The Miami Marlins have optioned Tom Koehler to Triple-A New Orleans.

Koehler, 30, has been a fixture in Miami's rotation since 2013 and hasn't thrown a pitch in the Minor Leagues since then.

The Marlins avoided arbitration with Koehler prior to the season by agreeing to a one-year, $5.75 million salary for 2017. He allowed eight runs on seven hits and four walks through just three innings on Tuesday night and has already given up 10 home runs in fewer than 40 innings this season.
