MIAMI -- Sunday's starter is up in the air with the scheduled bullpen session for Taijuan Walker (blister) pushed back another day. That counts him out as Arizona's starter when it closes a four-game series with Miami at Marlins Park.
"It's not quite 100 percent, but it's getting better," Walker said prior to Friday's game. "It's a no-go for Sunday. We just want to be smart with it. It's still pretty early in the season, and we want to make sure it's 100-percent healthy so we don't have any setbacks."
Manager Torey Lovullo said he has a couple of options that the organization is still weighing before making a decision on a Sunday starter.
