I can't believe people are already judging this trade. WMP has 5 at bats and everyone is giving up on him....jeez people look at David Ortiz. Minnesota did the same thing to him alot of people are doing to WMP and look Ortiz now. WMP is a kid, he needs time. But the fact is Arroyo is a #3 starter at best, WMP is potentially a All-Star cleanup hitter.
This trade may seem bad this year, next year, maybe even the year after that. But in 2,3,4 years when WMP is a All-Star outfielder nobody will be talking about this being a bad trade.
