The Mets have traded RHP Gabriel Ynoa to the Orioles for cash considerations, the team announced Friday.
With the move, the Mets' 40-man roster is at 39.
The Mets will need a 40-man roster spot when the re-signing of RH reliever Fernando Salas becomes official.
Ynoa, 23, had a 6.38 ERA (2.60 FIP) and 1.80 WHIP while striking out 17 batters in 18 1/3 innings (three starts, seven relief appearances) for the Mets last season.
He had a 3.97 ERA and 1.36 WHIP in 154 1/3 innings last season for Triple-A Las Vegas.
