There are dozens of Anthony Swarzak-level pitchers to pick up at any given time, so the worry about not having enough pitchers around is not warranted (just look at how many pitchers the Twins signed this offseason). Maybe he has the advantage of being a known commodity. The Twins know that he really isn't very good, but is adequate in eating innings that don't matter? Even if Manship and Waldrop are only marginally better, marginally better is still better. One might think that holding Manship and Waldrop back in Rochester wouldn't do them any good at this point, and, in fact, it might cause more harm than anything else. I generally am in favor of recycling replacement level players for younger ones, who might have upside still. That idea doesn't apply in this case where all three are roughly the same age, but sometimes you can add my subtracting (if anyone actually would claim Swarzak off waivers, which is debatable). If Manship and Waldrop are kept in Rochester they may get more high-leverage innings that Oliveros, Gutierrez, Burnett, Guerra and other actual prospects would have gotten otherwise. All because of the almighty out-of-options with regard to easily replaceable players. Where's Gleeman when I need him!?
