Hit Tracker Power Projection Aaron Rowand 1-year report: 2008 Projections, using 2007 data
2
Hit Tracker Power Projection Method Observation and analysis of all long fly balls (any ball hit far enough to approach or clear the outfield fence of any MLB ballpark) for specified time period (1-3 seasons) Projection of each long fly ball, via Hit Tracker, into each of the 30 MLB parks, in each park’s average weather conditions. Evaluation of each projected ball as home run, off wall or “catchable”. Evaluation of each “catchable” ball via range model as Flyout or hit. Compilation of projected results for each ballpark, via substitution of projected results for actual results, and weighted towards more recent results (e.g. 3-2-1 weighting if 3-year analysis). Compilation of projected results as member of each team via 2009 schedule The Hit Tracker Power Projection method uses detailed individual analysis of every long fly ball hit by a player, and the ability to project those fly balls into other parks and weather conditions, to create the most accurate possible projection of a player’s future hitting performance. Key Steps:

Comparison to Actual 2008 Results Aaron Rowand, 2007 Rowand’s 2008 projection was off significantly when compared to his actual full season in 2008. However, the Hit Tracker projection system cannot predict the impact of “playing hurt” (nor can any projection system, for that matter). Rowand played in 152 games in 2008, but he really played two different seasons, divided by a right quadriceps injury he sustained on June 6 th : * Prorated for full season Rowand’s performance during the first 10 weeks of the 2008 season corresponded quite well with his Hit Tracker projection for the Giants, considering the limited sample size of less than 1/3 of a season. The data suggests that Rowand’s offensive output was severely reduced by his unhealed injury, but his prospects for a return to productivity, if healthy, are promising…
