Ryan Gusto yielded three runs in three-plus innings Thursday against the Rockies.

Gusto came out after plunking Kyle Karros to start the fourth. He still hasn’t completed five innings in any of his six starts, and his ERA is sitting at 5.55. The Marlins might activate Janson Junk to replace him in the rotation next week. Braxton Garrett also seems like an option after throwing eight scoreless innings Wednesday for Triple-A Jacksonville.
