the suggestion is they want someone who is fast who can run for Wieters who can then stay in and catch, rather than burn a runner and then Lobaton. I/M/O, don't carry Lobaton, but he's Gio's caddy. You also saw the Gio/Severino combo not work well yesterday.
You don't think Gio being sick had more to do with that? Boz speculated in his chat that if they'd had someone available, Gio wouldn't have pitched. Said he looked pretty pale and under the weather after the game.
