Snake bites

• The D-backs have still not announced starters for their series with the Rays on Tuesday and Wednesday.

With an off-day Monday, the D-backs could decide to skip a fifth starter, or they could choose to keep Zeke Spruill in the rotation and give every pitcher an extra day of rest.

"We're not leaning towards anything at this point," Gibson said. "We just had a discussion."

The team will wait and see how Trevor Cahill looks in his rehab start Monday for Triple-A Reno, as that could play a role in the decision.

• Speaking of the rotation, Gibson generally likes to err on the side of giving his starters an extra day rather than skipping one.

"You can just see when guys get a little tired, maybe they don't come out as sharp, and it takes them a while to get going in their next game," Gibson said. "You give them an extra day, it seems to freshen them up a little bit."

• Heading into Saturday's game, Martin Prado was 19-for-53 (.358) in 14 games since the All-Star break.
