Top prospect Bradley in running for final bullpen spot

Righty has been starter, but may be used in long relief; Lopez reassigned to Minors camp

Top prospect Bradley in running for final bullpen spot

SCOTTSDALE, Ariz. -- The D-backs' Opening Day pitching staff became a lot clearer Monday afternoon.

First, manager Chip Hale announced his rotation along with a handful of roster moves, and then, after the 4-2 loss to the Dodgers, Hale announced the team had reassigned Cuban free-agent pitcher Yoan Lopez to Minor League camp.

Hale also confirmed that there was just one spot left up for grabs on the staff, with Addison Reed, Brad Ziegler, Oliver Perez, Evan Marshall, Randall Delgado and Daniel Hudson having made the team.

Enrique Burgos, Andrew Chafin and Vidal Nuno are obvious remaining candidates for that last bullpen spot, and even though he's primarily a starter, lefty Robbie Ray was also assumed to be in the mix before Hale confirmed it.

But the most surprising development was that former No. 1 Draft pick Archie Bradley -- rated the club's No. 1 prospect by MLB.com -- was in the running. Bradley, who has had a good camp, has been a starter throughout his Minor League career and it was thought that he would either make the big league team as a starter or go to the Minors and start.

"They're candidates," Hale said of Bradley and Ray. "We talked about it before -- we like a guy that can throw multiple innings in that spot. They're both guys that can do that. The way the game was played for a long time, guys developed in that spot as [relievers]. You're able to watch their innings a little better and teach them at the big league level. They're going to get plenty of innings. If the situation arises where our starters are going seven or eight innings every night and that spot is not being used, then they will probably have to go back, if it's one of those guys."
