Since 2018, the difference between the Phillies’ home and road records has been baffling:
At home, they’ve won at .590 clip (a 96-win pace over a full season), the 8th best home record in MLB.
On the road, their winning percentage has been .395 (a 64-win pace), the 24th ranked road record.
If we compare the two percentages, they have won at home 150% as often (aka 50% more) as they’ve won on the road.
We’ll multiply this by a 100 to make life a bit easier, and call it a home field advantage (HFA) of 150.
