Park factor history
Five single seasons and the three year rolling view Baseball Savant shows by default. Reading them side by side is how you tell a park that has changed from a park that had one odd year.
| Season | wOBA | Runs | HR | SO | 2B | 3B | BB |
|---|---|---|---|---|---|---|---|
| 2026 | 99 | 98 | 109 | 112 | 97 | 119 | 105 |

| Three year rolling | 100 | 100 | 111 | 107 | 96 | 84 | 101 |
The ballpark itself
Elevation is 45 feet, close to the 518 foot league average, so altitude is not doing anything here. Home plate points north northwest toward centre field, at 343.0 degrees, which is what turns a wind forecast into a blowing out or blowing in read rather than a guess. The roof is listed as retractable in the MLB venue record, so the run environment changes with the roof call. Playing surface is grass. The average fence sits 364 feet from the plate, 7 feet shallower than the league average, and the average wall is 12.6 feet high.
| Location | Distance | vs league | Wall | vs league |
|---|---|---|---|---|
| Left field line | 315 ft | -16 | 18.2 ft | +8.3 |
| Left centre gap | 367 ft | -12 | 24.2 ft | +14.3 |
| Centre field | 409 ft | +7 | 9.4 ft | +0.7 |
| Right centre gap | 378 ft | -2 | 9.6 ft | +0.5 |
| Right field line | 325 ft | -1 | 6.3 ft | -4.8 |

What it means for a bet
Totals
Close to neutral on runs, which makes this a park where the pitching matchup and the weather carry the total rather than the venue.
Home run props
Home runs outrun overall scoring here by 11 index points. That is the signature of a park that gives up damage in bursts: quiet innings and then a three run swing. Home run props and team total overs read better than the game total.
Strikeout props
A strikeout index of 107 means the park is quietly adding Ks. A starter arriving from a contact friendly park is usually priced on his season line, not on tonight's venue.
Handedness
The home run index favours left handed hitters by 8 points (108 against 116). When a lineup is stacked the other way, the park is doing less for them than the headline number suggests.
Time of day
Day games run 12 points lower on the run index than night games (92 against 104), which is a real split and not one most totals models carry.
Roof
With the roof open the run index is 130, closed it is 100, a 30 point swing. The roof decision is public before first pitch and the total does not always move with it.
Every index on this page is a three year rolling figure unless the column says otherwise, and all of it is league relative: 100 is average, not neutral in an absolute sense. Park factors describe the venue, not tonight's pitching matchup, and they are the starting point of a number rather than the whole of it.
