"We almost got him in there," Gonzalez said. "He ran around, he felt better, but then the energy level started deteriorating a little bit."
Gonzalez said McCann was available to pinch-hit Sunday. Gonzalez is hopeful McCann can at least play most of Monday's game against the Cardinals, a move that is more viable because the Braves have three catchers on the roster.
"I said to Mac, 'If you come in tomorrow and feel good, let's give it a shot,'" Gonzalez said. "'If you catch five or six innings, that's three at-bats that we get out of you.' We're going to leave that open for tomorrow."
Backup catcher David Ross remains sidelined by a right groin strain he sustained Friday, though he said he felt better Sunday. Ross is available in an emergency situation and hopes to be back at full strength by Wednesday.Until McCann or Ross is fully healthy, J.C. Boscan, who was recalled from Triple-A Gwinnett on Saturday, will remain in the starting lineup. He went 1-for-4 on Saturday.
