Mets sent RHP R.J. Alvarez outright to Triple-A Syracuse.
Alvarez went unclaimed on waivers after being designated for assignment last week. The 31-year-old righty was up briefly for the Mets in early July, but never made it into a game for New York. He’s recorded a solid 3.16 ERA, 1.44 WHIP and 33/19 K/BB ratio across 31 1/3 innings (26 appearances) this season at Triple-A Syracuse. He last appeared in the majors back in 2015.
