Cards pitchers celebrate John Gast's walk with 'good eye' finger goggles

On Tuesday night, the other four members of the Cardinals rotation found a nifty way to congratulate John Gast for drawing a walk: the international symbol for "good eye." We're hoping this becomes a regular thing, much like the "three goggles" following a successful three-point shot in basketball.

Extra credit to Adam Wainwright for successfully executing the varsity-level upside-down version.
