When the Cubs broke camp at the end of March, Trevor Cahill and Adam Warren were stretched out enough for a spot start or long relief duty if necessary. Joe Maddon said last month that Cahill was actually the team’s sixth starter if the Cubs needed help in the rotation beyond Jake Arrieta, Jon Lester, John Lackey, Jason Hammel and Kyle Hendricks.
According to multiple reports after Tuesday’s game, Adam Warren has moved up the depth chart and is actually the team’s sixth starter.
