Ok, Padre Homer got me to thinking so I did a little stat work and ranked all NL stadiums by percent of HR's/AB for the visiting team. I used only visiting team numbers so that the "it's in their heads" argument that gets blamed on our Padres could be removed from the equation. To make sure to keep the comparison fair, I used the visiting teams data for all of the other stadiums also. Well gang, Petco didn't come in last place but out of 16 NL stadiums we were 13th in the fewest HR's per AB's.
Petco's percentage for the season was .0267. This was based on 2803 visitor AB's and 75 HR's. Now carrying this idea a bit further (and a hell of a lot more work) I broke out the 1st 40 games from the rest of the season. I wanted to see what influence the April, May, June and 1st week of July weather/marine layer had. We all noticed that post All-Star break showed improvement. Some attributed this to the players learning to deal with the new park and making adjustments. Some cited change in weather. Since our opponents did not have the label of head cases.........if the stats for 1st half differed from 2nd half it should be attributable to conditions other than mental. First 40 games(April, May, June 1st week July) our visitors had 1367 AB's we allowed them 28 HR's for a percentage of .0204. Next 42 games ( 2-4 week July Aug, Sept) our visitors had 1436 AB's and we allowed them 47 HR's for a percentage of .0327. If I had ranked Petco on 1st half percentage of HR's/AB (remember this is our opponents not our guys hitting) we would have been last on the list of Stadiums. If I had ranked Petco only on the 2nd half it would have been between 7th and 8th (between Minute Maid and Olympic stadium). Season totals as I mentioned rank Petco #13th
Since the Park factor data is calculated by PF=(home RS + homeRA)/(home G))/ (road RS+road RA)/(roadG)) There has been the argument that our players (RS Home vs RS Away) mental approach contributed to a lower Park Factor. I would argue that using only visitor stats eliminates this being attributed to the Padre hitters. It appears clear to me that Petco is one of the most difficult parks to go long in especially early in the season. It will be interesting to watch 05 and see if this same data holds true. Low percentage of HR's early in the season and improvement from mid July on. Either way, the early half of Petco's season sure affected the season total.
Our power hitters especially Nevin, Klesko, & Giles have been raked across the coals for voicing their concerns about Petco playing tough and suppressing long ball numbers and they were/are absolutely correct. Even with the improvement as the season progressed, season totals were lower than in all but 3 other NL stadiums. So gang, can we remove the crybaby, head case, it's all in their heads label off of our guys? That is unless you think that through some big conspiracy our guys "got" to the opposition and convinced them to lay off the long balls at Petco just so they could be proven correct in their concerns about the way Petco would play.
