See what I did there?
Let's break down where the Nats stand right now. At the plate, Ryan Zimmerman is out, likely for the remainder of the year. Zimmerman is a .285 bat with 25 HR power and ok patience. Unsurprisingly, the Nats don't have a replacement for that. Currently Ryan's injury would likely force Danny Espinosa (.217 / .283 / .347 - but with a .295 / .375 / .474 line against lefties and plays great defense) to play everyday, or perhaps platoon in some manner with Zack Walters (he of 16 Ks in 43 PAs, but lots of pop). That's not a terrible fix but it is likely a weak spot in the lineup, in comparison to what they did have.
One weak spot in the lineup the Nats can cover. There isn't a bad bat in the bunch, (yes - even Span. I'd expect him to slump but he's on average a mediocre bat, not bad) and there are several guys who can carry a team when hot. However, there isn't a true superstar guy who can carry a team when not hot, and that puts the Nats in a position where one more injury would likely put a serious hurt on this lineup. The weak spot would become a weak inning. Werth, an injury risk coming in, has been balky recently. Span, Ramos, Bryce, and LaRoche have all missed significant time this year. (Did you know Espy was 5th on the team for games played?). It seems prudent to get another bat in here now, even if there isn't a need to solve problem staring them in the face. A 2B would be the obvious solution, but just a good bench bat would do.
In the pen, the Nats don't really need anything but there is a strong desire to add a lefty who can also get righties out to the relief core. As we discussed yesterday Blevins has devolved into a LOOGY this year and that really limits his usefulness. When used as he should be now, he's a 1-2 batter pitcher, and forces the team into more 2 pitcher innings than they'd like.
There you go - that's where the Nats stand right now. Of course they could use a great bat or arm in any place, but since they don't NEED them, I don't see them making a move for them.
Now will they make a move? As we discussed earlier, Rizzo is apparently never all-in. He's not planning on making deals he feels he might lose big-time in the long term. (not that it can't happen - like if Alex Meyer ends up being Steve Carlton, just that it isn't a very likely scenario). He's looking for value in the deal meaning he's not giving up more than he thinks he's getting back. Also the Lerners have said they are "beyond topped out" which means adding big salary is unlikely. Those two things combined make trading a lot harder.
We've heard some names bandied about (Murphy, Cabrera) but honestly I think it makes a deal for a 2B nigh-impossible as good ones of those will likely be costly in either prospects or salary (or both). If the Nats are kicking the tires on these guys it's likely to see if they can get that deal. No harm in asking really if say the Rangers would trade Beltre for Sammy Solis and Tony Renda.
I'd expect a deal for a relief arm. I'd expect Andrew Miller to end up on the Nats. Probably for an outfielder. That's my guess.
