For the Reds, Austin Hays might be activated from the 10-day IL for this game. Terry Francona was hopeful he'd be ready to go by the series opener. Alexis Diaz might also be activated tonight.

Mariners vs. Reds Expert Predictions
The pitching matchup in this one is a good one. Luis Castillo has the better track record and has been quite good this year, but Nick Lodolo is enjoying an even better season. Runs might be hard to come by.
The Mariners have a lackluster offense, and the Reds, while not being that great, are better in that category. The lineup advantage tilts to the Reds, which could be the difference.
