Arencibia has been catching regularly in Minor League games as the Orioles wanted him to get into the swing of things.
He had a slow start defensively in the Grapefruit League and Showalter thinks he was trying too hard to impress his new organization.
"I sat down with him three or four days ago, I said, 'is there something we can do different?' Because I know he's so much better than he's shown," Showalter said. "And he has. Yesterday I was reading the [Minor League] reports about him coming over here. Pretty effervescent yesterday."
"He's going to be a guy if he ends up in Triple-A, if he does, you are going to like him around the players. It's not like he's 40 years old. This guy likes to play. For a guy that's played four or five years in the big leagues, nothing is beneath him.
"He and [Ryan] Lavarnway both are very intrigued with what they heard about John Russell and the catching program. First thing they did when they walked in was, can we try that? Some of the footwork that [Caleb Joseph] and the other guys are doing. He [was] very receptive from Day 1."
