The Braves' closer has had a strong start to the season with 5 saves, ranking 8th among relievers. His shoulder injury has placed him on the 15-Day IL.

Matthew Boyd

The Cubs' ace is due back to start on Wednesday night against the Phillies. Boyd is at no risk post-bicep injury.

Lodolo has been out on the 15-Day IL. He expects to return to the Reds rotation on Friday, April 24, and shall be fantasy viable.

Justin Verlander

AJ Hinch told reporters last week that Verlander is progressing more slowly than hoped for. This is no surprise given his age. Verlander's return is not yet set in stone, but is expected within the next 1-2 weeks. He may want to be sat in the fantasy baseball in the short term.
