Mahle left Saturday's game against the White Sox with right shoulder inflammation, Do-Hyoung Park of MLB.com reports.
Mahle was expected to face a limited workload in his return from the injured list, but he ended up throwing only two innings and 37 pitches. We now know it's because the shoulder is still barking, and it could very well land him right back on the IL, though Mahle should be considered day-to-day and questionable for his next start until the Twins update his status further.
