I know very well both started much of the season. Maybe it wasn't the best example as both were signed with an apparent understanding they'd start.
I'm not sure Wacha was promised anything about starting other than he will start as the front runner for the 5 slot. I would think Hill would have a better understanding he'll be starting, but the quote I provided by Cora sounds like he's is viewed as a flex pitcher. I'm not sure what, if any, promises were made, but Nick sure sounded like he thought it would be a "LIE" if they put either in the pen after adding another SP'er. Then, he yelled, "How the f*** do I know what was promised?"
All i know is, teams often add starters to the mix and more than 5 think they should or will start, but one or more do not, at the start of the year.
This all came about as a result of me just suggesting 3 ways we could add a starter and make it work. I never said we would or should choose one of the suggestions that said we might move Hill or Wacha to the pen. Hell, many here have been saying Houck and or Whitlock should start, which would mean someone goes to the pen, barring injury.
I seriously doubt Wacha will be all that upset, if someone else beats him out of the 5 slot. He pitched 6 games from the pen, last year, including one near the end of the year. He had an ERA of 5.00, too, so why should he feel like he's earned anything?
Hill is another story. He's been an exclusive starter for so long, and being so injury prone, I'm not sure I'd mess with him. I'd only put him in the pen, if he's sucking or worse than Wacha or Pivetta as the season progresses.
