They sure did. Pierre's BABIP was around .250 for the first few months of the season, and climbed up over .300 in the 2nd half. His career BABIP is .320, but was only .305 last year. The league average is somewhere around .300. As for the general discussion, BABIP is Batting Average on Balls in Play, so it doesn't take into account home runs or strikeouts. Thus, its calculated by (Hits - HR)/(ABs - HRs - K). There are a few things to consider when looking at BABIP: 1) a pitcher doesn't have much control over the % line drives given up, but can control the % of ground balls and fly balls given up. Changing a pitcher's GB/FB ratio will change both his BABIP and his average, OBP, and slugging rates against. 2) a hitter's BABIP doesn't vary much from season to season. A hitter can control the line drive % (ala Jeter), and can also control his BABIP through excellent bat handling (ala Ichiro) or speed (ala Pierre). However, usually a hitter won't improve dramatically in these abilities with time. 3) an anomolous BABIP is usually a sign that the extra hits on balls in play was due to good fortune (or bad fortune or team fielding, for BABIP against). Players tend to not change their abilities with regards to BABIP, just their luck. A hitter with an anomolously high BABIP one season can be expected to have a BABIP closer to their career norm the following year. Likewise for BABIP against with a pitcher. This is all relavent because of Mark DeRosa. His BABIP in 2006 was well above his career average. His BABIP bump comes from an increase in line drive %. If that represents a change in his ability to hit line drives, then we can expect him to produce at or near his 2006 level. If the extra live drive % is a result of friendly scoring of those few lucky hits that found holes (a soft liner to the OF that falls is more likely to be called a line drive than one that is caught), then his production will likely return to his pre-2006 level. Its hard to say what caused his increased LD% in 2006. Only time will tell, i suppose... (OT aside: Derwood, you realize that if OSU and Michigan win their bowl games, and ND and Wisconsin win out, then PSU will have 4 losses, all to teams that will likely end the season in the top 5? I'm a HUGE PSU fan, and think a big win Saturday and a win in the Outback bowl would make this a successful season.)
