This isn’t as easy a question as it may seem. You can say we’re taking out the cost of losing that pitcher as a starter, which is obviously huge for Burnes, GRod, Bradish, Kremer and Means. Fine. However, only one pitcher, I believe, has actually closed games, and that is Wells. Some starters do not do well in the pen. They do not adjust to the routine as well, or they break down with the work load when they “air it out.”
If we assume they can make the adjustment, then Burnes. Not just on pure stuff, but his knowledge, experience and physicality are huge factors. Of course, Burnes would likely reject that move, as he should, just before his FA shot.
I voted Wells before I fully understood the question, because he has done it and his days as a starter are likely done here in Baltimore, unless there is a slew of injuries.
McDermott was not a choice, but he might actually be the guy for the job.
