Home Field Advantage

With the Red Sox having their only wins so far this year at home along with their reputation of being tooled to perform better at Fenway, I decided to take a quick look at the American League teams Home versus Away wins in the Red Sox Bill James era (2003-2010). Listed below are the differences between home wins and away wins for each team per year in the time period along with their corresponding mean and Standard Deviation.

2010 2009 2008 2007 2006 2005 2004 2003 Mean STD Tampa Bay 2 20 17 8 21 13 12 19 14.00 6.59 Boston 3 17 17 6 10 13 12 11 11.13 4.88 NYYanks 11 11 17 10 3 11 13 -1 9.38 5.71 Toronto 5 13 18 15 13 6 13 -4 9.88 7.10 Baltiore 8 14 7 1 10 -2 -2 9 5.63 5.93 Chi White Sox 2 7 19 4 8 -5 19 16 8.75 8.65 Minnesota 12 11 18 3 12 7 6 6 9.38 4.78 Cleveland 7 5 19 6 10 -7 8 8 7.00 7.13 Kansas City 9 16 1 1 6 7 8 -3 5.63 5.90 Detroit 23 16 6 2 -3 12 4 3 7.88 8.51 LA Angels 6 1 0 14 1 3 -2 13 4.50 6.02 Texans 12 9 1 19 -2 7 13 15 9.25 7.07 Oakland 6 11 11 4 5 -3 13 18 8.13 6.47 Seattle 9 5 9 10 10 9 13 7 9.00 2.33

It is no surprise that the Red Sox have a strong Home/Away Wins record (2nd),

but I was surprised that the Tampa Bay Devil Rays were even better in this

statistic. Also note how dominate the AL East is in Home Wins versus Away Wins.

Now for the Red Sox in 2011 having all your wins at home is still bad.
