I guess I'm the only one but I'd take the righty, #2, last. He's better against righties, but his splits are still a fair amount lower cumulatively than the other pitchers. He's the farthest away from his projections, along with #3. And though there are more righties, I'm not sure it makes that much of a difference. Any ies will hit him hard as that split won't likely get over 55.
I'd go with #1. Low groundball matters some depending on the park, but I've also seen guys with lower velocity have some struggles. Will have both splits over 60, projected not to have any weak pitches and 2 good ones. 20 scouting is as accurate as you can get but I'd still factor in how advanced they are. Its rare for guys drafted out of high school with a split of 40 to get it up over 60, so I see #2's y split being a problem. I have good coaches, and have never looked at patience or makeup. I haven't seen to have had a problem with guys developing despite this.
