Koehler was optioned to Triple-A New Orleans on Tuesday.

EDGE Analysis

Koehler entered Tuesday's game against the Astros with a 5.60 ERA and exited with a 7.04 ERA. The right-handed hurler allowed eight runs on seven hits and four walks over three disastrous innings. The 30-year-old had already been treading on thin ice in the Marlins' rotation and Tuesday's performance was apparently enough to earn him a demotion to the minor leagues. He'll look to straighten things out in New Orleans with his sights set on rejoining the big-league club for the stretch run of summer.
