Who knows where the evolution of the pen is heading?
If anyone might try something out of the box, it might be Bloom & Cora.
However, I seriously doubt anyone is even talking about what I suggested might be a way to get the most out of Houck and Whitlock. The reason I'm thinking like this is that they both seem to excel in long relief. We know they do. We also know Houck seems to have issues going past 2 times through a line-up.
Both would probably make great 1 inning guys (45-55 appearances).
Both might make great starters, even if they don't get past 4 or 5 innings. These days, that's not a fault.
We have seen some tinkering with established roles over the last decade. Andrew Miller was one. I think he had over 70 appearances 2 or 3 times in his career and was used for more than 1 inning quite a few times.
Chad Green had 67 appearances and 84 IP, this year.
Nabil Crismatt had 81 IP in 45 games, which is very close to 2 IP every 3 games.
Whitlock pitched in almost a third of our games, this year (46) and went 73.1 IP.
He had a stretch in April, where he did this:
3.1 IP
2.0 - 4 days later
1.0 - 6 days later
2.2 - 4 days
2.1 - 4 days
2.0 - 5 days
That's not really the same as what I am suggesting as a possible plan, but it's not far off, either.
