When, in that situation, did you get your best reliever up and Warming?
If you waited until it was high leverage to do so, it's too late. So you had to have had your best reliever warming to start the 6th. And you'll need to do the same for each of the next 2 innings too, at which point he's unusable tomorrow.
I won't speak for Brock but what I'd do is use score as proxy for leverage. Tie game being the highest, +1 next, -1, next, and so on.
With a "lineup" for each score. Pressly and Rogers are #1 and 2 respectively in a tie or +1 score. Double barreled warm up with whoever matches up to batter handedness entering first. This is assuming the opponent is a conventional L-R-L-R lineup and not heavily platooned against the starter. In that event keep the opposite handed guy on the bench obviously.
In a +/- 3 run game, ie. low leverage, the lineup would be virtually flip flopped. With Belisle or Tonkin first out of the gate.
Basically, pitch to the score.
