Jordan Danks down because Moises Sierra might be a better hitter

There was probably some amount of rejoicing among White Sox fans when Jordan Danks and his .098/.229/.195 batting line were demoted to Triple-A Charlotte earlier this week.

The White Sox recently added Moises Sierra to their roster.

Danks has a glove that can carry him as a fifth outfielder on the roster of a good team. He's also made enough slow, steady progress through the minors offensively that he's earned an extended big-league look under the right circumstances. Those circumstances include a wave of injuries to the Sox outfield, and frankly a lack of better options.

Two things mucked up Danks' big opportunity. First there was his awful showing at the plate, which would have been too much to stomach even if the Sox were 10 games or so under .500 and more squarely in "playing for next year" mode. The second thing is the pickup of Moises Sierra off waivers from the Blue Jays.

Sierra didn't end up on waivers because he's much of a prospect. He ended up there because he spent his time in Toronto this year making Danks look like Mike Trout with his .059/.086/.059 "hitting" performance. And Sierra can't play center field.

In Danks and Sierra we're still talking about two guys who have combined for 629 sporadic big-league at-bats, so we should probably look at what they've done in the minors to get a better idea of who might hit better.

Player	PA	BA	OBP	SLG	K%
Danks	2,079	.266	.353	.423	27
Sierra	2,859	.266	.329	.408	20

Their overall work makes Danks look like a better player, but that's not really fair to Sierra, who began playing ball as a 17-year-old free agent out of the Dominican Republic. Danks was drafted out of college and began as 21-year-old.

So here's what they've done in Triple-A:

Player	PA	BA	OBP	SLG	K%
Danks	1,566	.265	.350	.422	28
Sierra	834	.275	.343	.447	23

Now three things jump out at you. The first is that Danks has played A LOT more games at Triple-A than Sierra. Which makes sense because Danks is 27 years old and has seen his career stalled. The second is that Danks has a lot of problems making contact with his low average and high strikeouts despite spending four seasons in Charlotte. The third thing is that Sierra has more power. Power that's developed as he's gotten older, and might develop even more as he's only 25 years old.

Speaking strictly about offensive potential, to me it looks like Sierra has more of it.

Everything else isn't equal, though. Danks might be the better overall player. In fact, because Danks' glove gives him a higher floor as a player, I'd bet on him being the more likely of the two to be with the Sox two years from now. Not as a starter, but as that fifth outfielder.

At the same time, Adam Eaton will be back, and the job in center is his. With Avisail Garcia out for the season, the Sox have more time to devote to player development. Particularly in the corner outfield spots, where Danks' glove has less value and where teams want more offense. And while nobody loves Alejandro De Aza's defense, he's good enough to be the primary backup in center, where Leury Garcia can also presumably play. These are probably the best back-of-the-roster choices the Sox can make with Paul Konerko taking up a mostly ceremonial spot.

Sending Sierra away means throwing him back on the waiver wire, which the Sox are understandably reluctant to do given their organizational lack of depth in the outfield. So for now Sierra gets his turn to audition, and Danks will go back to Charlotte where he'll probably have to hit better than Sierra does in Chicago to merit a callback without a trade or another injury opening that door for him.

Unless something better comes along than either Sierra or Danks.
