On the heels of a historic run to their first World Series championship, the Washington Nationals will remain at the center of the baseball universe with Stephen Strasburg and Anthony Rendon hitting free agency. 

Rendon figures to be the top position player available, and if he doesn't return to DC, it appears the Nationals already have their eyes on a potential replacement. 

According to's Mark Feinsand, the Nats are one of four teams showing the most interest in former AL MVP Josh Donaldson along with the Phillies, Braves and Rangers.

Rendon, Donaldson, Mike Moustakas and Todd Frazier highlight a deep free-agent class at the hot corner, and Feinsand adds that teams who miss out on Rendon or don't want to wait for him to make his decision can turn to Donaldson. 

Donaldson is coming off a one-season stint with the Braves where he posted a .259/.379/.521 slash line to go with 37 home runs and 94 RBI. Entering his age-34 season, Donaldson isn't quite playing at the MVP-level he did with the Blue Jays, but it's clear he can still produce.

If the Nationals aren't comfortable with committing long-term money but still want some production and a veteran presence at third base, Donaldson could be the perfect fit. 

The Braves signed Donaldson to a one-year, $23 million contract last November, so there's a decent chance he'll make a decision sooner rather than later.
