Having likely thrown his last pitch in a Washington Nationals jersey, starter Jordan Zimmermann is expressing his gratitude to fans of the only major-league team he's played for.

Although there's still an outside chance Zimmermann could be re-signed by the Nationals in free agency this offseason, he knows the odds are slim given the Nats' payroll situation and young arms waiting to make an impact at the major-league level.

After concluding his seventh and likely final season with the Nationals, Zimmermann shared a message with the Nats' fan base, which his agent Mark Pieper posted on Twitter:

In seven seasons with the Nats, Zimmerman posted a 70-50 record with a 3.32 ERA and 903 strikeouts in 1,094 innings pitched. In what appears as though it will be his final season with the team, the 29-year-old righty went 13-10 with a 3.66 ERA and 164 strikeouts in 201 2/3 innings in 2015.

Although Zimmermann sees the writing on the wall for his departure from D.C., his agent wouldn't rule out a return to the Nats, as he told a fan on Twitter that there is "always a chance" Zimmermann could wear the Curly "W" next year.
