Former top prospect Fernando Martinez and left-handed reliever Danny Herrera are on waivers, according to Adam Rubin of ESPNNewYork.com. The Mets need to clear 40-man roster space for Scott Hairston and Ronny Cedeno.
Martinez, 23, has a .183/.250/.290 line in 145 plate appearances with the Mets since 2009. He spent most of the 2011 season at Triple-A, posting a .260/.329/.417 line with 19 extra base hits in 250 plate appearances. Baseball America named him one of the top 100 prospects in the game before each of the 2007-10 seasons.
Herrera, 27, joined the Mets in last summer's Francisco Rodriguez trade. The sidearmer pitched 9 2/3 innings in the Major Leagues in 2011 and spent most of the season at Triple-A. He posted a 2.20 ERA with 7.9 K/9 and 2.2 BB/9 for the top affiliates of the Brewers and Mets. He can declare free agency if he clears waivers.
