Ohlman appeared in two games, going 2-for-3 with a pair of RBIs while Ward went 1-for-2 in three games. Berry allowed a run on two hits over three spring innings (two appearances).
Manager Buck Showalter was particularly impressed by Berry, who was protected on the 40-man roster this winter, and will be part of the Baysox rotation.
"Very intriguing what the future may hold for him," Showalter said. "I think it's going to be a big year for Berry. I think he's got a chance to really pop."
