I would have to lean towards both inexperienced starters at pitcher and catcher staying in their comfort zones.
You've got Moore or Johnson behind the plate, they stick their glove on the black and Fister hits them right in the pocket with the ball ... then next pitch is on the hands and right in the pocket again ... very easy to play tic-tac-toe all night...
While I preach (to distraction) a philosophy based on beating guys with what they know is coming, I can't justify losing with what amounts to sub-standard stuff.
Certainly would agree that with a Shawn Kelley, Mark Lowe, whoever ... the hitter looks fastball, gets fastball and fouls it back ... now he is done whether the next one crosses him up or not...
Have nothing against running Larry Csonka on every 1st-and-10, if you've got Csonka to hand the ball to :- )
