Ginn will no longer start Tuesday's game against the Rangers, as the Athletics want to give him additional rest before his next outing, Martin Gallegos of MLB.com reports.
Ginn has already logged a career-high 138.1 innings this season, so the decision to push him back could simply be about managing his workload. The right-hander is expected to make a start later this week in Seattle, though the exact date hasn't been revealed.
