"Slight, slight, slight," said Padres manager Bud Black.
Because relievers don't need as many innings or appearances to get ready for the regular season, the Padres are taking the cautious route with Street.
"We're just being cautious and overly protective," Black said. "There's no schedule when he's going to pitch in a game. But he'll be fine. He wants to pitch."
When asked about the injury Tuesday morning, Street didn't seem too concerned.
"It's typical Spring Training tightness," Street said, before going off for treatment in the training room. "I'll be fine. I'll be in there soon."
The Padres won't have any trouble filling innings, as the team has yet to make a cut in camp and there are still 30 pitchers in big league camp, with no scheduled "B" games set aside to get pitchers extra work.
