The Mets have announced that C Rene Rivera was claimed off waivers by the Chicago Cubs.
In 54 games this season, the 34-year-old is hitting .230 with eight homers and 23 RBI.
With Curtis Granderson traded to the Dodgers as well, the Mets have recalled LHP Tommy Milone and C Kevin Plawecki.
Milone, who came to the Mets from the Brewers early this season, has been on the DL with a knee injury since May. He began a rehab assigned with the Gulf Coast Mets back at the end of July.
The 30-year-old started four games with the Mets, going 1-0 with a 4.95 ERA this season.
Plawecki, who has only seen 10 big league games this season, was last with the Mets in late May. He went 3-for-24 with four RBI in that span.
In 64 games with Triple-A Las Vegas this year, Plawecki is hitting .328 with nine homers and 45 RBI.
