Any day now the email labeled “Red Sox Announce Roster Moves” will arrive from the PR staff with the news fans are dying to hear: Xander Bogaerts has been promoted.

The slugging third baseman is the most exciting homegrown position prospect of the last 40 years more exciting than Nomar Garciaparra more exciting than Wade Boggs (who wasn’t all that exciting until he got here) more exciting than Jacoby Ellsbury Dustin Pedroia and anyone else you can name.

We probably must rewind to 1975 and the twin arrivals of Fred Lynn and Jim Rice to find prospects as anticipated as Bogaerts who is posting the kind of numbers in the minors that scream future superstar.

The Red Sox as currently constituted are one proverbial piece away. Jake Peavy should stabilize the rotation. The emergence of lefty Drake Britton and righty Brandon Workman has the potential to do the same in the bullpen.

Where can the Red Sox upgrade then? With a right-handed bat and third baseman.

Enter Bogaerts. The 20-year-old with the advanced approach has played shortstop throughout the minors and he’s now getting reps at third base for Triple-A Pawtucket where he entered the night hitting .277 with eight homers and 25 RBI in 48 games. He has an .841 OPS despite being one of the youngest players in the International League just as he was one of the youngest players in the Double-A Eastern League where he hit .311 with six homers and a .909 OPS.

With the trade deadline gone adding an impact player in August will require a waiver transaction and those are never guaranteed.

All it will take to add Bogaerts however is a spot on the 40-man roster. No complicated deals that could be mucked up by a waiver claim and no need to part with a prospect of any value.

And then things could get really interesting. There are no guarantees of course particularly with 20-year-olds making their big league debuts in the heat of a pennant race. But look at it this way — will a legit contender make a more intriguing addition over the next two or three weeks than Bogaerts?

Miguel Cabrera arrived for the second half of the 2003 season with the Marlins blasted 12 homers as a 20-year-old and ended up helping the team win a World Series while earning a couple of MVP votes. That’s a best-case scenario.
