Monell is not on the 40-man roster, so the Mets will have to open a spot on it when they select his contract from Triple-A Las Vegas.
Unless there is a move, he would become the third catcher along with Anthony Recker and Kevin Plawecki while starter Travis d'Arnaud is on the disabled list after breaking a finger April 20. Monell is hitting .397 with four homers and 15 RBIs at Las Vegas.
Also, Texas returned right-hander Logan Verrett to the Mets, who sent him outright to Las Vegas. The 25-year-old was taken by Baltimore in the winter meeting draft and claimed by the Rangers. He was 0-1 with a 6.00 ERA in four games and nine innings for Texas, which designated him for assignment April 24.
