The strategy is sound, Knebel has started plenty of bullpen games and Urias has
Done well coming out of the bullpen. If the Giants adjust their lineup, it works because it gets the Giants to adjust their lineup. If they don’t adjust, Knebel takes on RH Batting at the beginning of game and Urias comes in facing later hitters.
It could easily blow up, but not sure that makes it a bad strategy.
