However, since the criteria is the same across the board, I don't think it causes any kind of a significant difference in data. Additionally, I'm unaware of any other way to filter out rookies using BBRef's Play Index. EDIT: Just got your whole point (yeah, I'm slow): if I could find a list of some sort of rookie-eligible pitchers who have started games this season, it would be very easy to calculate the percentage, but you're right -- it could be enough to get up to the percentage Cohen cited. Still, it's the lowest of the decade, so it's not the story it's being made out to be.<div class="comment-remix-meta"><a href="#" class="replyto" onclick="replyto('3698','Bill Baer'); return false;">Reply</a> - <a href="#" class="quote" onclick="quote('3698','Bill Baer','Jeff,\r\n\r\nThat\'s a really good point -- thanks for that.\r\n\r\nHowever, since the criteria is the same across the board, I don\'t think it causes any kind of a significant difference in data.

For example, I would assume your first list above does not include Josh Outman of Oakland, who pitched 25 innings in 2008. But I believe he would still be considered a rookie and therefore his 11 starts in 2009 could be considered "rookie starts."<div class="comment-remix-meta"><a href="#" class="replyto" onclick="replyto('3697','Jeff Lubbers'); return false;">Reply</a> - <a href="#" class="quote" onclick="quote('3697','Jeff Lubbers','Not sure if this would make up the entire difference but wouldn\'t a pitcher who had a cup of coffee in 2008 not show up on your list because 2009 would be the second season of his career?
