While Welington Castillo was an offensive force for the D-backs last year, he did not rank highly when it came to pitch framing.
The desire to improve in that area was one of the leading motivators in signing free agents Jeff Mathis and Chris Iannetta to go along with Chris Herrmann.
"That was Spring Training," Hammock said of the success. "But it was encouraging. We'll monitor it as the season goes on and see how it ends up."
Ready to go:Shelby Miller will make his first start of the year Friday against the Indians, the final Arizona starter to take the mound, and for him, it can't get here quick enough.
"I can see the excitement in his eyes," D-backs manager Torey Lovullo said. "I know that he has a lot to prove."
Miller struggled last season, compiling a 6.15 ERA and spending time at one point in the Minor Leagues. He finished the year with two strong starts and followed that up with a good spring.
"I wouldn't say I'm nervous," Miller said of his pending first outing. "I'm just more anxious than anything. Definitely ready to go, feeling great."
No change in roles: Despite a good Spring Training and a dominating 3 1/3 innings of relief against the Giants on Tuesday night, Lovullo does not plan on using right-hander Archie Bradley in more high-leverage situations right now.
