• Williams has had at least four players volunteer to serve as an emergency third catcher. Two of those, Bryce Harper and Jayson Werth, are former catchers, but Williams isn't planning to let them anywhere near the plate. Two others, Danny Espinosa and Tyler Moore, are more realistic options in a worst-case scenario.
• As for another emergency situation, Williams said that under the right circumstances, he would consider using a position player to pitch. That's something his predecessor, Davey Johnson, never did.
"If the game's completely out of reach and we're taxed in our bullpen, there may be a need for that," Williams said. "And again, we look at winning today's game, but if there's simply no chance we can win today's game, I don't want to cost us tomorrow's game, too."
