直接说这篇的结论：
大联盟球队更愿意花大把作物交易投手
球团显然更在乎交易来的投手能帮你多拿几胜
数据皆有盲点，小心使用，严防战文
Pitcher is the (main) pitcher involved in the trade. Sometimes pitchers are
traded with additional pieces, and they are accounted for; very rarely is the
starting pitcher not the main piece (the Josh Beckett, Carl Crawford, and
Adrian Gonzalez trade is a rare exception).
Team is the acquiring team.
Difference is the total surplus value of the pitcher (along with the rest of
the package, if that is the case) minus the surplus value of the return
package. So the lower the number, the more surplus value given up to acquire
a pitcher.
