Robbie Ray's mom has proof her son has always been on the D-backs

Pitcher Robbie Ray got the call of his life last season when the Tigers were in need of a starting pitcher because Anibal Sanchez had to be placed on the disabled list. Ray went 1-4 in nine appearances for the Tigers, including six starts. 

Though his ERA left a lot to be desired (it was 8.16), Ray impressed the scouts in the Diamondbacks organization. So -- when the D-backs were gearing up to trade shortstop Didi Gregorius to the Yankees -- they made their move to acquire Ray from the Tigers, the third team involved in the deal.

The D-backs thought they were getting a great pitcher in the deal, but they didn't know they were getting a team lifer. On Sunday, Ray's mom tweeted out a primo photo of her son from way back in Little League ... when he was also a D-backs pitcher.

And then it was so.
