Baseball For Breakfast; PCL Park Factors

Good morning! Are you aready for some baseball? I hope so. Tacoma plays at Colorado Springs today in a 10:05 am game (Pacific time). Chris Seddon starts for Tacoma, the veteran Tim Redding for the Sky Sox. Hear it on 850 AM or streaming at www.tacomarainiers.com.

Yesterday the Rainiers played their third straight game that was decided in the final inning. This time the Sky Sox won it, 6-5, in the 10th. Jonathan Herrera had the bases-loaded, two-out, full count infield single to score the winning run. This was after each team scored with two outs in the ninth, sending it to extra innings. The TNT game story is here.

The game featured five home runs – no surprise in the thin air of Colorado Springs. Securtiy Service Field is one of the highest scoring environments in Triple-A baseball.

With that in mind, here are the park factors over the past theree years for the 16 Pacific Coast League stadiums.

Pacific Coast League Park Factors, 2007-2009

Parks are ranked from most offensive to least offensive. The first number is the average park factor from 2007 to 2009. In parenthesis is the year-by-year data, in the order of (2009, 2008, 2007).

Park factor is a simple percentage figure based upon the league average. Over the past three years, two teams playing at Security Service Field in Colorado Springs scored 12% more runs than two teams playing in an average PCL ballpark. And on the other side, teams playing at Zephyr Field in New Orleans score 8% fewer runs than they would in a league average stadium.

Special thanks to Dan Szymborski at Baseball Think Factory for compiling the data, and thanks to Dave Cameron (USS Mariner/Fangraphs/Wall Street Journal/ESPN.com) for helping me understand how to read it.
