A source tells Tim Williams of Pirates Prospects that Elias Diaz will join the Pirates as a September call up to be the third catcher.
Diaz signed with the Pirates out of Venezuela back in 2008. Since joining the organization, he’s been an above average catcher defensively, and has really made strides with the bat the last couple of years. In 93 games played this season with AAA Indianapolis, Diaz is hitting .271 with a .711 OPS while throwing out baserunners at a 30% clip. He is the Pirates 14th best prospect according to MLB.com.
