Montgomery will compete for a rotation spot in spring training, Ryan Divish of the Seattle Times reports.
EDGE Analysis
General manager Jerry Dipoto did add that Montgomery could be moved to the bullpen, and considering his emphasis on acquiring starting pitching so far this offseason, that's the likely plan barring injury. The Mariners traded for Nate Karns a few weeks ago and brought in Wade Miley from the Red Sox on Monday. Montgomery put himself on the map last season by posting a 1.62 ERA in his first six starts, but faltered down the stretch, allowing 21 runs in his final 19.2 innings.
