When Tommy Henry got called up a little over 10 days ago to take the place of Madison Bumgarner in the D-backs rotation, general manager Mike Hazen was asked why it wasn’t right-hander Brandon Pfaadt.

It was, in part, Hazen said, because of the way Pfaadt’s rotation turn lined up, but he also made it clear that Pfaadt’s time was coming.

“Brandon is going to pitch up here, and he's going to be a very good player for us,” Hazen said. “And it's going to come. But it's not going to come right this second.”

Instead, it will come Wednesday against the Rangers in Arlington. Pfaadt will take the place of Drey Jameson.

Jameson, who made the Opening Day roster as a reliever after losing out to Ryne Nelson for the final rotation spot, was shifted to the rotation after an injury to Zach Davies. Jameson was demoted to Triple-A Reno after lasting just one inning against the Padres.

Pfaadt, the team's No. 3 prospect, was speculated about as the one to take Jameson’s place, but with a host of off-days this past week, the D-backs were able to keep some of their veteran pitchers on regular rest before having to add a fifth starter. Tuesday, the news became official.

“We’re all really excited about that for him and this opportunity,” D-backs manager Torey Lovullo said. “He’s worked hard to make it happen ... that’s come from a lot of great instruction and player development, and it’s come from the trust and the ability to go out there and execute.”
