First Pitch: 6:40 PM MST / 9:40 PM ET / 6:40 PM PT
Venue: Chase Field, Phoenix, Arizona (Retractable Roof)
Venue & Weather Conditions
Chase Field is one of MLB’s most controlled environments thanks to its retractable roof. Early June in Phoenix almost always means the roof stays closed.
Forecast
Temperature (outside): 101–104°F
Humidity: ~18%
Wind: 6–10 mph from the southwest
Rain: 0%
Roof Status: Roof expected to be closed
Impact: Closed roof = neutral-to-slightly hitter-friendly environment. Ball carries well to left-center, and right-handed power gets a boost.
