Jimenez (shoulder) fired a scoreless two-thirds of an inning in Triple-A Las Vegas' win over Sugar Land on Sunday.
Jimenez was making his fourth rehab appearance overall and was able to bounce back from a rocky outing Thursday where he'd surrendered three earned runs over one-third of an inning. Sunday's appearance was Jimenez's first with the Aviators in which he didn't allow a run, so the Athletics would likely want to see him build up some more momentum before activating him.
