Martinez (1-3) allowed five runs on six hits and a walk with two strikeouts over four innings in a loss Tuesday to the Athletics.
Martinez was called up to make this start as a replacement for the ineffective Kyle Lohse, but Martinez didn't fare much better. He allowed three home runs and managed just three strikeouts as he wasn't fooling anybody. Martinez allowed four home runs in the three starts prior to his demotion, and with no sign that he's fixed the problem, his stay in the Rangers' rotation could be a short one.
