Back from vacation day so no time for my usual nighttime routine of drafting up a post. So another 5 minute blast of thoughts.
Moving Desmond up in the lineup probably wasn't warranted by a "swinging the bat well the past couple of weeks" (really he swung it well last week and is not so hot this one AND Bernadina basically followed the same pattern) but Bernadina is terrible (.190 / .227 /.238) vs lefties this year so even a bad Desmond is going to be better than that.
I have zero faith Wang will pitch well in the majors. Well... I guess it depends on what you mean by "well". I think at best the Nats will get a 4.25-4.50 ERA guy out of it. That has some value but Wang rides the same "no-strikeout, have to do everything else right" train as John Lannan. That's ok for a lefty at 26 with some minor injury history. It's not ok for a 31-year old righty just coming back from major surgery. I think he's far more likely to get tweaked and that's all that's needed to make him worthless again.
Honestly I don't see what the endgame here is for the Nats. No one will trade for a guy with basically 1-2 starts under his belt in the past 3 years and who is a FA at year's end as part of a run for the playoffs. Pitching Wang is eating up innings better used by a prospect, like Milone or Peacock. It seems to me more of an effort to get some value from the sunk cost of paying for Wang's rehab for 2 seasons.
Take a good long look at Todd Coffey because if he's in a Nats uniform in August I'll be shocked. But don't expect anything great in return. Teams are showing interest in him in part because he's good but also because he should be cheap. A Shairon Martis (Mike Stanton trade #2) would be a high-end return.
