The Pittsburgh Pirates signed Dilson Herrera in 2010 as an amateur free agent. The Mets acquired Herrera on August 27, 2013 in the trade that sent John Buck and Marlon Byrd to the Pirates.
After being assigned to AA Binghamton during spring training, Herrera was promoted to AAA Las Vegas on April 7. The Mets called up Herrera on May 1, appearing in 10 games before being placed on the Disabled List on May 15 with a broken finger. Herrera returned to the Mets on June 11 and played in another 15 games before being optioned back to Las Vegas. Herrera finished out the season as a September call-up. For the year, Herrera hit .211 with 3 Home Runs but was able to work out 11 walks to give himself an OBP of .311. Defensively, Herrera committed only 2 errors in 31 games to help his .986 fielding percentage. Those numbers were slightly better than Daniel Murphy’s 6 errors and .979 fielding percentage at the position for 69 games.
Herrera is signed for 2016 on a one-year contract, earning $507,000. He is under team control until 2018, and Arbitration-eligible from 2019 through 2021.
Herrera was the main reason for Murphy not being re-signed. Herrera is being tagged as the “second baseman of the future, and Murphy would have required a 3 year investment, thus preventing Herrera from coming up this season or in 2017 at the latest. Neil Walker was signed as a one-year player to essentially keep the spot warm for Herrera.
Herrera should have a good chance to make the major league club out of spring training, but I would not be surprised to see him start the season at Las Vegas. This may be due to the fact that he still could use some work to get ready, and there are capable backups for Walker in Ruben Tejada and Wilmer Flores. If he is not on the opening day roster, he is a prime candidate to be called up in the event of an injury.
Tradable or Untradeable?
Given that Herrera is very high on the Mets list, and his designation as the starting second baseman beginning in 2017, he is one of the players on the roster deemed untradeable.
