It’s official: according to Ryan Lawrence, Cole Hamels will start the Grapefruit League opener against the Houston Astros this Saturday, with speculation running rampant that Hamels will also be pegged the Opening Day starter. Pitching coach Rich Dubee believes he will use Hamels, Roy Halladay, and Cliff Lee in the opening series against Atlanta, with a preference to splitting his lefties according to Matt Gelb. In addition, Gelb reports that Hamels, Halladay, Lee, Kyle Kendrick, and John Lannan are all slated to pitch in order starting Saturday, with Halladay squaring off against Justin Verlander on Sunday.
