They won't, and shouldn't, make a move soon. However, once you start rolling into May/Mid-May if someone is still bombing it often you just can't afford that . I mean by mid May they will have plenty of starts under their belt. I would replace someone at the start of May if they are really just getting murdered out there. You can't be sitting there going three innings and giving up 4/6 runs. You are destroying the bullpen, giving up a ton of runs, and then the bullpen will give even more runs. You are single-handedly losing the game...essentially giving the team no chance to win. Barring one heck of an offensive performance and amazing bullpen work. I am not saying we need Keuchel or need to replace these guys, merely saying if things don't get WAY better from the trio of young guys they can't afford to give them 150+ innings on this team. We will sink our year letting guys throw 150+ innings of 5 ERA or worse ball.
