PHOENIX -- The D-backs put an emphasis on pitch framing this spring, and catching instructor Robby Hammock was pleased with the results.
"The numbers looked pretty good during Spring Training," Hammock said, referring to internal numbers the club looked at.
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.
