"Since I've been here, I feel like every day I've been getting better," said Paulino, who acknowledged that the toughest part of being a late arrival is getting to know all of the pitchers in a new organization.
"Every day I am catching a different guy," he said. "But at the same time, it's helping me get the chance to know each of the guys."
Paulino is competing for the role of backup to Matt Wieters, a job that is still largely up for grabs given Taylor Teagarden's back injury and Paulino's late start.
"We've got some options to pick from, and we will continue to look at them behind Matt until we have all the information that the time will allow us to gather, whether it be health or an evaluation," manager Buck Showalter said. "We still have some things up in the air behind Matt, so we will take the time to answer those questions."
Dan Duquette, executive vice president of baseball operations, acknowledged earlier this week that the organization is very unlikely to add a catching option at this point, and Showalter echoed that on Saturday.
"One of the hardest things to find, always, is [a backup catcher]," he said. "We are happy with our options here, and we will see which way we go."
