Every MLB ballpark ranked by its run factor, the most run-suppressing venue first. A run factor below 1.00 means the park produces fewer runs than a neutral one, and the ranking orders the staged numbers from lowest to highest: big outfields, heavy marine air and deep fences all drag the run environment down.

Pitcher-friendly means the venue drags the run environment below neutral, not that the home staff throws well. The lowest run factors belong to parks where the ball dies: sea-level air, damp marine layers, spacious outfields and foul territory that steals at-bats. The home run column shows the same suppression in slices, and the strikeout factor above 1.00 marks parks where balls in play die harmlessly and strikeouts pile up.
A low run factor does not make a pitcher great, and it does not hurt the home offense any more than the visitors: both teams bat in the same environment. The factors describe the venue only, staged as static attributes rather than a rolling snapshot.
