10-Year Veteran Named Starting Pitching Fit for Nationals

In this story:
Paul Toboni has already started putting in some work on the Washington Nationals' roster.
After designating some players for assignment and outrighting others to Triple-A Rochester, there have been some notable departures that has freed up space on the 40-man roster. How the front office chooses to go about backfilling those openings will be interesting to see. But it's clear some major changes could be coming this winter.
One area that needs a bit of help is the starting rotation. If they decide to hold onto MacKenzie Gore, then adding a true No. 2 guy behind him would do this team wonders. And if they opt to ship out their ace, then they'll need someone established to take over that spot.
While signing someone like Dylan Cease is what everyone in this fanbase is hoping for, that doesn't seem likely. And that's why Thomas Carelli of District on Deck highlighted Zach Eflin as a realistic option the Nationals could land this winter.
"Given the Nationals payroll, they will look for a player priced much more cheaply. ... Eflin offers a moderately priced option with manageable expectations. He is a free agent and appears to command an AAV of $16 Million," he wrote.
Why Zach Eflin Would Be Good Fit With Nationals

Ideally, Eflin would be added as the No. 2 behind Gore. That would allow Josiah Gray to work back from his injury and Cade Cavalli to pitch more big league innings without the pressure of being a top-of-the-rotation arm just yet.
Eflin, a 10-year MLB veteran, has seen just about everything during his journey. He's gone from being the 33rd overall pick in the draft to being part of the return that replaced a beloved franchise legend to not living up to the hype to earning Cy Young votes and now having to produce a bounce-back season.
That is a great person to have in this young clubhouse, especially with a 33-year-old manager in place who has never even coached inside a major league dugout before. But beyond the outside factors, Eflin would also provide a major boost to this starting staff.

While he struggled this season with his performance and health, he has been one of the most consistent starters across the majors the past few years. Before the 5.93 ERA he put up across 14 starts this campaign, he had recorded an ERA+ figure that was either at or above the league average of 100 in five out of his last six seasons.
Eflin has also consistently gotten unlucky throughout his big league career. While his cumulative ERA reads 4.28, his expected ERA is down at 3.85. That trend continued this year, where his xERA was at 4.53 compared to his actual mark of 5.93.
That signals some positive regression could be coming for the veteran, and it would be wise for the Nationals to have that happen in their uniform as they look to fill out a competent starting rotation.
