The Cubs are expected to call up outfielder Ryan Sweeney from Triple-A Iowa and option Dave Sappelt to the Minor Leagues on Monday.
This is an interesting move. On one hand, Sweeney is almost certainly the better baseball player at this point. Sappelt just hasn't really made an impact at the major league level, for one reason or another. Additionally, this allows Sappelt to play every day, which might actually help him in the long run (I care less about Sweeney playing every day; his development is just about over). The interesting wrinkle, though, is that Sweeney and DeJesus are both left-handed (Sappelt is a rightie). Sveum has aggressively platoon players this season and it's worked well for DeJesus hiding from lefties. That's no longer on option (though Sappelt was floundering against lefties worse than DeJesus likely would've).
The upshot is that DeJesus will probably see a significantly higher number of left-handers than he was before, and slightly less righthanders. Sweeney is more of an "every 4th or 5th start, first PH off the bench" type. In that role, he could have some real value. He could also draw the occasional relief start in the corners.
Sappelt had options, so we don't lose him. He's 26, so he's not young anymore, but I think he's still got the talent level of a solid 4th OF. Sweeney already is one.
It's worth thinking about who on the 40-man roster is expendable (and the 25-man, too). I can easily eliminate 3 pitchers (Camp, Loe, Rusin) and not lose anything (I'm not sure any of the three would even be claimed), and you can throw in Rondon if you like. The only other 2 guys I could easily lose are Ian Stewart and Julio Borbon. Stewart is broken, and Borbon is replacement-level incarnate, maybe a hair above. At least three of those sports will need to be filled when Vizcaino, Baker, and Clevenger return.
