Riddle was acquired from the Reds in a small trade back in May and didn't end up making an appearance for the Mets. The 31-year-old journeyman offers some defensive versatility and could wind up landing somewhere this offseason as organizational position player depth.

Riddle was assigned to Triple-A after passing through waivers in April. He'll go to the Mets and serve as outfield depth. The 30-year-old outfielder was hitting just .208/.250/.365 with three homers across 104 plate appearances in Triple-A. 

Riddle was designated for assignment on Tuesday and passed through waivers unclaimed. The versatile 30-year-old owns a rough .223/.261/.354 batting line in 797 career major league plate appearances.

Riddle was up for a handful of games with the Reds after Jonathan India and Mike Moustakas sustained injuries earlier this month. There's a strong possibility that he passes through waivers unclaimed and remains with the organization.
