3/5 Arrieta update
Jake Arrieta, slowed this spring because of tightness in his right shoulder, threw 10 pitches off the mound on Tuesday, the first time he’s thrown off a mound.
“It felt awesome,” Arrieta said.
The right-hander is hoping to catch up to the other Cubs starters and be ready by Opening Day.
“My endurance is ahead of schedule,” Arrieta said.
