Just A Bit of Home

Since 1964, when Shea Stadium opened, the Mets have had an overall winning percentage at home of .519, 24th among the 30 franchises during that period (for franchises younger than the Mets, I just use their entire franchise history to rank them), and way below the total .538 percentage in home games that all major league teams combined have averaged since 1964.

But over the same period the Mets, since 1964 have been just slightly below average when they play as the visiting team. In away games since 1964 the Mets have had a winning percentage of .456, 18th among the 30 teams in the majors but in a virtual tie for 16th (the Mets, Phils and Tigers all have exactly 1,594 road wins since 1964, the Tigers have one fewer road loss than the Mets in that period and the Phillies three fewer road losses).

What these numbers add up to is that the Mets since 1964 have had one of the very weakest home field advantages in the majors. With a .063 difference between home winning percentage and road winning percentage, the Mets find themselves ahead of only three of the 30 franchises in strength of home field since 1964. Only the Braves, Reds and Orioles have had less of a gap between their home and road records since 1964. The average gap for all teams is .076, so the Mets' gap of .063 is quite low. The Rockies have the largest home vs road gap by far, at .155. Baltimore has the lowest gap at .041.

The Orioles are, along with the Yankees, one of only two franchises to have a road record over .500 since 1964 . But unlike the Yankees, who also have the best home record since 1964, the O's have had a home record that is only a bit above average.
