The Boston Red Sox and Los Angeles Dodgers are apparently working on a huge trade that could involve as many as nine players, set into motion by the Dodgers’ claiming Adrian Gonzalez and Josh Beckett on waivers earlier Friday.

There have been multiple signs of this deal coming to fruition; here are some of them:

OFFICIAL: @dodgers today recalled outfielder/infielder Alex Castellanos and optioned right-handed pitcher Rubby De La Rosa to AAA Albq.

De La Rosa had just been recalled and made one appearance; sending him back down would allow him to be a player to be named later in the deal.

And two major-league players who could be in the deal have been taken out of Friday night lineups:

According to a tweet from WEEI’s Alex Speier, both Gonzalez and Nick Punto were “summoned into the clubhouse”. Punto could also be involved in this trade.

Finally, this photo on Instagram, linked on this tweet, purports to show a poster of Adrian Gonzalez being removed from an office corridor at Fenway Park.

Looks like A-Gonz is A-gone. Stay tuned for more.
