Chicago Cubs starter Matt Garza isn't worried about missing any time in the regular season, saying he was ahead of schedule on his lat injury that sidelined him after Sunday's outing.

"Right now, if I stay on my pace, stay patient and just let it heal, I'll be fine," Garza said. "I'll be ready."

Garza will rest a week or so before beginning throwing again. He said he's not thinking about a possible Opening Day assignment, but just wants to be ready for the season.

The rest could be good for Garza, who came out very strong in his first live batting practice session, when he felt something on his left side and had to shut it down 20 pitches into a scheduled 40-pitch session.

"Obviously that's a sign," he said. "Maybe I came out too strong, too fast."

Garza said Cubs physician Stephen Adams told him to "relax and enjoy it a little bit, because this is probably the last time you'll be off."
