Miller (abdomen) took swings, fielded grounders and also did some running Wednesday, Marc Topkin of the Tampa Bay Times reports.
It was another step in the right direction for the rehabbing infielder, who'd taken some grounders on Tuesday as well. Despite what appears to be fairly rapid progress, there's been no update on yesterday's report that Miller is unlikely to be reinstated from the disabled list on Friday, the first day he is eligible for return.
