Mets only view Herrera as second baseman

NEW YORK -- Although Dilson Herrera has appeared in 27 minor league games at shortstop this season, Mets brass only views him as a second baseman, and his audition will be limited to that position, a team insider said.

The source also cited three reasons the 20-year-old Herrera was selected over Matt Reynolds, who is hitting .336 with five homers and 38 RBIs in 256 at-bats since a promotion to Triple-A Las Vegas:

-- Herrera needed to be added to the 40-man roster, whereas Reynolds does not.

-- The Mets want playoff-bound Las Vegas to be best equipped to win the Triple-A championship.

-- Reynolds is getting his reps at shortstop, and the need is at second base with Daniel Murphy landing on the DL with a strained right calf.

A team official did not agree that Herrera's call-up could help fuel a winter trade of Murphy. The source noted Herrera is only 20 and Murphy was leading the NL in hits when he landed on the DL,which would be difficult to replace. So the Mets, while receptive to trading Murphy, are not particularly eager without a proper return.

On other Mets-related topics:

• A team insider said the trade front was not active for Bartolo Colon or any other Mets player who had cleared waivers. So unless another team ups its dialogue this weekend, the likelihood appears Sunday's deadline will pass without Colon getting moved.

• On the Travis d'Arnaud to left field chatter, a team official noted there was no dialogue among Sandy Alderson and his top deputies. It merely was an internal conversation between Terry Collins and his staff.

The source wouldn't discount Alderson at least internally debating a move from catcher at some point. Still, the source agreed with the ESPNNewYork.com premise that d'Arnaud's offensive production makes him attractive at catcher and ordinary in the outfield, which means a shift is not foreseeable.
