Unable to warm up bullpen/retire pitcher

[zo0tie831_XBL]

Im a newer the show player so this may be a dumb question but how do i change my pitcher in rtts? The bullpen option won’t show up in pause menu or quick menu doesn’t pop up wheni hit down on the dpad. My pitcher just keeps getting tired af and manager ends up pulling my pitcher out in the 8th all the time so i know that ain’t too good. TIA

It's done by the manager, not the player. If you don't want to play the rest of the game you'll need to simulate and exit.
