According to Ken Rosenthal, the Red Sox have added to their outfield depth today.

Chris Young the hitter is one of the better fourth outfielders in baseball today, combining the ability to play all three outfield spots with some lefty-mashing abilities, making him a very nice platoon partner and capable reserve who won’t drag the offense down too far if pushed into regular duty. He gave the Yankees 350 quality plate appearances in just that role last year, putting up +1.2 WAR as a useful part-time player, and now he’ll take his skills to Fenway Park to provide depth behind the young OF trio of Rusney Castillo, Mookie Betts, and Jackie Bradley Jr.

With Betts and Castillo both being right-handed, it would seem that — barring a trade — most of Young’s playing time may come as part of a job-share with Bradley. Or, alternately, the team could be looking at trading Rusney Castillo and replacing him with a left-handed hitting outfielder; they’ve been rumored to have interest in Alex Gordon and Jason Heyward at different points this winter, and while you’re not going to platoon either of those guys, having Young around would be more useful if two of the three OFs were lefties.

Or, potentially, they just might like Young’s fit in their ballpark. After all, he’s about as extreme a pull hitter as there is in baseball.

Young is also one of the game’s most extreme fly ball hitters, and since Fenway inflates the value of fly balls to left field, Young’s skillset could work better in Boston than places without a Green Monster to bounce balls off of. So perhaps this isn’t as much about a roster fit as it is a skillset fit.

We don’t have terms of the deal just yet, but the FG crowd had Young down for a two year, $12 million deal in the crowdsourcing project, which sounds about right to me.
