Peavy, Young, Maddux is a pretty decent top 3. Chris Young is an extreme fly ball pitcher playing in Petco. He'd probably be Sean Marshall if he played at Wrigley. Almost no difference in home and road ERA career: http://www.baseball-reference.com/pi/psplit.cgi?n1=youngch03 That doesn't mean he doesn't benefit from playing half his games at Petco. Plus all of those road stats aren't at Wrigley. and the Home/Road ERA is completely ignoring the fact that more than a third of his home starts were made in arlington, not Petco. Arlington stats: 113 IP, 113 H, 4.70 ERA, 18 HR, 29 BB, 95 K Petco stats: 197 IP, 143 H, 2.97 ERA, 21 HR, 78 BB, 188 K I think it's safe to say that Petco has been pretty friendly to Chris Young.
