For him, it works. I don't think every hitter is the same. I don't believe you can just plug a guy into an equation and say it would work out. I think Xander would benefit at being more aggressive. For Pedey, it kinda works? His best season was in 2008 when he swang at 15%. The following year, he went down to 7% and never hit 15% gain until last year. His other great season, 2011, was the highest % from 09-14.
