"As a whole the bullpen went through some trials early on," Rosenthal said. "It's good to see now that everybody's kind of coming together and figuring some stuff out. That's what this game is about: Going through things and having to make adjustments."
Rosenthal, a starter in the Minor Leagues, was inserted into the eighth-inning setup role when Jason Motte's absence shuffled the bullpen responsibilities.
"It's definitely an adjustment," he said. "Every day you learn something new. Just being in the bullpen in general is something I'm not used to.
"It's just fun to be out there and compete, and be in different situations and see what I can do."
