The Athletics will begin a six-game homestand at Las Vegas Ballpark tonight - which has one of the most prolific run environments in the Pacific Coast League (AAA).
Vegas sits 2,000 feet above sea level, which would rank 2nd among active MLB parks. It's still 3,200' below Coors Field (#1) but 900' higher than Chase Field (#2).
It will be 90ยฐ at start time this evening with wind blowing out to center at 10-15 mph. The wind figures to be impactful given the park's open-air style.
The outfield at Las Vegas Ballpark is larger than the typical MLB standard, presumably to account for the persistent heat and high altitude - which help the ball travel farther. It measures 340' down the lines, 380' to each gap, and 415' to center. Most of the left side is guarded by a 13-foot-tall fence.
It's being assigned a substantially hitter-friendly park factor for tonight due to the high altitude, hitter-friendly weather, and its offense-heavy reputation in the PCL.
Given its lack of MLB history, park factors for this venue are far less precise than an established MLB stadium. They should be considered more of an educated guess this week than an exact science.
