Mike Carp has been designated for assignment, with the Red Sox calling up Mookie Betts to take his place on the active roster.

While Carp had requested a trade from the Red Sox over the All-Star break, as always, it takes two sides to make any deal work. It appears there were no takers for the young first baseman/corner outfielder, which is not terribly surprising given his line of .198/.320/.279 in 86 at bats this season.

In 2013, Carp proved a valuable bat off the bench, hitting .296/.362/.523 as he helped the Red Sox return to the World Series, but while the team bent over backwards to keep him on the roster over the offseason, they didn't really have a role for him to play regularly, particularly with last year's results not forthcoming. With Allen Craig recently added to the mix, there really wasn't much room for him anymore even if he wanted to stay.

We'll always be left to wonder what the offseason offers were like for Carp that the Red Sox passed up on in order to hold onto his power, but that's all in the past. For now, the Sox have Mookie Betts back with the team and the last loose thread from the trade deadline sorted out.

Betts will bat ninth Friday night against the Yankees, playing center field.
