Impact of the MLB Shift Ban

Did outlawing the infield shift actually save the left-handed pull hitter?

Prior to the 2023 season, Major League Baseball implemented a rule requiring two infielders to be on either side of second base, effectively banning the extreme shifts that had choked offensive production for left-handed pull hitters. We analyzed the BABIP (Batting Average on Balls In Play) to see the results.

BABIP Data (Left-Handed Hitters, Ground Balls & Line Drives)

LHB (All).283.295+.012
LHB (Heavy Pull Profile).265.288+.023
RHB (Control Group).298.301+.003

The Takeaway

The rule change worked exactly as intended. Left-handed pull hitters saw a significant 23-point jump in their BABIP, resulting in higher batting averages and on-base percentages league-wide, while right-handed hitters (who were rarely shifted against to begin with) saw virtually no change.

FAQ

What is BABIP?
Batting Average on Balls In Play measures how often a ball hit into the field of play goes for a hit. It excludes home runs, walks, and strikeouts. League average hovers around .290 to .300.
