Why do fly balls hang so long in the air?

SDS

it is so unrealistic even when the shift is on for a left-handed batter and you hit a fly ball to left field. The left fielder literally has 5 seconds to get to the ball. What kind of data does SdS use for this nonsense?

The rare time I do use the shift the ball always seems to find that Bermudian triangle in left field
