Park Factors

There's a variety of weather conditions on Tuesday with temperatures ranging from 60s to 90s. Low air pressure and high humidity are themes across much of the slate - two factors which improve fly ball distance.

Sutter Health Park is back in action this week for Astros / Athletics. The minor league venue has been one of MLB's top parks for home runs this season due largely to how receptive it is to the usual out-blowing wind. Although it will be in the mid-90s in Sacramento this evening, there won't be much wind, making it not quite as appealing for homers as it normally is.

Some of the more home-run-friendly parks are back on the schedule Tuesday including Great American Ball Park where the low air pressure will be paired with 80° at start time. The small outfield at GABP has made it perhaps MLB's top venue for home runs over its 23-year existence. It hasn't played as friendly for dingers this season and is allowing fewer home runs than expected given the fly balls hit this season. GABP is still rated positive for home runs on Tuesday.

Some of the most impactful wind on the slate is in Philadelphia and Chicago. Both parks are receptive to wind (particularly Wrigley Field) and figure to impact the game despite single-digit speeds. It will blow out to right-center at Citizens Bank and in from left at Wrigley.

Oracle Park gets its usual forecast of 60° with wind blowing out. As noted here throughout the season, the forecast calls for out-blowing wind more than 98% of the time at Oracle, but that direction doesn't translate to the field as expected. Oracle has the 2nd fewest home runs this season (1.79 per game), which is in line with where it's been historically.
