Lopez WPA year-by-year (anything positive is above average):
1.12, 0.32, -0.07, 0.78, 0.10 and currently 3rd in the bullpen at 0.22.
Riske: -0.14, 2.67, .08, -.05, -.21, .13, .31 so far this year.
Riske total last 3 seasons (i.e., since the year of the trade) : 0.23.
Lopez total: 1.10.
Perhaps your response ought to be directed at the person who thinks a Javier Lopez clone can be easily acquired "on the cheap." I was simply stating that it cost more than "on the cheap" to acquire him, and probably would again in this market.
That said, one must ask oneself, if the Sox could trade Lopez for Riske right now, would you pull the trigger?
Incidentally, most of Lopez's recent run of 1.10 WPA that you cite since the trade comes from his 16.2 inning 2006 that generated the 0.78 cited above. I don't know all the intricacies of the metric, but it seems like that number describes a good little run that Lopez had when first arrived, when he was getting both lefties and righties out effectively back then in 06, as opposed to more recently in 07, when he has been used as a LOOGY and has actually been less effective against lefties.
