Clevinger was optioned to Triple-A Columbus on Wednesday, Jordan Bastian of MLB.com reports.
The Indians don't need a fifth starter until June 17 due to multiple off days and Clevinger wasn't exactly sharp in his last outing, allowing five earned runs over four innings in a blowout loss to Colorado. The right-hander will head back down to Triple-A, where he posted a 1.50 ERA over six starts before getting the call to the big leagues. Expect Clevinger to be back in the Indians' starting rotation when a fifth starter becomes necessary, as their options are rather limited in that regard.
