9:29am: A National League team was awarded the claim on Byrd, according to Jon Heyman of CBS Sports.
8:58am: Marlon Byrd has been claimed off revocable trade waivers by an unknown team, according to Adam Rubin of ESPNNewYork.com (Twitter link). Not long ago, this wouldn't have seemed as newsworthy, as the Mets had been steadfast in their stance against trading Byrd. However, as Rubin reported earlier this morning, the Mets are likely to make at least one trade in the next 24 to 48 hours.
Byrd, who turns 36 on Friday, is enjoying a surprising career year with the Mets. His 21 homers are a career-high, as is his 136 OPS+, and his .285/.330/.522 batting line has made him one of baseball's most productive right fielders. His defense grades out well in right, and he's owed just $130K for the remainder of the season.
The Mets will have 48 hours to work out a trade with the claiming team, so the latest we could find out resolution on the situation would be Thursday. Prior to the July 31 non-waiver trade deadline, the Reds, Pirates and Orioles were among the teams to show interest in Byrd.
