My Initial take:
Looks like Elias is going with someone who can move quickly through the minors and be able to get and produce at the major league level quickly. While scouting takes on Cowser are a bit all over the place, he's a three year producer even though his conference is not very strong. He appears to be a high OBP guy with some pop and speed and even if Mullins is still center, he would like real good in Camden Yards spacious left field.
He appears to b a lower risk guy thoug
Off topic thought, after DL Hall, I can't picture any of our other pitchers from AA and up (still rookie eligible) that deserve to be in the top 10. Bauman, Kremer, Kevin Smith, Bradish, etc. group seem to be future middle relievers and old prospects (if 25 is consider old). However, I do hope for a John Means resurgence for one of them.
Well, its not very hard to take him from a starter and put him back in the pen.
However, they may not want to jerk him back and forth because of his injury history. Its a totally different way of preparing your arm and throwing when you go in short stints vs being a starter.
