Park Factors
Last Updated: 11:13 PM
There's a wide variety of park conditions on Saturday with temperatures ranging from 60s to 90s. Some of the top run-producing venues in MLB are rated at the top of the slate including Coors Field and Sutter Health Park, both of which will get temperatures close to 90° at start time. The hit-friendly Fenway Park is the next best offensive environment, although it isn't getting much help from the weather as it will be in the low 70s in Boston with light wind blowing in from right.
High air pressure is a theme on Saturday as most venues will have particularly high readings for the second day in a row. Similar to low temperatures, higher pressure is worse for offense as it reduces fly ball distance. This is indicated by the red Ps in the table below.
The Braves and Reds will play in the infield at Bristol Motor Speedway this evening. There's never been a game played in the middle of a racetrack before, and the park factor for this pop-up venue is uncertain to say the least. But Bristol, TN is located at about 1,700 feet above sea level, which would make it the highest altitude in MLB outside of Coors Field. To be clear, it isn't close to the 5,200 feet in Denver, but it's higher than the 1,000 feet at Chase Field which does get a boost in fly ball distance. Since the field dimensions are fairly standard, a modest, positive home run factor is being assigned to the venue. It will be around 70° in Bristol this evening with light wind blowing out to center field.
Some of the most pitcher-friendly weather is in Chicago this afternoon where the high pressure is accompanied by cool temps in the 70s and moderate wind blowing in from center. Although it's only single-digit speeds, the direction matters at Wrigley which is the most wind-receptive venue in MLB. Progressive Field in Cleveland will get similar conditions with wind blowing a bit harder in the face of hitters at 12 mph.

Played 4,000 feet higher in altitude than the next closest MLB park. Has an extra-large outfield to accommodate much farther carry distances. Excellent for batter contact as the high altitude limits pitch effectiveness. | +0.68 | +1.01 | +1.50 | +3.16 | |||||

Similarly, the 18-foot-tall fence in center offsets the close distance to home plate. While the tall fences help neutralize homers, they are excellent targets for singles and doubles. | -0.26 | +0.72 | +1.03 | +0.99 | |||||

The highest altitude for an MLB field outside of Coors. The right side is a bit shallower than the left. A taller 12-foot fence protects the slightly-closer-than-average center field. | +0.18 | -0.21 | -0.25 | -0.13 | ||||||

LoanDepot Park 4:10 | -10% | +4% | -2% | -3% | Roof Closed | Roof Closed | Large | 15 | +0 | Good | Avg | A retractable-roof field that is normally enclosed. The tall fences and large outfield promote doubles while suppressing home runs. | -0.23 | +0.15 | -0.19 | -0.30 | ||||||||||||

Out-blowing wind tends to correlate with warmer temperatures, and vice versa. The Corners are very deep and guarded by 16-foot-tall-fences. An extremely shallow porch in left-center makes for a cheap home run target. | -0.76 | -0.28 | +0.16 | -1.52 | |||||
