 Just a run on three hits over six innings. Walk two struck out nine. Lifetime against Arizona. Sales a perfect 2-0 with a .253 ERA in two career starts. Diamondbacks have not officially announced a starter as of yet. We do believe it could be Gilbert Diaz making his major league debut. The 23-year-old right-hander has spent four seasons in the minors with the Diamondbacks. And again, he has a locker in Arizona's clubhouse. They have not officially announced anything, but it looks like it could be Diaz making his big league debut coming up tomorrow night.
