The Physics of a Max Muncy "Muneshot"
A true postseason moonshot differs fundamentally from a low-angle laser. Batted balls with high launch angles (34° to 40°) rely on high backspin rates (2,400+ RPM) to generate Magnus force lift ($F_m$). This counteracts gravity and keeps the ball suspended aloft, creating the iconic towering trajectory that hovers before descending into the right-field pavilion.
Lift: F_m = 0.5 · ρ · v² · A · C_L Drag: F_d = 0.5 · ρ · v² · A · C_DWhy October Air Reduces Moonshot Distance
As ambient temperatures plunge from 85°F summer heat to 55°F October night games, air density ($\rho$) surges by ~5.7%. Denser air creates higher aerodynamic drag ($F_d$), robbing well-hit balls of 8 to 15 feet of distance compared to July. Overcoming this "October heavy air" requires elite exit velocity ($105+$ mph) to clear the wall.

Expected Home Run (xHR) measures whether an identical trajectory would clear the fence in each of Major League Baseball's 30 ballparks. For instance, a 318 ft fly ball to right-field is an easy flyout in Dodger Stadium (330 ft fence), but a home run over the Yankee Stadium 314 ft short porch.

Coors Field sits at 5,280 ft above sea level where atmospheric pressure is 83 kPa, reducing aerodynamic drag by ~18% and adding 25-30 ft of carry. Conversely, Oracle Park in San Francisco experiences cold marine layer air blowing in from McCovey Cove, turning potential home runs into warning track outs.
