I think the knee-jerk reaction to this change has been "better trade Vargas" or "this sucks for Vargas" or "Vargas is gonna be bad now"... I'm not seeing it. The advantage Vargas gets from Safeco isn't really on dingers--someone said over on LL that if you look at the overlays, the new fences would have added zero home runs against Vargas in 2012. It's not that significant of a change. The real value boost that Vargas receives from Safeco is in the "float effect", the one that turns all the doubles and triples into deep fly ball outs. Unless changing the walls has altered the fluid dynamics of the wind in Safeco, I don't believe they're making a change to correct the wind thing. It's my general impression that this change will still allow Vargas to maintain his home/road splits and thus his value. I wouldn't sell just yet.
