Miller told reporters on Tuesday that he "tweaked" his lower ab in his final at-bat in the Rays' 8-7 loss to the Indians when he ran to first. He said it is not a groin, oblique or hernia injury, but it's "in that area."
Cash said there was "concern" regarding whether Miller would need to go on the disabled list, but he added, "We don't know yet. We won't have a doctor [examine him] until [later Wednesday] or tomorrow."
Daniel Robertson started at second base for a second consecutive day on Wednesday. Cash praised the way the rookie has performed in the field while playing second base, shortstop and third base.
"Wherever we plug him, it seems like the days that he plays, he's making a really good play for us," Cash said. "... Just a lot of comfort, whether it's second, short or third."
