<\/strong><\/span><\/p>\n<p>Thanks to an update at Retrosheet.org, data for our 1925 and 1936 seasons have been updated to reflect more accurate splits. \u00a0(Note: sometimes bat hand is unknown for switch-hitters and for some other batters).Also, thanks to Ron Selter, numerous configuration data updates for 1890-1919 &#8220;Park Configurations&#8221; have been added.<\/p>\n<p>The field &#8220;Foul&#8221; in the Park Configuration now includes foul territory size (per thousand square feet) for selected parks&#8212;mostly active ones.\u00a0 Most older parks still have a letter code (L=Large, N=Normal, S=Small).<\/p>\n<p>Finally, the EXACT locations of all parks ever used in MLB games are now listed\u00a0and can be\u00a0seen by\u00a0clicking MAPS, except for two parks:<br clear=\"none\" \/> Monumental Park &#8211; Baltimore, MD<br clear=\"none\" \/> Ludlow Park &#8211; Ludlow, KY<\/p>\n<p style=\"text-align: center;\"><span style=\"text-decoration: underline;\"><strong>NOTE ABOUT PARK FACTORS<\/strong><\/span><\/p>\n<p>As a reminder, we provide two sets of Park Factor calculations: 1-year factors and 3-year factors.<\/p>\n<p>The 1-year factors are\u00a0observed factors, based on only the season in question. \u00a0While we do use an &#8220;other parks corrector&#8221; as described in the <a href=\"http:\/\/www.seamheads.com\/ballparks\/about.php\" target=\"_blank\">detail documentation<\/a>, these are essentially the factors that were observed for that particular year, so a 120 doubles factor for LH batters in Fenway Park means that left-handed batters hit 20% more doubles at Fenway than LH batters for those same teams\u2019 batters hit in games away from Fenway.<\/p>\n<p>The 3-year factors are attempts at calculating \u201ctruer\u201d factors. \u00a0There are many, many ways we could have constructed our formula, and it\u2019s difficult to determine what the \u201cbest\u201d way is, but we believe our way is at least a good and defensible way.\u00a0 Our basic formula is to use the 1-year factors for the season in question, the season immediately preceding, the season immediately following, and then the\u00a0park\u2019s long-term historical factor, all weighted equally.<\/p>\n<p>As some parks have rather long histories, while other may have life for only a few seasons, this is not a perfect method, but we believe it retains a basic simplicity while providing for a high degree of accuracy in estimating a park\u2019s impact on offensive events.<\/p>\n<p>We welcome any feedback on any of the data or suggestions for improvement, so try it out and enjoy!<\/p>\n<p><a href=\"http:\/\/www.seamheads.com\/ballparks\/index.php\">http:\/\/www.seamheads.com\/ballparks\/index.php<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We at Seamheads.com are proud to announce another new update of the Seamheads.com MLB Ballparks Database, created by Seamheads.com co-founder Kevin Johnson and designed for the Internet by Dan Hirsch, fellow Seamhead and founder of TheBaseballGauge.com.\u00a0 And this year&#8217;s version includes fantastic new data!
