SEATTLE — The Red Sox have designated outfielder Darnell McDonald for assignment to make room for Josh Beckett on the roster, a team source confirmed this afternoon.
Globe colleague Nick Cafardo reported earlier today that McDonald would be part of the roster move. Then McDonald put this message on Twitter: "Dream come true to play in Boston. Want to wish my boys good luck the rest of the year! Much love to RSN! #ShowGoesOn"
McDonald, 33, hit .252/.323/.413 over 234 games with the Red Sox starting in 2010 when he made the team out of spring training as a minor league free agent. But he hit .228 with a .695 OPS the last two seasons.
The righthanded hitting McDonald hit .214 against lefthanders this season.
The arrival of Brent Lillibridge cost McDonald a roster spot along with the play of Daniel Nava and Ryan Kalish.
The Sox now have 10 days to trade, release or pass McDonald through waivers.
McDonald was nearly designated on June 14, 2010 at Tampa Bay. But the Sox make it a practice not to formalize roster moves until batting practice and Jacoby Ellsbury felt pain in his ribs, saving McDonald from being let go.
He was in his hotel room watching a movie at the time and returned to Tropicana Field. But there is unlikely to be a reprieve this time.
