Yep, it's a decent use of the resources he has. It makes me wonder, aside from Marquis and Z, what pitchers do we have with decent speed? The next one would be Marmol. After that, it's a tough question. Dempster maybe? or Wood? They're all pretty terrible at that point, although there's probably one random reliever that's a much better baserunner than we realize. dempster is really slow. Pitchers are bizarrely slow in general. Hill and Lilly are both not much faster than Ward, which is sort of pathetic. You're almost never going to use a RP as a PR, so it's effectively limited to SP, I suppose Clement always ran like he weighed 400 lbs, making him my favorite pitcher/runner
