CHICAGO - The Chicago Cubs placed three players on the injured list, including starter Jake Arrieta, infielder Nico Hoerner and reliever Dan Winkler, the team announced on Tuesday morning.
Arrieta has been plagued by a cut on his right thumb which impacted his last start while Hoerner injured his left forearm colliding with centerfielder Ian Happ as the two converged on a ball in Sunday's game against the Cincinnati Reds. Winkler has right triceps tendinitis.
"We're optimistic about everyone, to be honest with you," Cubs manager David Ross said.
