HTBT...If the ball was in front of the plate....Fair Ball...Partner needs to keep thy mouth shut unless asked.
2 Weeks ago, the Mrs. is on the plate, I'm at first, NCAA D1 Game....Same thing. Bunt, close to being Fair/Foul, from 1st it looked fair, she called foul, I thought "Okay...Maybe I missed something". 1st base coach asks...."Did you call that?" "Nope" "It looked fair..." "
called it foul coach.".
Now what I am leaving out is this....I know her reactions, no matter how subtle so well, I KNEW she kicked it....After the game....Mrs. "Remember that bunt foul in the 2nd inning?" "Yep....You kicked it didn't you?" Stunned Look on her face...I said "That's Okay...the first round is on you now." Our third, who is a pretty good friend of ours just looked on in awe.... 
The coolest thing, except for Mrs. and myself no one else had a clue.....
