Brad Penny on Saturday became the 13th pitcher to make at least one start this season for the Marlins, breaking a single-season team mark for number of starters used.

“We’ve used a lot of guys,” manager Mike Redmond acknowledged.

The season-ending injury to Jose Fernandez in May has been a significant factor in the high number of starters. Three of them — Anthony DeSclafani, Randy Wolf and Andrew Heaney — were each trotted out one after another in an unsuccessful attempt to fill Fernandez’s spot in the rotation.

While Nathan Eovaldi, Henderson Alvarez and Tom Koehler have managed to make all — or nearly all — of their scheduled starts, the other two rotation spots have been a revolving door.

Kevin Slowey, Brad Hand, Jacob Turner, Jarred Cosart and Brian Flynn have also started for the Marlins.
