The Washington Nationals are making good on their rebuild, playing more competitive ball while developing their young talent. But they still have more work to do, which will make them sellers at the trade deadline.

The MLB trade deadline is July 30 and the Nationals are only a few games back of a Wild Card spot. As promising as that is, they are still not a World Series contender. It would benefit them a lot to ship off the veteran talent that won’t be there when they contend for the postseason again. Indeed, the Nationals have a bunch of veterans they could look to trade, according to Jim Bowden of The Athletic.

Bowden writes the following: “The Nationals are holding off on calling up some of their top prospects because they’re hoping to deal several veteran players such as Lane Thomas, Eddie Rosario, Nick Senzel, Joey Gallo, Jesse Winker and Joey Meneses with the idea that if they can, it will allow them to promote prospects in August and September.”

The Nationals can send out their plethora of experienced hitters, though not all of them are bound to command a big-time trade market. Some of them, though, could be hot commodities.

Winker, in particular, has rebuilt some of his value with the Nats. The former All-Star's OPS of .771 is his best in two seasons and he remains elite at drawing walks. Any team in need of a left-handed hitting outfielder will be sure to call about him.

Senzel is in the best season of his career, posting career-highs in on-base percentage (.356), slugging percentage (.435) and walk rate (14.6). His home-run percentage of 3.7 is the second-highest, trailing just last season at 3.9. He has one more year of team control, too.

Thomas, meanwhile, had more value last season when he was hitting much better. His strikeout rate is down and his walk rate is up, though, so he could have a big second half. He's also still a prolific base stealer, one of just nine hitters this season with 15 stolen bases and a success rate of 80 percent.

Gallo, Rosario and Meneses are all not having great seasons. They may be very cheap to obtain but may also not have any takers. Washington could move on from Gallo and Rosario easily but will probably opt to keep Meneses since he has several more years of team control.

The Nationals have players like CJ Abrams, MacKenzie Gore, Luis Garcia Jr., Keibert Ruiz and Jake Irvin playing in the majors as they enter their primes. They also have a bunch of top prospects who they plan to call up, namely outfielders James Wood and Dylan Crews, who are fourth and sixth respectively on MLB.com's list of top 100 prospects. They could even look to call up infielders Brady House (ranked 36th) and Yohandy Morales (ranked 88th).

Washington has been in sell mode for quite some time now but is starting to put the pieces together for its next great roster.
