• Jake Arrieta, slowed this spring because of tightness in his right shoulder, is taking part in the Cubs' pitcher drills but has yet to throw off the mound. Arrieta has been able to play catch and is making progress, manager Rick Renteria said Sunday.
• Renteria, who had hip replacement surgery in October, walked around the Cubs' complex for nearly 45 minutes beginning at 5 a.m. MT on Sunday as part of his exercise. "The catchers are working early," Renteria said. "I'm not asking them to be out and do anything I wouldn't do. [My early work] kind of re-enforces that."
• Albert Almora and Josh Vitters reported to Cubs camp on Sunday, joining Bryant and Brett Jackson. The first full-squad workout is Wednesday.
"I've been pretty impressed with the fact that the numbers are kind of high," Renteria said of the early birds. "It shows me a lot of interest. First of all, I'm sure they want to see the new facility. ... No one is making them be here, they've chosen to be here. It's nice to have them preparing for what will hopefully be a very good season."
