Park Factors

The warm weather remains on Saturday with 11 out of 13 outdoor games expecting 80° and higher. With many of the league's best run-producing parks left off the slate this weekend, the warm temperatures generally amount to neutral hitting expectations for most games.

Target Field gets its second day in a row of good hitting weather. It will be in the mid-80s with low air pressure and mild wind blowing out to left field for Royals / Twins.

The roof will be open in Milwaukee where American Family Field is once again rated well for home runs due in large part to the warm temperatures. The odd-shaped field in Milwaukee tends to be vulnerable to homers when it's hot out - particularly the shallow middle-third of the outfield. The wind is blowing out to left on Saturday, but that doesn't matter very much as the tall stadium walls in Milwaukee make the park fairly immune to wind.

Speaking of wind that doesn't matter, the out-blowing wind at Oracle Park is nothing new (it blows out every game). The venue was designed to neutralize wind, and the park ranks toward the bottom of the league each year in homers despite how the forecast appears for every Giants home game. It will be 60° in San Francisco this evening.

The left-field corner is particularly deep while most of the outfield perimeter is closer than average. A 21-foot-tall fence compensates for the short distance down the right field line.+0.03+0.23+1.18+1.11

-8%+5%+9%+6%High 8  8  9 88°86°84°53%1018Large596 -3AvgAvgA challenging venue for home runs with a very deep center field. The entire left side is deeper than average and the 15-foot-tall fence in right further complicates things for hitters. Batter contact is better than most parks, possibly aided by a clean batter's eye.-0.18+0.16+0.95+0.49

Straight-away center is close to home plate but extends to an extremely deep right-field gap. Cool temperatures are the norm and the ever-present out-blowing wind is neutralized by the stadium architecture.-0.46-0.10+1.06-0.18
