Conor Jackson: Rapid Reaction

Maybe I’m missing something, but I don’t get the Conor Jackson trade. Granted, we’re not exactly giving up a ton in Jason Rice, a righthander originally out of the White Sox system. Rice has decent K rates – 9.39/9 and 89 in 85.1 IP this season in Pawtucket – but he walks too many (4.43/9) and 25 year old relievers who haven’t hit the majors yet aren’t in short supply.

That said, I’m not sure what the Sox see in Jackson. His career OPS numbers against LHP are better than McDonald’s – .825 to .789 – but Jackson’s having almost as tough a year as the bat he’ll presumably replace (or at least steal ABs from). His OPS against lefties this year is .686, while McDonald’s – his down year notwithstanding – is .768.

And then there’s defense. Fox’s Jon Morosi says the Red Sox envision Jackson playing a super utility role, bouncing between the outfield and infield. By reputation, Jackson’s not a stellar defender, having spent most of his career in left or at first base. The metrics bear this out, at least for this season. Though it’s foolish to place too much emphasis on single season defensive metrics, let alone partial season, McDonald grades out at 14.9 on UZR/150 this season, against Jackson’s 8.8.

As far as total value goes, WAR doesn’t love either player, though Jackson edges McDonald’s .3 with a .4.

We didn’t give up much, then, but it’s not clear that we got much in return. At his peak, Jackson was a useful 3 win player – a number McDonald won’t touch in his career. But that was three years ago and his decline hasn’t been gradual.

My guess is that the front office has identified something specific they like about the player – recent adjustments, a track record of success amongst possible playoff opponents (lifetime .714 OPS against the Yankees, .697 Texas, .932 Detroit) – something. It may be his versatility as Morosi claims, but I’m not quite sure I understand that; last I checked we’ve got three guys who can play first base, and five who can play the outfield (assuming Drew does come back). Or they know that Drew actually broke his finger and isn’t coming back.

And I’m sure that, as always, they weighed the cost and found it acceptable. Personally, I’m not for or against the transaction; I merely fail to understand it. Either way, it will be interesting to see how this plays out in terms of playing time.

  1. It's certainly about depth. I'm just wondering why they focused on Jackson, and why they gave up at least a filler arm in Rice. I suspect that they know something I don't, and I'm curious as to what that is.
