Gallo will be the everyday 1B with Meneses as primary DH per Davey.
so it sounds like, among Rosario, Winker, Gallo, and Meneses, on any given day, 3 of the 4 will play. All 4 can play when Thomas is off, and I suppose the one on the bench will be available to pinch hit (if for Robles, then remain in the game in a Winker Rosario Thomas OF).
