By percentages, that's pulling the ball 30.3% in 2011 compared to 32.1% in 2010, going up the middle 48.5% to 55.5% and going the other way 21.2% to 12.4%. So maybe standing nearing the plate is giving him better coverage on the outside pitches and he's driving them to the opposite field.
Howard's BB% had dipped slightly this year, but his K% his a historically low 17.8 (down from 25.3 last season and 27.4 average). Perhaps another sign of better plate coverage.
One other note of interest, Howard has 2 sac flies this year compared to only 3 all of last season.
This is all based on a very small sample and Howard can be a streaky hitter, but if these results are because of his new approach, it is encouraging for Phillies fans.
