The Louis Varland 9th-Inning Breakdown

When a grounder pulls the 1st baseman deep toward the hole, the pitcher must break instantaneously, sprint 85+ feet on a banana-curve path, establish bag footwork, and receive an off-balance throw while tracking a charging runner. At 320 ms reaction delay with high late-game pressure, the combined catch completion plummets to 45%, yielding a +18.4% win probability surge for Detroit.
