Going back to the 1960s, Ubaldo Jimenez is one of only seven pitchers to allow two or fewer runs in at least his first 10 starts of the season. Here are the seven:

Edinson Volquez
Barry Moore
Ubaldo Jimenez
Zack Greinke
Jake Peavy
Bob Tewksbury
Juan Marichal

Here is where I found this. I had forgotten how dominant Volquez was in 2008.
