Graveman (elbow) is scheduled to start Tuesday's Cactus League game against the Brewers, Ryan Divish of The Seattle Times reports.
Graveman signed a one-year, $1.5 million deal with the Mariners in November after missing all of last season due to Tommy John surgery in July 2018, and he's set to debut for the team in its third spring game. The 29-year-old made a good early impression in camp and should be in the mix for a spot in Seattle's starting rotation with a decent showing in spring training.
