Rangers option Martinez to Triple-A, purchase Faulkner's contract

For the second time in less than a month, the Texas Rangers have optioned right-hander Nick Martinez to Triple-A.

Martinez will head to Triple-A Round Rock after the Rangers purchased the contract of left-hander Andrew Faulkner.

In a corresponding move, the Rangers also designated left-hander Chris Rearick for assignment.

Martinez was recalled Thursday but didn't make an appearance in Thursday night's win.

He is 7-7 with a 4.09 ERA in 21 starts.
