Wieland was traded to the Braves on Wednesday, ESPN's Jerry Crasnick reports.
The return package for the Mariners has not been announced, but it could simply be in exchange for cash or a player to be named later. Wieland is now on his fifth organization, despite being just 26 years old and having only 52.2 MLB innings under his belt. The Braves are extremely thin in the rotation due to injuries, so it's possible Wieland could receive a start or two down the stretch, perhaps as soon as Saturday against the Nationals.
