The Arizona Diamondbacks call up Jordan Lawlar, DFA Garrett Hampson and José Castillo, signaling a youth shift in NL West push.

D-backs manager Torey Lovullo told reporters that the current plan is to use Lawlar at several positions. He might not play every day, which makes the promotion somewhat curious, but the belief is that it's time for him to be in the major leagues.

Jordan Lawlar is off to a hot start in Triple-A Reno, prompting the call-up despite the Diamondbacks' depth at middle infield and third base.
