Martinez is a candidate to start Tuesday's game against the A's, the Dallas Morning News' Evan Grant reports.
Texas is essentially desperate to give the ball to anyone other than Kyle Lohse, although Martinez doesn't represent much of an upgrade. He is coming off an excellent start for Triple-A Round Rock, where he struck out eight and allowed one run over eight innings, but his 6.45 ERA and 7.1-percent strikeout rate in the big leagues this year illustrates his inability to get major league hitters out. If he does start Tuesday, he'll likely be sent back to Round Rock in short order.
