HAL PH Decisions

Playing 70's League/Mystery Card.
Own S Brye who, due to injury is either 72/.592 OPS 8L or 74/.684 OPS E. After 82 AB's, based his splits LBA-.154/RBA-.302, I assumed he's in 74/E card.
HAL PH Biittner for Brye vs. a RHP. Shouldn't that telegraph Biitner is in a better card than Brye vs. RHP'ing??

Possibly but it also depends on the pitcher splits, ballpark, and maybe clutch hitting if there were 2 outs with runnners in scoring position.
