Saltalamacchia was the designated hitter in the first game of his rehab assignment on Thursday, but was behind the plate in Friday's game. In 20 games for the D-backs this season, Saltalamacchia is batting .213 with a homer and four RBIs.
Hale said the plan remained for Saltalamacchia to return to the Major League roster and join fellow catchers Welington Castillo and Rule 5 Draft pick Oscar Hernandez.
"He'll be ready to come off when it's his day," Hale said.
The D-backs have another catcher who could soon be added into the mix as well in veteran Gerald Laird. The 35-year-old played in just one game this season before having back surgery on April 20.
Laird caught his first bullpen session on Friday and Hale said the veteran could be ready to go on a rehab assignment after the team's next road trip.
"He's doing great," Hale said. "Another catcher."
