"We still get confused for each other now and then," said Petersen, a non-roster invitee. "We're having fun with it. I think we're getting to the point where people can tell us apart, but just this morning someone was like, 'Hey, Matt!'"
"I'm not going to mention any names," Petersen said.
They usually play along.
"We did a little jersey switch during practice the other day," said Long, who was acquired in an offseason trade with the Dodgers. "I think most people are starting to recognize us, though. Earlier in camp, they would have had no idea."
Both are competing for a roster spot with the Brewers, but could also end up at Triple-A Colorado Springs. Even with 0-for-1s against the A's on Sunday, Long is hitting .385 in the Cactus League, and Peterson is hitting .313.
• Some hitters say it takes only one positive at-bat to feel locked in during Spring Training. Brewers catcher Jonathan Lucroy is not one of those hitters.
"I'm not locked in at all," Lucroy said after hitting a home run off A's ace Sonny Gray on Sunday. "It's going to take a whole lot more for me to get locked in. I'm not that good."
• Oh, to be a fly on the wall; Brewers catchers went to dinner as a group recently and invited legendary broadcaster Bob Uecker along. Uecker was a former big league catcher, of course, who brags often about leading the National League with 27 passed balls in 1967.
• The team returned non-roster catcher Perker Berberet, first baseman Hunter Morris, righty Tyler Cravy and lefty Brent Leach to Minor League camp on Sunday and have more moves pending. The other transactions should be announced before the Brewers return to action Tuesday against the Padres.
"We're starting to make moves," manager Ron Roenicke said, "and to get guys back to the Minor Leagues so they can continue to get ready for their seasons."
• The Brewers unveiled some new wall art at Maryvale Baseball Park on Sunday. They framed jerseys of their two new Minor League affiliates: Triple-A Colorado Springs and Double-A Biloxi.
