Duffy (back) is not in the lineup for Saturday's game against the Marlins, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Duffy was a late scratch Friday after experiencing back spasms on his way to the game, and it's unsurprising for the Rays to exercise some caution coming out of the All-Star break. It's unclear if 27-year-old will be available off the bench and he should continue to be considered day-to-day. Daniel Robertson will start at third base and bat second for Tampa Bay.
