Speaking of shutouts, I looked into the shutouts this season (for no particular reason) and here's what I found.
Adam Wainwright: Rockies and Brewers
Justin Masterson: NYY and White Sox
Bartolo Colon: Red Sox (7 innings) and White Sox
Jeremy Guthrie: White Sox
Jeff Samardzija: White Sox
Anibal Sanchez: Twins
Shelby Miller: Rockies
Hiroki Kuroda: Baltimore
Jason Vargas: Baltimore
Jordan Zimmerman: Cincinnati
Jake Westbrook: Cincinnati
Brandon McCarthy: Miami
Cliff Lee: Miami
Chris Sale: Angels
Hyun-Jin Ryu: Angels
Jon Lester: Toronto
Clayton Kershaw: Giants
Kyle Kendrick: Mets
Aaron Harang: Padres
Other than the fact that the White Sox offense is prone to sucking donkey balls (evidenced by low runs and minimal walks) I'm surprised that Houston, Seattle, Dodgers, Rays (based on recent no-hit history), and the Cubs aren't listed yet teams like Cincinnati, Baltimore, NYY, BOS, TOR and teams in band boxes like the White Sox and Rockies are listed.
Also, in my research I found that a s*** load of these were 1 hit shutouts.
