Chatwood, 26, and Lyles, 25, could be keys in Colorado's plan for improving its starting pitching. The Rockies sent catcher Chris Iannetta to the Angels for Chatwood, a second-round pick in the 2008 Draft. Lyles was an Astros first-round pick, also in '08, who came with outfielder Brandon Barnes in a trade for center fielder Dexter Fowler. Such deals, as well as pickups of Chris Rusin, David Hale and Jeff Hoffman -- who was acquired in the Troy Tulowitzki deal at the '15 Trade Deadline -- deepen the Rockies' cadre of high-quality arms and give the team a margin of error with its own early picks.
