This is what makes baseball so fun....so many games so lots of data to breakdown.
On the Vargas Home / Away splits...
At home: (4.53 ERA) Cleveland 2, Detroit 2, Texas, Minnesota, Oakland, Tampa, Toronto, Angels, Seattle, SF, St. Louis, White Sox, Colorado, Boston
Road: (2.73 ERA) Cleveland 2, Detroit 3, Texas, Minnesota 3, Oakland, Tampa, Toronto, Angels, Seattle
So probably a little easier road team opponent with the Twins 2 more times...but it's pretty close. Which when I put this together I was thinking his road opponents may have been way more pud hence the better record and ERA.
