According to Bob Przybylo, Robinson Tejeda will in fact be designated for assignment to clear room for Dustin Nippert to make the opening day roster. Two comments from Daniels:
"He's going to take that last bullpen spot," Daniels said. "He's a big, durable guy who we feel can do many different things for us."
"Dustin's been a starter in the past, but he's also been an effective late-inning reliever," Daniels said.
